This article explores the nutritional needs and health outcomes of ageing cats and dogs. It discusses the lack of explicit nutritional guidelines for feeding ageing animals and emphasizes the importance of increased scientific knowledge in this area. The article also highlights the differences in nutrient requirements between cats and dogs and the impact of dietary format on their health. It discusses the role of the gut microbiome in ageing and calls for updated nutrient guidelines that consider the unique nutritional requirements of ageing cats and dogs. The article also discusses the mechanisms of aging in cats and dogs, the effects of diet on their aging process, and the lack of specific nutritional guidelines for senior pets. It mentions the need for further research to understand the aging process in cats and dogs and develop targeted dietary interventions to improve their healthspan. The article provides a table summarizing nutrients that have been proven to be effective in improving certain aspects of cats' and dogs' health. It also discusses the health concerns affecting senior pets, such as sarcopenia, inflammageing, and cognitive function. The article concludes by emphasizing the need for further research to understand the specific nutrient requirements of aging cats and dogs and develop nutritional guidelines for them.

In a world of the "Three Rs" (replace, reduce and refine), combined with more research published via open access research journals, there is increasing interest in the statistical analysis of existing literature. Metaanalysis - the combination of multiple studies, can be used to get better oversight into a specific question of interest. Additionally, it can be used to identify gaps in knowledge. For example, while there are a number of publications investigating energy requirements in adult cat and dog, few studies assess older animals. Similarly, in the dog, there is a lack of literature around dogs at the extremes of body size (i.e. giant and toy breeds). Herein, we describe several published examples that have been used to determine energy requirements of cats and dogs, and more recently, the impacts of diet on the microbiome of the cat and dog. This includes the use of Preferred Reporting Items for Systematic reviews and Meta-Analyses (PRISMA) guidelines, research findings and general findings related to research design and quality.

Background: Flexitarian, vegetarian and exclusively plant-based diets are increasingly popular, particularly amongst young adults. This is the first randomised dietary intervention to investigate the health, wellbeing, and behavioural implications of consuming a basal vegetarian diet that additionally includes low-to-moderate amounts of red meat (flexitarian) compared to one containing plant-based meat alternatives (PBMAs, vegetarian) in young adults (ClinicalTrials.gov NCT04869163). The objective for the current analysis is to measure adherence to the intervention, nutrition behaviours, and participants' experience with their allocated dietary group., Methods: Eighty healthy young adults participated in this 10-week dietary intervention as household pairs. Household pairs were randomised to receive either approximately three serves of red meat (average of 390 g cooked weight per individual, flexitarian group) or PBMAs (350-400 g per individual, vegetarian group) per week on top of a basal vegetarian diet. Participants were supported to adopt healthy eating behaviours, and this intervention was developed and implemented using a behaviour change framework. Adherence (eating allocated red meat or PBMA, abstaining from animal-based foods not provided by researchers) was continuously monitored, with total scores calculated at the end of the 10-week intervention period. Eating experiences were measured by the Positive Eating Scale and a purpose-designed exit survey, and a food frequency questionnaire measured dietary intake. Analyses used mixed effects modeling taking household clustering into account., Results: The total average adherence score was 91.5 (SD = 9.0) out of a possible 100, with participants in the flexitarian group scoring higher (96.1, SD = 4.6, compared to 86.7, SD = 10.0; p  < 0.001). Those receiving red meat were generally more satisfied with this allocation compared to those receiving the PBMAs, even though a leading motivation for participants joining the study was an opportunity to try plant-based eating (35% expressed that their interest in taking part was related to trying plant-based eating). Participants in both intervention groups had increased vegetable intake ( p  < 0.001), and reported more positive eating experiences ( p  = 0.020) and satisfaction with eating ( p  = 0.021) at the end of the 10-week intervention relative to baseline values., Conclusion: Methods to encourage engagement with the trial were successful, as participants demonstrated excellent adherence to the intervention. Observed differences in participants' adherence and experiences between flexitarian and vegetarian groups holds implications for the adoption of healthy, sustainable dietary patterns beyond this study alone., Competing Interests: The authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest., (Copyright © 2023 Gillies, Worthington, Li, Conner, Bermingham, Knowles, Cameron-Smith, Hannaford and Braakhuis.)
