Although we often think of allergies as problems that only affect people, it’s also possible for animals to develop allergies. Your cat might become allergic to pollen, fleas or even certain foods.

Allergies in cats can develop suddenly, without any warning. If a cat has a food allergy, it’s very likely that you’ll need to change his diet. Finding out what your pet is allergic to is the first step. The next is choosing the best hypoallergenic cat food to keep him from experiencing additional reactions.

Cats and Allergies

First, the good news about cats and food allergies. Allergies to food aren’t as common as many people think they are, according to the Veterinary Medical Center at Tufts.

That said, food allergies are the third most common type of allergy in cats, according to the Cornell Feline Health Center. All told, food allergies make up about 10 percent of allergy cases in cats. The other two more common types of allergies include flea allergies and allergies to inhaled substances (such as pollen).

For a cat to develop an allergy to a particular food, he would need to be exposed to that food. A cat who’s never eaten wheat can’t be “allergic” to wheat since his immune system would never have the opportunity to develop an antibody or immune response to the grain.

For that reason, there’s a certain unfairness that comes along with food allergies. A cat who has enjoyed chicken or fish for many years might one day become allergic to either the chicken or fish, making it difficult, if not impossible, for the cat to eat either of those foods.

What Are Cats Allergic To?

It might surprise you that foods cats are most likely to be allergic to are also the foods that are most commonly found in a cat’s diet. Among the most common allergens for cats are:

  • Chicken
  • Beef
  • Dairy
  • Eggs
  • Fish

Many people make the mistake of assuming that foods such as wheat and other grains are the most likely to cause allergy issues for cats. But, as Tufts points out, it’s much more likely for a cat to develop an allergy to an animal protein than for a cat to develop an allergy to grain.

Of course, some cats do end up with grain allergies, which is why it’s so vital for you and your cat’s vet to figure out the cause of the allergy before choosing the best hypoallergenic cat food for your pet.

Signs of Food Allergies in Cats

One of the more interesting things about food allergies in cats is that they don’t cause the type of symptoms you might typically associate with a food allergy.

For example, when a person has a food allergy and comes into contact with the allergen, they are likely to break out into hives or, in extreme cases, go into shock.

In cats, the most common type of reaction to a food allergen is itchy skin. If your cat is allergic to something he ate, he’s likely to develop a series of small bumps on the surface of his skin, according to Cornell.

The most common location for the itching and the bumps is on the head or near the neck. It’s also possible for cats to have itchiness elsewhere on their skin.

The bumps themselves usually aren’t much of a problem. If your cat were able to leave them alone, food allergies wouldn’t be a big deal.

But, it’s a rare cat who’s not going to scratch when he has an itch. It’s the scratching that can make the allergic reaction a problem. Depending on how much your cat scratches in an area, he might develop an infection or cause enough damage to the skin for a wound to form.

Often, it takes some time to notice that a cat is having an allergic to reaction to a food. You might just assume that your cat is itchy when you first see him scratching.

But repeated scratching over the course of weeks and months can have some adverse effects on your cat’s appearance and health.

Cats who scratch too much might develop areas of hair loss, leaving bald patches behind. The overall quality of your cat’s fur or coat might deteriorate as well. Depending on how much he scratches, you might notice visible skin lesions or wounds as well.

While skin problems are the most common symptoms of food allergies in cats, some also develop gastrointestinal issues. According to Cornell, up to 15 percent of cats with food allergies have vomiting, diarrhea, or other signs of gastrointestinal distress.

Diagnosing a Food Allergy

Figuring out whether your cat has a food allergy or if something else is to blame for his problems is both challenging and manageable. Since so many other things, such as flea bites, other insect bites, parasites, bacterial infections and other illnesses, can cause itchiness or gastrointestinal problems, it can take cat parents a while to figure out that food might be the culprit.

Once you’ve determined that it might be food that’s causing your cat’s discomfort, the next step is to bring him to the vet for a checkup. Your vet might perform a skin allergy test to identify the allergen.

It’s also very likely that your vet will ask you to put your cat on a “novel” diet. Essentially, that means you’ll change everything about what your cat eats. The more common “cat foods” such as chicken, fish or beef are eliminated from the diet, and you’ll give your cat foods such as duck, venison, or rabbit (unless he already eats those).

It’s also likely that the novel diet will be grain-free, as there is a small chance that your pet is allergic to certain grains.

Typically, the novel diet will include just a single source of protein, one that your cat has never eaten before. It might also include a source of carbohydrates, such as sweet potatoes. The important thing is that the food in the diet before foods your cat has never been exposed to before.

Usually, your cat will be on the special diet for 12 weeks, according to WebMD. After that period, you can start gradually reintroducing foods into his diet. For example, you can try feeding him chicken again to see if the chicken is what triggers the symptoms.

Allergies vs. Intolerances

It’s important to understand that there’s a difference between a true food allergy in your cat and intolerance to certain foods. Intolerance to food usually stems from an issue in the digestive system, not the immune system.

For example, if you feed your cat a diet that primarily consists of the cheapest cat food available and that cat food is full of additives, his digestive system might not be able to tolerate the food. Intolerance to food additives can cause diarrhea, vomiting, and other digestive troubles.

An intolerance often stems from the way the food is prepared, not from the food itself.

Reviews of the Best Hypoallergenic Cat Food

While you want to work with your cat’s vet during the initial stages of diagnosing an allergy and only feed him what the vet recommends at that point, once you’ve figured out the source of the allergy, feeding your cat the best hypoallergenic cat food can help him avoid further reactions.

The best hypoallergenic cat food depends on what your cat is allergic to and what he can tolerate. We’ve reviewed some of the best options available and have noted what makes them a good choice and what might make them not such a good choice for some cats.
