Types of Allergies in Cats
There are 4 common allergies in cats: environmental, fleas, food, and seasonal. This section elaborates on these types of allergies and the different ways in which they may affect your cat.
Environmental Allergies - The cause of environmental allergies include pollen, grass, fungi, mold, and dust. Your cat may also have allergies to things like cigarette smoke, perfume, and certain types of cleaning products.
Flea Allergies - When a small external parasite known as a flea bites your cat, it causes an allergic reaction that can be very irritating. The saliva from a flea bite can affect a cat’s entire body, not just where the cat was bitten. Your veterinarian can help you choose the right flea-prevention product to help protect your cat.
Food Allergies - Some cats may have allergies to certain foods. This can cause skin itchiness, vomiting, or diarrhea. Your veterinarian can help you find out which foods are irritating your cat and create an appropriate diet.
Atopic Dermatitis - When a cat experiences allergies, their bodies can often react with a skin condition called atopic dermatitis. With this condition, your cat may develop skin sores, scabbing, hair loss, and redness.
How Are Allergies in Cats Diagnosed?
If your cat is itching, scratching, and wheezing your vet will likely want to complete a thorough physical exam and discuss your cat's medical history. They will also recommend laboratory testing to be sure of your cat's diagnosis.
Cat allergy testing is done with either a blood test or a skin test. For a blood test, the vet will take a sample of the cat’s blood and send it to a lab for evaluation. For a skin test, small injections are given to the cat just under the skin. If your cat is allergic to a particular substance, a hive will often appear on their body.
Veterinary Allergy Medicine for Cats
Veterinarians take a multi-faceted approach to treating pet allergies. They will start by treating the clinical signs such as excessive itchiness and secondary bacterial or yeast skin or ear infections.
Depending on the allergen, and the reaction it causes, treatment can include:
- Prescription shampoo (antibacterial or antifungal)
- Prescription ear flushes
- Anti-inflammatory topical medications
- Oral antibiotics
- Itch relief medication, such as Apoquel for dog allergies or Atopica for cats
- Injectable monoclonal antibody therapy

If your pet has mild seasonal allergies without a skin infection, over-the-counter antihistamines might be an option for allergy relief. Benadryl, Zyrtec, and Claritin are commonly used allergy medicine for pets. always contact your vet before giving your pet over-the-counter medication to ensure the medication and dosage are safe for your cat.
