Like people, cats can suffer from allergies.
As in the human population, the incidence of allergies in pets seems to be increasing. While allergic humans may often sneeze, wheeze or even have serious respiratory difficulties, allergic reactions in pets are characterized by skin problems, exacerbated by their primary symptom – itching and scratching. Cat allergies fall into three main categories: flea allergy dermatitis, atopy, and food allergy. Many pets can be affected by one or more allergy.
