Cats and Allergies

Is your cat suffering from allergies? Has your cat been sneezing or showing other signs of irritation? She may be having reactions to her food or her environment. 

Environmental Contaminants

Environmental contaminants, such as dust and mold, can cause allergies in a cat. If your cat is sneezing over and over again over the course of several days, contact a veterinarian to have her checked out. 

Food Allergies

Food can also cause allergies, although it takes time to make that diagnosis. Usually veterinarians will put a cat on a food elimination diet to determine if she has a food allergy. That means the cat spends eight to ten weeks on a special hypoallergenic diet. If her clinical signs improve on the hypoallergenic diet, she is then challenged with her original diet. 

Clinical Signs of Allergies

If the cat is truly allergic to a particular food, there will likely be an increase in clinical signs, such as itching and inflamed skin. If these appear, further testing will be needed to determine which specific ingredients trigger the allergy symptoms.

We offer cat foods that can help with a variety of allergy problems. We hope this information helps you improve your cat’s health.
