Cat Allergy

"Cat allergy is caused by allergens in the air, food, medications or insects such as fleas. Treatment begins with identifying the underlying cause and then eliminating the irritant. Most feline allergies affect the skin."


Cat allergy is very common with about 15% having some type of allergy. Allergic reactions in cats are different than what happens in people. In humans, allergies usually cause problems with breathing. In cats, allergies usually affect the skin and cause itching.

Causes of Cat Allergy

There are several causes of feline allergy, including:

Insects – Fleas (this is the most common allergy called Flea allergy dermatitis) and other biting insects. The saliva in the fleas’ mouth causes flea allergies. A typical flea allergic reaction will have your cat itching the moment they come in contact with the fleas with the itch continuing even after the fleas are killed.

Airborne Allergens – Pollen, grass, and mold (feline atopic dermatitis)

Food and Drugs – Certain foods and medications, including vaccinations (food allergies are called Cutaneous adverse food reactions).

Symptoms of Cat Allergy

Allergic reactions in cats can either happen immediately after exposure to an allergen (something that causes an allergic reaction) or can be from a delayed reaction to an allergen.

Constant licking of paws is a common symptom of allergies, more so than a stuffy nose. Other common symptoms to allergy include face-rubbing, belly-licking and ear infections. Coughing, sneezing, nasal and eye discharge, and difficulty breathing may also occur, however.Feline Hives

Immediate allergic reactions (within 30 minutes) usually cause feline hives on the skin. They can appear anywhere and usually disappear in 24 hours. You can recognize hives by a raised appearance, circular shape and itch. Your cat’s hair may also be raised in patches.

Hives are most often caused by insect bites, drug allergy (after vaccination common cause), insecticides (lawn treatments), and new foods.

Treatment of Cat Hives from Allergy

Hives disappear once the cause is no longer in contact with your cat. Determine what has changed in the past several hours such as a new food or if your cat was around a new substance such as a new brand of kitty litter.

For food allergies you can give your cat Milk of Magnesia (consult your Veterinarian first, suggested dose 7 to 25 ml. per pound orally once only) that quickens removal of the food from your cat’s stomach. If hives are caused by insecticide or other substance that came in contact with your cat’s skin, give your cat a bath using products you know are safe.

Like humans, you can also give your cat Benadryl (2 mg per pound orally every eight hours). Talk to your vet before giving your cat the medication to make sure it is safe for your cat. For extreme cases your veterinarian may also prescribe cortisone treatments.
