Visit your Vet. After taking a complete history and conducting a physical examination, your veterinarian may determine the source of your cat’s allergic reaction. If not, she or he will most probably recommend skin or blood tests and/or a special elimination diet, to find out what’s causing the allergic reaction.

Also bathing your cat one or two times per week regularly may help relieve itching and remove environmental allergens and pollens from her skin; talk to your veterinarian for a shampoo recommendation, as frequent bathing can also dry out skin.

Fatty acid supplements might help relieve your cat’s itchy skin. There are many shampoos that may help prevent skin infection, which occurs commonly in cats with allergies. Sprays containing oatmeal, aloe and other natural products are also available.
