According to Cornell University College of Veterinary Medicine, research shows that overall food allergies are the third most common kind of allergy in cats.
Food allergies in cats are outranked only by allergies to flea bites and allergies to inhaled substances. A cat can develop food allergies at any age, and a cat can become allergic to ingredients in her diet she’s been eating for years.
What Are Food Allergies in Cats?
According to Cummings Veterinary Medical Center at Tufts University, a food allergy occurs when a cat’s immune system identifies an ingredient in the cat’s diet as an invader rather than a food substance. The cat’s body mounts an immune response, resulting in allergic symptoms.
Symptoms of Food Allergies in Cats
Your cat may develop small, pale, fluid-filled lumps or lesions on his skin in response to a food allergy. These lesions typically cause your cat to scratch its skin. The itchy lesions commonly affect the cat’s head and neck, but they can also affect other parts of your cat’s body.
Though the itchy lesions do not pose a significant health problem in and of themselves, the constant scratching your cat does in response to them may lead to secondary skin wounds and bacterial infections.
According to Cornell University College of Veterinary Medicine, 10-15% of cats with food allergies also exhibit gastrointestinal symptoms, such as vomiting and diarrhea. Gastrointestinal issues due to food allergies may lead to food avoidance that may result in dangerous weight loss and health problems.
What Are the Most Common Food Allergies in Cats?
Food additives are often blamed for causing allergies in cats. However, this is rarely the case. According to VetInfo, the most common food allergies in cats include to seafood, beef, and dairy.
Cummings Veterinary Medical Center at Tufts University adds that eggs and chicken are also among the most common food allergies in cats.
This YouTube video explains what cat food allergies are as well as how they differ from food sensitivities. It also discusses the most common types of food allergies in cats, how cat food allergies are diagnosed, and how they are treated.
How Are Food Allergies Treated in Cats?
Before your cat can be treated for a food allergy, it is important to determine what he is specifically allergic to. If a food allergy is suspected, your veterinarian will have you change your cat’s diet to one that contains a novel protein and carbohydrate source – ingredients your cat has not previously been exposed to, such as rabbit, duck, green peas, and potato.
Alternatively, your veterinarian will prescribe your cat a hydrolyzed diet where the protein in the food is broken down into such small pieces that it can effectively hide from your cat’s immune system.
While you feed your cat an elimination diet, you must not feed him any other cat food, treats, or people’s food. It is essential that he eats only his elimination diet during this period.
After your cat has eaten his elimination diet for six to 10 weeks, your veterinarian will have you introduce ingredients back into your cat’s diet one at a time until you discover the source of your kitty’s allergy.
When you have determined what ingredient your kitty is allergic to, you will need to avoid feeding your cat that ingredient in his diet for the rest of his life to prevent future allergic reactions.
How Do I Change My Cat’s Diet?
When it is suspected that your kitty has a food allergy, a rapid diet change is in order. When you need to make a rapid diet change, PetMD suggests initially offering your kitty a small meal of the new food.
If she does not have any stomach issues, offer her another small meal of the new food in a few hours. Continue to offer meals in increasing sizes over longer periods of time until you have reached your cat’s normal feeding schedule again.
If your cat initially refuses to eat her meal, pick the food up, and do not offer her anything else. It is okay to let your kitty get a little hungry.
Try to offer her the new food again in six to eight hours. If she refuses to eat it again, pick it up, and offer it to her in another six to eight hours. Continue this process for 24 hours.
If your kitty refuses to eat the food within 24 hours, consult your veterinarian for another formula of food to try with your cat. You should also consult your vet if your cat has stomach problems after eating her new food.
How to Choose an Appropriate Diet for a Cat with Food Allergies
It is best to consult with your veterinarian about the food you feed your cat. Cats are obligate carnivores, which means they must eat meat in order to survive. You want to make sure that the first ingredient in your cat’s food is meat. You will also want to make sure the food you choose to feed your cat has taurine in it.
Taurine is an essential amino acid your cat cannot make and, therefore, he must get from his diet. Though cats do not need carbohydrates, most pet food companies use them as fillers.
Limited ingredient diets are good for kitties with food allergies because they typically only have a few ingredients and contain all the vitamins, minerals, and nutrients your cat needs.
Ensure whatever food you decide to feed your kitty meets the American Association of Feed Control Officials (AAFCO’s) requirements for, “Complete and Balanced.” Foods that meet this requirement will say so on the label.

Spruce Pets suggests avoiding certain ingredients in your cat’s food. They suggest avoiding by-products, meat and bone meal, animal digest, and added sugars.
They also recommend avoiding chemical preservatives, such as BHT, BHA, propyl gallate, and ethoxyquin. Cornmeal should be avoided as a filler.
If you suspect your cat has food allergies, take him to your veterinarian. Your vet will help you determine if food allergies are a likely cause of your cat’s symptoms.
If food allergies are likely, your vet will help you get your cat on an elimination diet and help you determine what, if anything, your kitty is allergic to.
Once you have a confirmed diagnosis of food allergies for your cat, you will need to avoid feeding him whatever he is allergic to in his diet.
Limited ingredient diets are good for cats with food allergies because they expose kitties to fewer ingredients that could cause issues.
Consult your veterinarian about trying one of the limited ingredient diets for cats discussed in this article as a way to treat your cat’s allergies.
