Like people, cats can suffer from allergies.
The incidence of allergies for cats seems to be increasing. While human allergy symptoms may include sneezing, wheezing or even 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.
