Cat Food Allergies and Intollernce


Food allergies in cats are the result of an over-reaction of the immune system in response to an antigen in food. As humans, it is not known why some cats suffer from allergies and others don’t. Cats cannot develop a food allergy unless they have been exposed to the food first and allergies can occur at any time during your male or female cat’s life. Using a hypoallergenic cat food is one way in which you could eliminate or reduce your cat’s food allergy symptoms.

Food Allergy vs Food Intolerance?

Consumers can often misunderstand food intolerance as an allergy because both can produce similar symptoms.  

A cat that has a food allergy will often have prolonged itchy skin affecting the head, stomach, groin, armpits, legs, and paws. This will usually result in over-grooming, causing additional wounds and hair loss later on. Other symptoms can include vomiting, flatulence, diarrhea, ear problems, coughing, sneezing, and wheezing. It is worth noting that most true allergies seen in pets with skin disorders are due to fleas, dust mites, grasses, pollen, and other environmental issues. If the immune system is truly compromised, flea insensitivity and dermatitis can be triggered.  

Food intolerance symptoms are usually less serious and are mostly associated with digestive problems.

How to Tell if Your Cat Truly Has a Food Allergy

Veterinary practices will be able to offer allergy testing in order to try and identify the potential causes for the symptoms they present with. For food allergies, the vet will suggest a food trial where your cat is given a special food not containing any proteins that your cat has previously been exposed to. This can last up to 2 months. For more information on this contact your local vet.

It is essential to introduce any new food gradually (usually 2-3 weeks) as it takes time for your cat’s digestive system to fully adjust. If you change the food too quickly it could cause an adverse reaction. Do not expect to see any reductions in symptoms immediately as the change will be gradual. 

If you are unsure about what food is best to feed your cat, always contact your vet for advice. See the PSDA website for more advice on food allergies in cats.
