The term acute kidney injury (AKI) has replaced the historical term acute renal failure for renal damage occurring over a short period of time (hours to days) because it is thought to better describe the pathophysiologic changes and duration of the different phases of injury. There are many potential causes of AKI in dogs and cats, and the prognosis has been shown to vary with the cause as well as with therapy. This article reviews current concepts of the pathophysiology, causes, clinical presentation, approach to diagnosis, and medical management of AKI in dogs and cats.

This study was conducted for the purpose of long-term monitoring of changes in the sociability of group-housed cats towards a familiar caregiver in a private no-kill shelter. The sociability of the monitored cat population was assessed at two-week intervals during one calendar year. A total of 158 animals were rated on a 5-point scale, the individual levels of which represented the level of sociability (1-very friendly cat to 5-very unfriendly cat). The evaluation was performed by visual observation of the cats' response to human approach and contact by one observer. At the first assessment, more than three quarters of the cats (81%) showed very friendly (score of 1) or friendly behavior (score of 2). Of the 88 cats that were evaluated at least twice and at the same time their stay in the shelter terminated during the monitoring period, 56 cats (63.6%) did not change their score (worsen or improve) during their stay in the shelter. Among the cats with an observed change, there was a permanently improved score in a significantly higher number of cats (P 0.05). The sociability level at the first assessment was found to be a predictor of the sociability level at the last assessment (P

Introduction /Objectives: The objectives were to conduct a survey of cardiologists on their recent experiences with cats that have dilated cardiomyopathy (DCM), and to retrospectively review individual cases of feline DCM. Animals, Materials and Methods Part One: A survey was distributed to cardiologists with questions regarding caseload and clinical management of cats with DCM diagnosed over the past two years. Part Two: Cardiologists completing the survey were invited to submit data from cats recently diagnosed with DCM. Data on signalment, clinical signs, diet, echocardiographic measurements, and outcome were recorded. Results Part One: From 52 completed surveys, many cardiologists responded that measuring and supplementing taurine and recommending a diet change in cats with DCM are common practices. Few (15%) cardiologists reported an increase in number of feline DCM cases over the past two years, although some had cases that improved even if taurine deficiency was not present. Part Two: Twenty of 37 (54%) cats ate low pea/lentil (low PL) diets and 14/37 (38%) ate high pea/lentil (high PL) diets at the time of diagnosis; three had incomplete diet information. Two of 13 cats (15%) in which taurine was measured had levels below the reference range. After adjusting for other variables, cats eating high PL diets that changed diets post-diagnosis had a significantly longer survival time compared to cats eating high PL diets that did not change diets post-diagnosis (P=0.025). Conclusions Additional research is warranted to determine whether there could be a possible association between diet and DCM in cats.

An understanding of feline behavior is required to successfully handle cats in the hospital environment and avoid triggering escalation to fear-aggression due to heightened anxiety. Some veterinary students appear to misinterpret feline behavioral cues, resulting in frustration and poor success when performing basic handling. This article investigates the following in regard to veterinary students and feline handling: (a) attitudes toward working with feline patients in the hospital environment; (b) experience of working with feline patients; (c) satisfaction in acquisition of feline handling and examination skills; and, (d) confidence in feline handling skills; and to explore influencing factors. An electronic questionnaire was circulated to fourth and final year veterinary students (May 2012) and final year students (June 2013) for anonymous voluntary completion. One hundred and seventy-three of 293 students completed the questionnaire. Of final year respondents, 87/115 (75.7%) indicated that they enjoy interacting with cats in veterinary hospitals; 95/115 (82.6%) indicated that they were satisfied with their cat handling skills; 105/115 (91.3%) felt confident handling quiet and wriggly cats; significantly fewer 63/115 (54.8%) felt confident handling unpredictable cats ( p < .05). Factors significantly affecting confidence in handling unpredictable cats included: frequency of examination practice during extra-mural studies ( p < .05), enjoyment of interacting with cats in veterinary hospitals ( p < .05), self-perceived understanding of feline behavior ( p < .05), self-perceived ability to interpret cats’ behavioral expressions ( p < .05), satisfaction with cat handling skills ( p < .05), and perception of feline versus canine handling ability ( p < .05).

OBJECTIVE To determine the number and species of animals cared for by the PetSafe program at the Purdue University College of Veterinary Medicine (a community service offered to meet the short-term housing needs of pets, especially pets owned by victims of intimate partner violence) from 2004 through 2019 and collect information on duration of stay, outcome, health problems, and expenses. ANIMALS 229 animals cared for by the PetSafe program. PROCEDURES Medical records were reviewed for information on species, breed, age, duration of stay, outcome of stay, client referral source, whether the animal had been cared for previously, health problems, medical interventions, and expenses incurred. RESULTS There were 124 dogs, 95 cats, 6 ferrets, and 4 sugar gliders; 187 of the animals were returned to their owners, 37 were rehomed, and 5 were euthanized because of medical conditions. The most common health problems were dental disease and dermatological complaints (eg, flea infestation and resulting fleabite dermatitis). None of the animals had physical evidence of abuse. Mean duration of stay was 22 days (range, 1 to 93 days), and mean ± SD cost per animal was $368 ± $341. CLINICAL RELEVANCE Over the 16-year period of the study, the number and species of animals cared for by the PetSafe program at Purdue and the health problems encountered in those animals were relatively stable, and the program was able to meet the relatively predictable financial costs incurred through existing sources of funding.

A 1-year-old domestic shorthair cat was evaluated for a chronic history of back pain, dysuria, and paraplegia. Radiographic and computed tomographic examinations showed circumferential widening of the vertebral canal at T13 and T14. A spinal epidural abscess (SEA) compressing the spinal cord from the level of T11 to L1 was suspected following intravenous contrast administration, and was confirmed by surgical exploration and histopathological analysis. The cat recovered its motor and bladder functions following surgical decompression and antibiotic therapy. SEA is a neurological emergency requiring prompt treatment. However, the present case had a prolonged disease course and pressure atrophy of the vertebrae was strongly suspected. To our knowledge, this imaging finding has not been reported in dogs or cats with SEA.

OBJECTIVE To determine whether intrarenal injection of sodium pentobarbital is a viable method for euthanasia in anesthetized client-owned cats and assess potential factors associated with time to cardiopulmonary arrest (TCPA) for such treated cats. ANIMALS 131 client-owned cats. PROCEDURES In this retrospective study, client-owned cats presented for euthanasia between March 1, 2009, and January 15, 2010, were evaluated by veterinarians to determine suitability of intrarenal injection versus other methods of euthanasia. Cats included were anesthetized and then received 6 mL of sodium pentobarbital (390 mg/mL) by intrarenal injection. Results for TCPA were compared for cats grouped on the basis of variables of interest. RESULTS 131 cats were included, of which 74 (79%) had a TCPA < 1 minute and 28 (21%) had a TCPA between 1.5 and 8 minutes after intrarenal injection. Most (124/131 [95%]) cats had no observable reaction to the intrarenal injection other than cardiopulmonary arrest. Median TCPA was longer for cats without (1 min; 25/131 [19%]) versus with (0 min; 106/131 [81%]) palpable kidney swelling upon injection. CLINICAL RELEVANCE The effects of intrarenal injection of sodium pentobarbital in cats of the present study were similar to those typically observed with IV administration of euthanasia solution. When this intrarenal injection method is used, cardiopulmonary arrest with few agonal reactions can be expected to occur quickly in most patients. The intrarenal injection method is suited for euthanasia of anesthetized cats with easily located kidneys when IV access may be difficult.

BACKGROUND: Radioiodine (131 I) is the treatment of choice for cats with hyperthyroidism. After 131 I, however, euthyroidism is not always achieved, with 5% to 10% of cats remaining persistently hyperthyroid and 20% to 50% developing iatrogenic hypothyroidism. OBJECTIVES: To identify pretreatment factors that may help predict persistent hyperthyroidism and iatrogenic hypothyroidism after treatment of cats using a novel 131 I dosing algorithm. ANIMALS: One thousand and four hundred hyperthyroid cats treated with 131 I. METHODS: Prospective, before-and-after study. Pretreatment predictors (clinical, laboratory, scintigraphic, 131 I dose, 131 I uptake measurements) of treatment failure or iatrogenic hypothyroidism were identified by multivariable logistic regression analysis. RESULTS: Cats that developed iatrogenic hypothyroidism were more likely to be older (odds ratio [OR] = 1.10; 95% confidence interval [CI], 1.04-1.17; P = .001), female (OR = 2.04; 95% CI, 1.54-2.70; P < .001), have detectable serum thyroid-stimulating hormone (TSH) concentrations (OR = 4.19; 95% CI, 2.0-8.81; P < .001), have bilateral thyroid nodules (OR = 1.57; 95% CI, 1.19-2.08; P < .001), have homogeneous, bilateral distribution of 99m Tc-pertechnetate uptake (OR = 2.93; 95% CI, 2.05-4.19; P < .001), have milder severity score (OR = 0.62; 95% CI, 0.49-0.79; P < .001), and have higher 131 I uptake (OR = 2.40; 95% CI, 1.75-3.28; P < .001). In contrast, cats remaining persistently hyperthyroid were more likely to be younger (OR = 0.81; 95% CI, 0.72-0.92; P < .001), have higher severity score (OR = 1.87; 95% CI, 1.51-2.31; P < .001), and have lower 131 I uptake (OR = 3.50; 95% CI, 1.8-6.80; P < .001). CONCLUSIONS AND CLINICAL IMPORTANCE: Age, sex, serum TSH concentration, bilateral and homogeneous 99m Tc-pertechnetate uptake on scintigraphy, severity score, and percent 131 I uptake are all factors that might help predict outcome of 131 I treatment in hyperthyroid cats. Cats with persistent hyperthyroidism had many predictive factors that directly contrasted those of cats that developed 131 I-induced hypothyroidism.

OBJECTIVE To describe clinical outcomes in cats with insulin resistance and acromegaly treated with stereotactic radiosurgery (SRS). ANIMALS 14 client-owned cats. PROCEDURES Medical records of cats with insulin resistance and acromegaly treated with SRS (17 Gy) between August 2013 and November 2019 at a single institution were reviewed. Kaplan-Meier analysis was used to evaluate overall survival time. RESULTS Acute adverse effects of SRS included somnolence (n = 2) and alopecia (1). Delayed adverse effects of SRS included unspecified neurologic complications (n = 1; 481 days), seizures (1; 1,541 days), and hypothyroidism (1; 64 days). Exogenous insulin requirements decreased in 10 of the 14 cats, with a median time to lowest insulin dose of 399 days (range, 42 to 879 days). Complete diabetic remission was achieved in 3 cats. The median overall survival time was 741 days (95% CI, 353 to 1,129 days). Six cats were still alive at the end of the study period, with a median follow-up time of 725 days. In 7 of the 8 cats that had died, death was presumptively attributed to acromegaly owing to continued insulin resistance, organ failure, or altered neurologic status. CLINICAL RELEVANCE The SRS protocol was well tolerated and associated with survival times similar to those reported previously. Most cats had decreased exogenous insulin requirements after SRS. Latency to an endocrine response was highly variable, emphasizing the need for careful ongoing diabetic monitoring of acromegalic cats after pituitary gland irradiation.

Background Cytauxzoon felis is a life‐threatening protozoan disease of cats. Identification of schizont‐laden macrophages is a point‐of‐care diagnostic test for acute cytauxzoonosis. Hypothesis/Objectives The primary objective determined cytologic agreement between sample types to diagnose acute cytauxzoonosis. The secondary objective evaluated novices' ability to identify cytauxzoon organisms in blood films and tissue aspirates. Animals Thirty‐eight cats with suspected acute cytauxzoonosis and 5 controls examined postmortem. Methods Cases were prospectively submitted and collected. Blood film, lymph node, and splenic aspirates were blindly reviewed for sample quality, presence of schizont‐laden macrophages, and agreement between sample types. A subset of cases and controls were evaluated by 12 blinded novice observers to determine sensitivity and specificity for identifying organisms in various sample types. Results Acute cytauxzoonosis diagnosis was made on at least 1 sample type in 28/38 cats. Schizont‐laden macrophages were seen on 33% (10/30) of blood films, 56% (19/34) lymph node aspirates, 77% (26/34) splenic aspirates. Schizont‐laden macrophages were more likely seen on splenic than lymph node aspirates (McNemar's, P = .03) or blood film (McNemar's, P =

Background There is no standardized methodology to measure antibiotic drug use (AU) in small animal veterinary hospitals. Objectives To estimate AU prevalence in a small animal veterinary teaching hospital and characterize usage by indication and evidence of infection. To establish an AU measurement methodology for veterinary settings. Animals Electronic medical records of cats and dogs seen by primary care, urgent care, emergency and critical care, internal medicine, and surgery services during November 2018 to October 2019. Methods On 1 day each month, data (signalment, visit reason, diagnostics, and antibiotic details, including indication) were collected for all animals seen on study services. Results Of 168 inpatient dogs and 452 outpatient dogs, 98 (58.3%) and 107 (23.7%,) were receiving at least 1 antibiotic on the day of data collection, respectively. For cats 15/49 (30.6%) inpatients and 29/187 (15.5%) outpatients were receiving at least 1 antibiotic. Common drug classes prescribed for dogs were potentiated penicillins (28.7%), first‐generation cephalosporins (22.1%), and nitroimidazoles (14.7%), and for cats, common drug classes administered were potentiated penicillins (26.9%), fluoroquinolones (13.5%), and penicillins (11.5%). Common indications for antibiotics included skin, respiratory, gastrointestinal, perioperative, aural, and urinary conditions. Conclusions and Clinical Importance Serial point‐prevalence surveys (PPS) can estimate AU in a large specialty hospital setting and identify targets for antimicrobial stewardship. The methodology developed during this study can be adapted for use in private practice, including large animal practice. Mirroring methods used in human healthcare, the data collection tool can also be used to describe AU nationally through completion of national PPS.

The aim of this study was to determine if stimulation of sacral spinal nerve roots can induce defecation in cats. In anesthetized cats, bipolar hook electrodes were placed on the S1-S3 dorsal and/or ventral roots. Stimulus pulses (1-50 Hz, 0.2 ms) were applied to an individual S1-S3 root to induce proximal/distal colon contractions and defecation. Balloon catheters were inserted into the proximal and distal colon to measure contraction pressure. Glass marbles were inserted into the rectum to demonstrate defecation by videotaping the elimination of marbles. Stimulation of the S2 ventral root at 7 Hz induced significantly (p

Anthelmintic resistance (AR) has thus far only rarely been reported for intestinal helminths of dogs and cats, in contrast to parasites of livestock and horses. We highlight possible reasons for this striking and important discrepancy, including ecological, biological and genetic factors and/or intervention regimens of key intestinal helminths concerning both host groups. In view of the current knowledge related to the genetics, mechanisms and principles of AR development, we point at issues which in our view contribute to a comparatively lower risk of AR development in intestinal helminths of dogs and cats. Finally, we specify research needs and provide recommendations by which, based on the available information about AR in ruminant and equine helminths, the development of AR in dog and cat helminths may best be documented, prevented or at least postponed., Graphical abstract Image 1, Highlights • Identifying causes of differences in anthelmintic resistance between livestock and dogs & cats. • Discussion of roles of AR mechanisms, genetics and husbandry in delayed AR evolution in dogs & cats. • Research needs for improved tools to monitor AR development in dogs & cats.

The objective of this article is to compare the occurrence of hemorrhagic complications in student-performed feline ovarian pedicle ligations using the traditional suture pedicle double-ligation (PDL) to the suture-less auto-ligation (AL) techniques, and to describe the stepwise method of teaching the AL technique to students. A total of 287 cats underwent an ovariohysterectomy (OHE) performed by a fourth-year veterinary student trained by veterinary faculty to perform the AL technique beginning with a low-fidelity model and progressing to live patient surgeries. Students performed the AL and PDL techniques on 146 and 141 cats respectively. Hemorrhagic complications occurred in 4 of 146 cats (2.7%) in the AL group and 8 of 141 (5.7%) in the PDL group and were not found to be significantly different ( p = 0.2496). This article demonstrates that novice surgeons can safely perform the AL technique on feline ovarian pedicles without significantly increasing complications compared to the traditionally taught method when a stepwise training program is implemented. Additionally, this technique has been shown to be safe, effective, and more efficient when performed by experienced veterinary surgeons. 1 Veterinary institutions should consider including the AL technique in their core curricula as a standard method for feline ovarian pedicle ligation. Doing so will facilitate the development of more proficient entry-level practitioners who are better able to serve their patients, clients, employers, humane societies, and their communities by using a more efficient and safe feline ovariohysterectomy technique.

Renal cortical anisotropy backscattering artifact (CABA) is a focal hyperechoic region where the tubules are parallel to the incident ultrasound beam, reflecting most of the beams to the transducer. To investigate the association between chronic kidney disease (CKD) and the absence of renal CABA in cats. Ultrasonographic renal images of 40 cats with CKD (stage II-IV) and 36 clinically healthy cats were blindly evaluated by two observers to determine the visibility of renal CABA. Inter- and intraobserver agreements were evaluated using McNemar’s test. The association between the absence of renal CABA and CKD was assessed using Fisher’s exact test. Excellent intraobserver and substantial interobserver agreements were demonstrated. A significant association (P < .0001) between absent renal CABA and CKD stage was revealed in all cats. Cats with CKD had an increased risk of the absence of renal CABA (Odds ratio, 56.0; 95% CI, 13.8–227.0) compared with the clinically healthy cats. The absence of renal CABA revealed 87.5% sensitivity and 88.9% specificity to detect CKD in all cats, and 91.7% sensitivity and 83.3% specificity in aged cats. Our study demonstrated a correlation between feline CKD and the absence of renal CABA, providing a feasible and alternative method for feline CKD evaluation.

OBJECTIVE To investigate the effects of a single oral dose of gabapentin on fear-based aggressive behaviors (FABs) in cats during veterinary examinations. ANIMALS 55 healthy pet cats (26 with and 29 without a history of FAB during veterinary visits [FAB and untreated control groups, respectively]). PROCEDURES A standardized 9-step clinical examination protocol (with patient compliance scored from 0 to 9 according to the highest completed step) was tested on untreated control group cats. The protocol was then used in a double-blind, randomized, placebo-controlled, crossover-design trial in which FAB-group cats received owner-administered gabapentin (100 or 200 mg/cat) or placebo capsules 2 hours before the first of 2 veterinary visits and received the alternate treatment before the second visit ≥ 1 day later. Ease of administration (scored from 1 [very difficult] to 4 [very easy]) and adverse effects were recorded. Compliance scores were compared between treatments for the FAB group and between FAB and untreated control groups. Changes in scores between treatments for the FAB group were used to investigate associations between selected variables and the outcome of interest. RESULTS FAB group compliance scores after gabapentin administration (median, 9; range, 0 to 9) were significantly higher than scores after placebo administration (median 0.5; range, 0 to 7) and did not differ from scores for the untreated control group. Owner scores indicated capsule administration was easy. Adverse effects (most commonly drowsiness, myorelaxation, and ataxia) resolved ≤ 10 hours after detection. CONCLUSIONS AND CLINICAL RELEVANCE Results suggested oral administration of gabapentin to cats 2 hours before a veterinary visit can reduce FAB during physical examination, enabling more complete evaluation.

OBJECTIVE To evaluate outcomes in cats undergoing subtotal colectomy for the treatment of idiopathic megacolon and to determine whether removal versus nonremoval of the ileocecocolic junction (ICJ) was associated with differences in outcome. ANIMALS 166 client-owned cats. PROCEDURES For this retrospective cohort study, medical records databases of 18 participating veterinary hospitals were searched to identify records of cats with idiopathic megacolon treated by subtotal colectomy from January 2000 to December 2018. Data collection included perioperative and surgical variables, complications, outcome, and owner perception of the procedure. Data were analyzed for associations with outcomes of interest, and Kaplan-Meier survival time analysis was performed. RESULTS Major perioperative complications occurred in 9.9% (15/151) of cats, and 14% (12/87) of cats died as a direct result of treatment or complications of megacolon. The median survival time was not reached. Cats with (vs without) a body condition score < 4/9 (hazard ratio [HR], 5.97), preexisting heart disease (HR, 3.21), major perioperative complications (HR, 27.8), or long-term postoperative liquid feces (HR, 10.4) had greater hazard of shorter survival time. Constipation recurrence occurred in 32% (24/74) of cats at a median time of 344 days and was not associated with retention versus removal of the ICJ; however, ICJ removal was associated with long-term liquid feces (OR, 3.45), and a fair or poor outcome on owner assessment (OR, 3.6). CONCLUSIONS AND CLINICAL RELEVANCE Results indicated that subtotal colectomy was associated with long survival times and a high rate of owner satisfaction. Removal of the ICJ was associated with less favorable outcomes in cats of the present study.

OBJECTIVE To describe the procedure, complications, and long-term outcome of cats that underwent a modified prepubic urethrostomy (mPPU) technique for the management of proximal urethral obstructions. ANIMALS Eight male cats. STUDY DESIGN Short case series. METHODS Medical records were reviewed for signalment, diagnostic investigation, details of the surgical procedure, and complications of cats that underwent mPPU. RESULTS mPPU was well tolerated by all patients, and no intraoperative complications were reported. The duration of follow-up ranged from 13 to 84 months (median 19 months). Early postoperative skin scalding around the stoma associated with mild urinary incontinence during recumbency occurred and was self-limiting in all patients. Two cats required surgical revision at 5 and 6 months, respectively, due to a progressive weight gain and accumulation of abdominal fat around the stoma, causing a partial stomal obstruction. Resolution of clinical signs was reported in both patients. CONCLUSIONS mPPU was easy to perform and offered favorable outcomes in this cohort of cats.

Objectives The aim of this study was to report the use of computed tomography (CT) for postoperative evaluation of the accuracy of sacroiliac reduction and minimally invasive screw fixation in a series of five cats. Methods Medical records between January 2016 and March 2017 of cats presenting to the author's institution were reviewed. Included were cats that had undergone minimally invasive sacroiliac screw fixation with a complete medical record and pre- and postoperative radiographs. Screw size was obtained from the medical records. CT images were acquired prospectively and evaluated to assess joint reduction, relative screw size and screw positioning. Results Six sacroiliac luxations and 6 screws were available. Fixation was achieved with either a 2.4 (n = 1) or 2.7 mm (n = 5), 316L stainless steel, cortical bone screw. Mean screw size as a proportion of sacral diameter was 47.7%. Sacroiliac reduction >90% in the craniocaudal plane and sacral screw purchase >60% of the sacral width were achieved in 3/5 cases. Mean dorsoventral screw angulation was 1.6 degrees (range: −9.7 to 11.7 degrees) and craniocaudal angulation was −4.5 degrees (range: −16.6 to 6.6 degrees). Complications included screw loosening in the one case of bilateral repair and penetration of the neural canal in one case which was not detected with postoperative radiographic evaluation. Clinical Significance CT evaluation provides a useful method for the assessment of sacroiliac reduction and the accuracy of screw placement.

Currently, the interest of veterinarians and owners in the pharmacological correction of situational behavioral disorders in companion animals has increased significantly. To quickly correct deviant behavior in dogs and cats, veterinarians use some of the psychotropic drugs used in humane medicine, in particular, trazodone, an antidepressant antagonist / serotonin reuptake inhibitor. Based on the analysis of literature sources, data on the history of creation and pharmacological properties, assessment of the safety and efficacy of drugs based on trazodone hydrochloride in behavioral medicine of small pets are provided. The data on the prerequisites for the development, pharmaco-toxicological and clinical evaluation of a new drug for the modification of abnormal behavior in dogs and cats, Express Uspokoin® tablets based on trazodone succinate, which, with a high efficiency of the target action, made it possible to achieve the absence of side effects and significantly increase the tolerance of the dosage form by animals, are analyzed. compared with preparations based on trazodone hydrochloride.

Background Increased interest in nutrition by dog and cat owners stresses the importance of providing tailored nutritional guidance for each patient by veterinarians. The World Small Animal Veterinary Association (WSAVA) has provided guidelines to help veterinarians implement this in every‐day patient care, by screening patients for the presence of nutritional risk factors, establishing tailored nutritional plans and providing adequate patient follow‐up tools. Objectives This study aimed to assess the use of nutritional assessments in companion animal practices, and to investigate differences between Dutch and Belgian veterinarians. Methods A survey was conducted among Dutch and Belgian veterinarians. Of the 423 respondents, 53% were from Belgium, and 47% were from the Netherlands. Results Only 21% had prior knowledge of the WSAVA nutritional assessment guidelines. General trends in the usage of nutritional assessments were similar in the examined countries. Aside from weighing, diet evaluation by collecting dietary information and body condition or muscle condition scoring were used infrequently, mostly due to insufficient knowledge of the methods. Nutritional recommendations were often made as part of a treatment plan, and were mostly made by veterinarians, but in Dutch practices also by veterinary nurses. Conclusion Despite the fact that nutritional recommendations are a regular part of treatment plans, nutritional risk factors may be missed due to a lack of completely performed nutritional assessments. It remains important to promote the benefits of regular nutritional assessments to veterinarians, which will improve patients’ health., This study aimed to assess the use of complete nutritional consultation in regular veterinary care. The results of this study show that implementation of nutrition in veterinary care is generally low, and efforts should be made to raise awareness on the benefits of regular nutritional care.

Sporotrichosis is a cosmopolitan subcutaneous mycosis caused by Sporothrix species. Recently, this mycosis has gained notoriety due to the appearance of new endemic areas, recognition of new pathogenic species, changes in epidemiology, occurrence of outbreaks, and increasing numbers of cases. The purpose of this study is to analyze the peculiarities of sporotrichosis cases in Brazil since its first report in the country until 2020. In this work, ecological, epidemiological, clinical, and laboratorial characteristics were compiled. A systematic review of human sporotrichosis diagnosed in Brazil and published up to December 2020 was performed on PubMed/MEDLINE, SciELO, Web of Science, and LILACS databases. Furthermore, animal sporotrichosis and environmental isolation of Sporothrix spp. in Brazil were also evaluated. The study included 230 papers, resulting in 10,400 human patients. Their ages ranged from 5 months to 92 years old and 55.98% were female. The lymphocutaneous form was predominant (56.14%), but systemic involvement was also notably reported (14.34%), especially in the lungs. Besides, hypersensitivity manifestations (4.55%) were described. Most patients had the diagnosis confirmed by isolation of Sporothrix spp., mainly from skin samples. Sporothrix brasiliensis was the major agent identified. HIV infection, cardiovascular diseases, and diabetes were the most common comorbidities. Cure rate was 85.83%. Concerning animal sporotrichosis, 8538 cases were reported, mostly in cats (90.77%). Moreover, 13 Sporothrix spp. environmental strains were reported. This review highlights the burden of the emergent zoonotic sporotrichosis in Brazil, reinforcing the importance of “One Health” based actions to help controlling this disease.

OBJECTIVES To determine the prevalence of stress hyperglycaemia in sick cats, and to investigate the association of stress hyperglycaemia with systemic inflammatory response syndrome and outcome. MATERIALS AND METHODS Medical records (2004 to 2013) from sick cats admitted to the Medicine Unit of a Veterinary Teaching Hospital were retrospectively reviewed. Cases were enrolled if a serum glucose measurement and a complete medical record were available. Cats that were healthy, hypoglycaemic, diabetic, sedated or had a previous administration of drugs (apart from vaccination and deworming) were excluded. RESULTS The study included 647 cats; stress hyperglycaemia (serum glucose >8.3 mmol/L) was found in 194 (30%) cats, while 453 (70%) cats were normoglycaemic. The prevalence of systemic inflammatory response syndrome was significantly higher in cats with stress hyperglycaemia (25/174, 14.4%) compared to normoglycaemic cats (26/399, 6.5%). Significantly, more cats with stress hyperglycaemia were hospitalised [97/194 (50.0%)] compared to normoglycaemic cats [171/453 (37.7%)]. However, the median duration of hospitalisation was not significantly different [4 (1 to 26) days and 4 (1 to 24) days, respectively]. The prevalence of cats with negative outcome was not significantly different between the two groups (cats with stress hyperglycaemia: 37.1%, normoglycaemic cats: 33.9%). Nonetheless, when modelling of outcome prediction included breed, age, stress hyperglycaemia and disease category as factors, cats with stress hyperglycaemia had 2.8 times the odds to have a negative outcome (95% confidence interval: 1.3 to 6.4). CLINICAL SIGNIFICANCE Based on the cut-off employed in this study, Stress hyperglycaemia, as defined by the cut-off is common in sick cats. Stress hyperglycaemia is associated with systemic inflammatory response syndrome development and seem to be a negative prognostic indicator.

OBJECTIVE To gather and evaluate veterinarians' perspectives about the impacts of the COVID-19 pandemic on the use of veterinary telehealth and on cat owners' versus dog owners' attitudes toward transmission of the SARS-CoV-2 virus from their pets. SAMPLE 93 respondent veterinarians (47 in primary care practice and 46 in specialty practice). PROCEDURES An online survey was conducted between June 15 and July 15, 2020, and included 21 questions concerning demographics, use of telehealth before and after the onset of the pandemic (before March 15, 2020, and between March 15 and June 15, 2020, respectively), changes in caseloads, and perception of clients' concerns about potential for transmission of the SARS-CoV-2 virus from pets. Reported zip codes informed the collection of census data. RESULTS The level of poverty was significantly lower in zip code areas for respondents who reported telehealth services were (vs were not) offered before the pandemic. The percentage of respondents who reported their practice offered telehealth services increased from 12% (11/93) before the pandemic to 38% (35/93) between March 15 and June 15, 2020. Although most respondents reported owner-expressed concerns over SARS-CoV-2 virus transmission from their pets, most also reported increased caseloads, seeing newly adopted pets, and few discussions of surrender of pets for reasons related to the SARS-CoV-2 virus. CONCLUSIONS AND CLINICAL RELEVANCE Findings indicated that caseloads increased and telehealth services expanded during the pandemic but that there was no evidence of differences in respondent-reported owner concern for SARS-CoV-2 virus transmission from cats versus dogs.

CASE DESCRIPTION During the same week, 3 sequential patients (a 10-year-old 8.7-kg spayed female poodle cross [dog 1], 13-year-old 2.6-kg spayed female domestic longhair cat, and 13-year-old 9.0-kg castrated male mixed-breed dog [dog 2]) underwent CT-angiography (day 0) and transarterial embolization (day 1) for nonresectable hepatocellular carcinoma (n = 2) or prostatic carcinoma (1). CLINICAL FINDINGS Contrast-induced nephropathy (CIN) was suspected in all animals on the basis of higher serum creatinine concentrations after contrast medium administration (exposure), compared with baseline concentrations before exposure, consistent with CIN definitions. The total dose of contrast medium was < 3 mL/kg for each exposure. For all 3 patients, creatinine concentration peaked at a median of 3 days (range, 2 to 3 days) after the first exposure (day 0), and the median absolute and relative increases in creatinine concentration after exposure (vs baseline concentrations before exposure) were 2.9 mg/dL (range, 2.2 to 3.7 mg/dL) and 410% (range, 260 to 720%), respectively. TREATMENT AND OUTCOME The patients received individually tailored supportive care for acute kidney injury. Serum creatinine concentrations began to improve at a median of 4 days (range, 3 to 4 days) and returned to within reference limits at a median of 7 days (range, 3 to 13 days) following initial exposure. CLINICAL RELEVANCE CIN should be considered as a potential complication following IV administration of contrast medium. Short-term outcome following CIN can be excellent with supportive care.

This report describes periarticular plasma cell tumors with abundant amyloid in 11 cats. The tarsus was the most commonly affected joint (10/11), and the masses were often circumferential around the tarsal joint, involving the dermis and subcutis. The 2 cases in which synovium was examined had neoplastic cells expanding the synovium. Three of the 5 cases staged radiographically had bony lysis of the affected joint. Cutaneous biopsy specimens often consisted of more amyloid than plasma cells, making the diagnosis difficult on small samples. Follow-up information was available in 7 cases; in those cases, the median survival was 194 days (range 53–671 days). Four cases had confirmed metastases, most often to regional lymph nodes, liver, and spleen. Although canine cutaneous plasma cell tumors are typically benign, those with abundant amyloid surrounding the joints of cats may involve deeper tissues and have a more aggressive behavior. These tumors can be difficult to diagnose due to low cellularity and abundant amyloid.

OBJECTIVE The objective of this study was to determine the repellency and efficacy of a 10% imidacloprid/4.5% flumethrin (Seresto® , Elanco) collar over an 8-month period against the eastern paralysis tick (Ixodes holocyclus) on cats. METHODS Two non-blinded, open gender, randomised, placebo-controlled pen studies were conducted, with 26 cats enrolled in each study. Prior to inclusion, cats were immunised with I. holocyclus holocyclotoxin. Cats were treated on Day 0 with either an imidacloprid/flumethrin or placebo collar. Tick infestations with 20 unfed adult female eastern paralysis ticks commenced on Day 7, and were repeated monthly for 8 months. Repellency was determined by comparing the mean number of attached ticks on imidacloprid/flumethrin treated cats, to placebo collar treated cats at 6 and 24 h post infestation. Efficacy was determined by comparing the mean number of live ticks on imidacloprid/flumethrin collar treated cats to placebo collar treated cats at 72 h post infestation. RESULTS Efficacy was 100% (P

Background Multimodal analgesia consists of the combination of analgesic drugs at low doses to act in different places along the path of pain. Studies with continuous infusion of analgesic drugs in cats are not common. This study aimed to evaluate the analgesic effect of maropitant, lidocaine and ketamine alone or in combination (intravenous bolus + subsequent continuous intravenous infusion) in the management of acute postoperative pain in cats undergoing ovariohysterectomy. Seventy healthy cats undergoing an ovariohysterectomy received a standard anesthetic protocol consisting of acepromazine and morphine, propofol (anesthesia induction), and isoflurane (anesthesia maintenance). The animals were stratified into seven groups (n = 10 in each group): control (CG), maropitant (MG), lidocaine (LG), ketamine (KG), maropitant + lidocaine (LMG), maropitant + ketamine (KMG), and maropitant + lidocaine + ketamine (LKMG). All drugs were injected first as an intravenous bolus and then by continuous intravenous infusion. During surgery, esophageal temperature, respiratory rate, heart rate, oxygen saturation, expired isoflurane concentration, and partial pressure of carbon dioxide at the end of expiration were evaluated at 7 time points. Postoperative pain was evaluated for 6 h after extubation using the visual analogue scale and the UNESP-Botucatu multidimensional composite pain scale for assessing postoperative pain in cats. Results Adverse effects related to maropitant, lidocaine and ketamine infusion were not observed. Pain scores were lower in the MG, KG and LG groups when compared to the CG group using both scales. Although pain scores were also lower in all combination groups than CG, more animals in these groups required rescue analgesia compared to MG. This indicates that the postoperative analgesic effect of all drugs, either alone or in combination, confers analgesia, although the combinations did not promote greater analgesia. Conclusions Continuous intravenous infusion of maropitant, lidocaine, and ketamine alone induces postoperative analgesic effect in cats undergoing ovariohysterectomy, but combinations of these drugs did not increase the analgesic effect. No adverse effect was observed with any drug or their combination.

Heart disease is a common cause of morbidity and mortality in cats. Focused cardiac ultrasonography (FCU) is a useful diagnostic tool for identifying heart disease in symptomatic and asymptomatic cats when performed by trained veterinarians. When used in conjunction with other diagnostics such as physical examination, blood biomarkers, electrocardiography, Global FAST, and other point-of-care ultrasonographic examinations, FCU may improve clinical decision making and help clinicians prioritize which cats would benefit from referral for complete echocardiography and cardiac consultation. This article reviews the definition, advantages, clinical indications, limitations, training recommendations, and a protocol for FCU in cats.

OBJECTIVE To establish a pathoepidemiological model to evaluate the role of SARS-CoV-2 infection in the first 10 companion animals that died while infected with SARS-CoV-2 in the US. ANIMALS 10 cats and dogs that tested positive for SARS-CoV-2 and died or were euthanized in the US between March 2020 and January 2021. PROCEDURES A standardized algorithm was developed to direct case investigations, determine the necessity of certain diagnostic procedures, and evaluate the role, if any, that SARS-CoV-2 infection played in the animals’ course of disease and death. Using clinical and diagnostic information collected by state animal health officials, state public health veterinarians, and other state and local partners, this algorithm was applied to each animal case. RESULTS SARS-CoV-2 was an incidental finding in 8 animals, was suspected to have contributed to the severity of clinical signs leading to euthanasia in 1 dog, and was the primary reason for death for 1 cat. CONCLUSIONS AND CLINICAL RELEVANCE This report provides the global community with a standardized process for directing case investigations, determining the necessity of certain diagnostic procedures, and determining the clinical significance of SARS-CoV-2 infections in animals with fatal outcomes and provides evidence that SARS-CoV-2 can, in rare circumstances, cause or contribute to death in pets.

Objective To determine biomarkers for impending fluid overload during intravenous fluid administration in a feline haemorrhage-resuscitation model. Study design Randomized crossover study. Animals A group of six domestic cats (mean age and weight: 21 months; 4.9 kg, respectively). Methods The cats underwent three treatments, 2 months apart. They were anaesthetized and instrumented to measure a range of physiological, blood gas, haematological and biochemical variables over time. Samples were taken during a health check, before haemorrhage, after haemorrhage and then at 30 minute intervals during fluid resuscitation and 24 hours later. The three treatments were: 1) control, sham haemorrhage and resuscitation; 2) lactated Ringer’s solution (LRS); and 3) 6% tetrastarch 130/0.4 (Vol) where the cats underwent a controlled haemorrhage then resuscitation by administering LRS and Vol at 60 and 20 mL kg–1 hour–1, respectively, for 120 minutes. Fluid overload was identified by nasal discharge and radiographic evidence. Biomarkers were variables that exceeded the reference interval for cats during treatment. Potential biomarkers were analysed using receiver operating characteristic curves (p Results Mean ± standard deviation total blood loss was 10.2 ± 2.3, 29.3 ± 9.0 and 29.1 ± 6.3 mL kg–1 for control, LRS and Vol, respectively. The total volume of LRS and Vol administered was 120 and 40 mL kg–1, respectively. Haematocrit, albumin, magnesium, chloride-to-sodium ratio and sodium-chloride difference were identified as potential biomarkers. These variables exceeded the reference intervals from 30 minutes of resuscitation onwards. A chloride-to-sodium ratio > 0.84 was the most sensitive (90%) and specific (75%) of all potential biomarkers. Conclusions and clinical relevance Changes in physiological variables, haematocrit and albumin were poor biomarkers of impending fluid overload compared with electrolytes. Finding the ideal biomarker to identify impending fluid overload of commonly used intravenous fluids should improve the safety of their administration in cats.

Summary A 15-year-old male white Siberian tiger (Panthera tigris altaica) was evaluated for an elevated, ulcerated, cutaneous mass on the right flank. The mass was removed by excisional biopsy and submitted for histopathology. Based on distinct histological features of intracytoplasmic globular material and positive immunohistochemical staining for Melan-A and vimentin, an amelanotic signet-ring melanoma was diagnosed. While in domestic cats this neoplasm is associated with malignancy and a short survival time, the tiger had no local recurrence or related clinical disease approximately 4 years post surgery. Cutaneous melanocytic tumours are rare in big cats, and the findings in this case suggest that amelanotic signet-ring melanoma is not as malignant as its counterpart in domestic cats.

Background Cats with moderate to advanced chronic kidney disease (CKD) often display clinical signs such as vomiting and decreased appetite, and frequently receive omeprazole or other acid suppressants despite a lack of evidence to support their use. Hypothesis/objectives To evaluate the effect of once-daily PO omeprazole on appetite in cats with CKD. We hypothesized that omeprazole would improve subjective appetite assessments in cats with CKD. Animals Fourteen client-owned cats with International Renal Interest Society (IRIS) stage 2 or 3 CKD and hyporexia. Methods Cats were prospectively enrolled in a multi-institutional, double-blinded, randomized, crossover study to evaluate the effect of a 14-day trial of once-daily PO omeprazole (1 mg/kg) or placebo (lactose gel capsule) on vomiting frequency and appetite. A daily log was completed by the owner during all treatment and rest periods to assess appetite using a subjective, qualitative, and 5-point scoring system. Mixed model analyses of variance were performed to determine if average daily percentage food consumed or appetite score, as measured by subjective owner assessment, differed between treatments. Results Compared to placebo, a negligible but statistically significant difference in percentage of food consumed was observed between treatments (P = .04) with once-daily omeprazole treatment resulting in a 2.7% increase in food consumption compared to placebo. No significant difference, however, was found in appetite score, body weight, or serum creatinine concentration between treatments. Conclusions and clinical importance Once-daily omeprazole does not markedly increase appetite in cats with CKD and should not be used as a first-line treatment in the absence of evidence of gastrointestinal ulceration.

Point-of-care ultrasonography as part of the physical examination is becoming considered a core skill. AFAST includes 5 acoustic windows over the abdomen and serves as a rapid screening test for free fluid (ascites, retroperitoneal, pleural and pericardial effusion) and soft tissue abnormalities (target-organ approach), and has an abdominal fluid scoring system (semiquantitating volume). Moreover, add-on skills are possible without additional views that include characterizing the caudal vena cava and hepatic veins (volume status), measuring the urinary bladder (volume estimation and urine output), screening for free air (pneumoperitoneum, pneumoretroperitoneum), and assessing gastrointestinal motility.

Thirty-three fecal samples from cats were examined for the presence of Toxoplasma oocysts, and another 33 serum samples from these cats were subjected for Latex agglutination test & indirect immunofluorecent antibody test. Also 80 serum samples from ewes were subjected to the same serological tests. The study indicated that the prevalence of Toxoplasma oocysts in cats was 27.3%. Higher rates of antibody titer (68%) were observed in cats tested with latex test. Infection in young cats was higher than in adults. Sixty percentage of ewes were sero-positive with Latex test, but only 35% were sero-positive with IFAT, higher prevalence of antibody titers was observed in sheep from the three locations of Iraq. Ewes that had recurrent abortion showed higher prevalence in both tests than non aborted ewes.

Soft tissue swellings, masses, and fluid collections commonly occur in small animal patients and can be the main reason for the clinical examination of the patient or an incidental finding. Several of these masses are likely benign or nonneoplastic, and ultrasound can help further evaluate these lesions to guide treatment planning. Careful attention to optimizing the ultrasound technique and Doppler settings is necessary to ensure that the vascularization of a mass is assessed correctly.

Summary In humans, atypical endometrial hyperplasia (AEH) is considered as a precancerous lesion of endometrial adenocarcinoma (EA), from which it must be distinguished. Precancerous lesions have not been reported in cats with EA. We now document the histopathological features of endometrial lesions in six cats, which histopathologically resembled human AEH and had a good prognosis following ovariohysterectomy. Grossly, one cat presented with papillomatous nodules and three cats had pyometra. Histopathologically, proliferation of endometrial epithelial cells without atypia was observed in all cases. In some regions of the endometrium, cells had increased atypia and were arranged in stratified layers, which formed irregular ducts and papillary structures. No invasive behaviour or vascular invasion was observed. On the basis of these findings, the cats were diagnosed with non-invasive or early-stage adenocarcinoma. Immunohistochemistry for oestrogen receptor and progesterone receptor revealed an inverse correlation with the severity of the endometrial lesions and degree of malignancy of tumour cells. Ki67 labelling revealed that mitotic activity increased as the lesion developed. All cats survived, with a median survival time of 385 days (range: 229–744 days). The distribution of the histopathological endometrial changes and the non-invasive behaviour in these feline cases resemble cases of AEH in humans.

Purpose The present study compared the expression of early growth responsive gene-1 (Egr-1) in visual cortex between amblyopia kittens and normal kittens, and to explore the role of Egr-1 in the pathogenesis of amblyopia. Methods A total of 20 healthy kittens were randomly divided into deprivation group and control group with 10 kittens in each group. Raised in natural light, and covered the right eye of the deprived kittens with a black opaque covering cloth. Pattern visual evoked potentials (PVEP) were measured before and at the 1st, 3rd and 5th week after covering in all kittens. After the last PVEP test, all kittens were killed. The expression of Egr-1 in the visual cortex of the two groups was compared by immunohistochemistry and in situ hybridization. Results PVEP detection showed that at the age of 6 and 8 weeks, the P100 wave latency in the right eye of deprivation group was higher than that in the left eye of deprivation group (P P P P P P P Conclusions Monocular form deprivation amblyopia can lead to the decrease of Egr-1 protein and mRNA expression in visual cortex, and then promote the occurrence and development of amblyopia.

Background Frunevetmab, a felinized antinerve growth factor monoclonal antibody, effectively decreases osteoarthritis (OA) pain in cats. Objective To evaluate the efficacy of frunevetmab given at monthly intervals in a randomized, placebo-controlled, parallel-group, double-blind superiority study. Animals Two hundred seventy-five client-owned cats with naturally-occurring OA pain and associated mobility impairment and disability. Methods Randomized, placebo-controlled, parallel-group, double-blind, superiority study. Following screening, cats received frunevetmab (nominal dose of 1.0 mg/kg, SC [effective dose range of 1.0-2.8 mg/kg]) or placebo on days 0, 28, and 56. Outcome measures were owner questionnaires and veterinary physical and orthopedic evaluations at days 28, 56, and 84. Success/failure rates (and numbers needed treat, NNT) and change in scores (and standardized effect size, ES) were analyzed. Results Frunevetmab (182) and placebo (93) treated cats were enrolled and received at least 1 treatment. Significant improvement with frunevetmab over placebo occurred at days 28 and 56 for the client specific outcome measures (CSOM) questionnaire (success rates and total scores [NNT of 9 and ES of 0.3 at day 56]); at days 28 and 56 for owner-assessed global treatment response; and at days 56 and 84 for veterinarian-assessed joint pain (ES of 0.18 at day 56). Adverse events did not differ between groups, except skin disorders which collectively occurred significantly more frequently in frunevetmab treated (32/182 cats) vs placebo (8/93 cats). Conclusions and clinical importance Frunevetmab has the potential to address a critical gap in the treatment of pain because of osteoarthritis in cats.

Objective To evaluate the anaesthetist’s ability to predict abnormalities in preanaesthetic blood test results obtained from cats and dogs older than 8 years and to describe the impact of these preanaesthetic blood test results on the American Society Anesthesiologists (ASA) physical status classification, anaesthetic protocol and procedures. Study design Observational, prospective, clinical multi-centre study. Animals A total of 333 cats and dogs. Methods After a clinical examination and review of the animal´s clinical history the anaesthetist completed the first part of a set of questions including ASA status and anticipated abnormalities in blood tests. After this, blood results were presented, and the anaesthetist completed the second part of the set of questions, including changes in ASA status or anaesthetic protocol, and procedure delay or cancellation. Preanaesthetic blood tests included: haematocrit, total proteins, electrolytes, glucose, lactate, urea and creatinine. Examiners were classified as senior clinicians, clinicians, anaesthesia residents or nurses, and interns. For statistical analysis, the chi-square test was used. A p value Results The ASA status increased in three dogs and one cat (1.2%); in two of them abnormalities were not expected by the examiner. The anaesthetic protocol changed in seven animals (2.1%); the most common change related to fluid therapy. Anaesthesia was delayed in two dogs (0.6%) to administer intravenous fluid therapy. No cases were cancelled. Abnormalities were more commonly found [37 out of 58 assessments (approximately 64%)] when the anaesthetist predicted them compared to when they were unexpected [49 of 275 assessments (approximately 18%); p Conclusions and clinical relevance Routine non-targeted blood tests in cats and dogs older than 8 years led to few changes in the anaesthetic management, and anaesthetists correctly predicted blood test results in most cases.

Buprenorphine, an analgesic commonly used in rodent surgery, requires repeated dosing every 4 to 6 h in order to provide adequate analgesia. However, redosing requires repeated handling, which may itself cause stress. Buprenorphine SR-LAB, which reportedly maintains serum levels of buprenorphine greater than 1 ng/mL for 48 to 72 h, is commercially available. However, the viscosity of the product and small dosing volumes make accurate dosing a challenge. Simbadol is a concentrated formulation of buprenorphine hydrochloride labeled for use in cats with recommended dosing frequency of every 24 h. We measured serum concentrations over time after a single injection of this product in C57BL/6NCrl mice and compared it to standard buprenorphine (Buprenex) and Buprenorphine SR-LAB. Male and female mice were injected subcutaneously with one of the 3 buprenorphine formulations at a dose of 1 mg/kg at time 0. Groups of mice (n = 8) were euthanized at 1, 4, 8, 12, 16 h for all groups and 24 h for the Simbadol and the Buprenorphine SR-LAB. Liquid chromatography-mass spectrometry (LC-MS/MS) was used to determine concentrations of buprenorphine in each serum sample. High concentrations were observed in both Simbadol and standard buprenorphine groups one hour after injection (>50 ng/mL). These groups had similar buprenorphine concentration curves, including rates of decline. The standard buprenorphine group had mean concentrations less than 1 ng/mL by 12 h and the Simbadol group by 16 h. In contrast, the Buprenorphine SR-LAB group remained above the 1 ng/mL therapeutic threshold throughout the 24 h. In addition, clinical signs, including increased activity, that lasted for up to an hour after the injection in the Simbadol and standard buprenorphine groups. We conclude that Simbadol does not offer dosing advantages over the standard buprenorphine formulation when given at 1 mg/kg. Buprenorphine SR-LAB maintained a steady concentration of buprenorphine above 1 ng/mL for at least 24 h, and as such is a superior choice for providing long-term analgesia.

Two dogs and 1 cat were referred to a tertiary veterinary center for the consultation and treatment of limb edema, variable dermal sanguineous crusting lesions, and intermittent lameness. A peripheral arteriovenous anomaly (PAA) was diagnosed via computed tomographic angiography (CTA) in each case. Arteriography enabled further evaluation of the PAA with confirmation of a dominant outflow vein. Dominant outflow vein occlusion was achieved by direct ligation in 1 dog and retrograde transvenous glue embolization in the cat and other dog. Repeat arteriography demonstrated resolution of arteriovenous shunting. Presenting clinical signs resolved in all animals. The previously identified aberrant vessels in 1 dog were not identified after CTA 40 days postoperatively. No postoperative complications or recurrence was identified in any case during the 6‐ to 55‐month follow‐up period.

In small animals, point-of-care ultrasound can be used by nonradiologist sonographers to identify thrombosis at several anatomic sites. Dogs and cats are well-suited for vascular interrogation using ultrasound because of their small body size. Ultrasound can be used to investigate targeted vessels based on clinical signs. The safety and tolerability of the examination makes this a useful modality to evaluate critical patients for evidence thromboembolic disease. Once vascular imaging techniques are learned they can be easily coupled with other point-of-care examinations such as focused cardiac ultrasound, Vet Blue, AFAST, and TFAST.

Summary Pneumonia in cats may cause severe lung injury and consequent death. We describe the post-mortem findings and aetiologies of naturally fatal pneumonia in 78 domestic cats, using gross and histopathological examinations, immunohistochemistry and microbiological techniques. Morphological patterns found were bronchopneumonia (27/78), interstitial (15/78), bronchointerstitial (13/78), granulomatous (8/78), aspiration (8/78) and pyogranulomatous (5/78) pneumonia, and pleuropneumonia (2/78). Bacterial pneumonia was identified as the most common cause (32/78), followed by viral (15/28 feline calicivirus, 10/28 felid alphaherpesvirus 1 and 3/28 both viruses), aspiration (8/78), fungal (5/78) and parasitic pneumonia (5/78). Co-infection with feline immunodeficiency virus and feline leukaemia virus was found in 54 cats. Viral infections involved cats of all ages, indicating the importance of investigating viral causes in cats with respiratory diseases, including in adult and ageing cats.
