Louse infestation (pediculosis) in pet animals

Although pediculosis in pet animals is less common than flea infestation in most parts of the United Kingdom, it should be considered in the differential diagnosis of pruritus, erythema, scaling, anaemia and irritability. It is a cause of miliary dermatitis in cats. Lice are easily killed by many commercially available insecticides. Transmission is usually by direct contact but indirect transmission is also possible and brushes, combs, bedding and the general environment should be kept clean.
