Atopic dermatitis (atopy) is a skin problem caused by an allergy to something in the environment (such as pollen, moulds, grass or dust mite).
Cats with atopy tend to have extremely itchy skin that is usually worst on the head, neck, sides, tummy, armpits and inner thighs. Constant scratching, licking and biting makes their skin red, sore and open to infection.
Atopy is an uncommon condition in cats so your vet will want to rule out common causes of itchy skin before diagnosing it.
Treatment for atopy often includes a special diet, medication to stop the itch and skin supplements. Without treatment, atopy can severely affect a cat’s quality of life but with proper treatment, cats with atopy can live a long, happy life.
