Overall Best Cat Food For Allergies

CRAVE Grain Free High Protein Dry Cat Food

Crave’s grain free cat food is our overall favorite cat food for allergies. It doesn’t have grain, corn, soy, or by-product and tries to mimic the natural diet of a cat. It’s a good overall pick.

This formula is a good overall pick for cats with allergies because the cat food is designed to mimic the natural diet that cats consume. The cat food contains real chicken or salmon, depending upon the flavor you get for your cat.

The dry food keeps your cat full and satisfied for longer because it is packing in the protein. Crave is a high 40% protein so this is a good pick for overweight cats who need to shed the pounds and very active cats.

Since it is made for cats with food sensitivities, the formula has immune system strengthening properties.

Our only nitpick here is that the price per pound is a little high, but it’s not too bad compared to some of the other options.

The all-natural ingredients mean that your cat gets only the most wholesome and energetic foods they need without containing any processed additives that are responsible for allergic reactions. Made to mimic cats’ ancestral diet, the CRAVE formula ensures your cat’s healthy development.

Things We Like

  • Good pick if your cat has grain, by-product, corn, wheat, or soy allergies
  • Strengthens the immune system
  • Very high protein

Things We Don’t Like

  • Price per pound is a little high, but it’s not too bad

Best Cat Food For Extreme Allergies

Royal Canin Veterinary Diet 

The Royal Canin Veterinary Diet is our favorite cat food for extreme allergies. It sells at a premium, but there’s no other food with a better chance of getting rid of your cat’s allergies.

We recommend this food if nothing else has worked.

Royal Canin Veterinary Diet is perfect for cats with allergies. This hypoallergenic cat food is specifically made for cats with allergy issues. Rabbit and peas are the main ingredients, both of which are suitable for cats that are normally allergic to most things. The cat food is rich in protein so your cat can stay active all day long. The high protein content also assures that your cat gains lean muscle mass and strength, so this is a good pick for overweight cats or very active cats.

Despite being designed for cats with food sensitivities, the Royal Canin is a complete meal, supplying your pet with all the necessary nutrients. The cat food includes EPA, DHA, and omega-3 fatty acids, ensuring that limited ingredients do not mean limited nutrients. Omega-3, in particular, is great for your cat’s skin and fur. The formula also boasts B vitamins and amino acids that strengthen the natural defense mechanism of the skin.

So it’s good for overall health and does a great job at allergy relief, but it’s pretty pricey.

Things We Like

  • Great for cats with extreme or pervasive allergies

  • Helps skin and fur health

Things We Don’t Like

Another thing that makes it perfect for cats with allergies is that it’s free of any artificial flavors or colors. Lots of protein gives provides energy throughout the day, so another win for overweight or overactive kitties.

This food has weird pricing on Amazon: per pound the 5-pound bag is less expensive than the 11-pound bag. If you want 11 pounds, we recommend buying 2 5-pound bags 🙂 The pricing for the 5-pound is very reasonable (about $2.50 per pound). The pricing for the 11-pound is less reasonable (almost $4 per pound).

Weird, but no problem.

The Simply Perfection cat food has salmon as the main ingredient. So if your cat loves salmon, this one is a winner.

Lots of protein helps build strong muscles and makes your cat feel more full after eating.

Simply Perfection passes on grains, corn, wheat, and soy. This formula is also completely free of any artificial colors or flavors. Overall it is a natural formula which is easy to digest and does not contain any of the most common ingredients that may cause an allergic reaction in cats.

Additional ingredients include broccoli, spinach, and carrots, meaning your cat gets a wholesome meal with added vitamins and minerals. As with most wet foods, this is a little pricier than a dry food per meal. So say a dry food costs $0.25 per meal, this food costs about $0.50 per meal.

  • No grain, corn, or soy. Good pick for cats who have those allergies

Best Budget Cat Food For Allergies

Purina Beyond Grain Free

Purina Beyond is our favorite option for budget shoppers. It’s dry, so a little bit less expensive than wet varieties and it sells at a great cost per pound.

This cat food formula promises high quality nutrition for your cat. Formulated by veterinarians, the food is designed to be easy to digest and full of nutrients. This food is pretty high in proteins, so it’s a good pick for active or overweight cats. It’s not the highest in protein, but it’s much higher than most budget cat foods.

One thing I like about this food is that it comes in several flavors. My cat tends to dislike less expensive foods (to my wallet’s detriment, she’s a cat of refined tastes) so I like that there are several flavors here to choose from.

Several buyers commented that this food helped their cats have less stomach problems. This might be a good cat food for vomiting. I know that it is a great pick for an allergen free cat food; no soy, corn, or wheat here.

The kibbles in this food are a bit big, so it’s not a good pick for cats who have teeth problems.

What We Like

  • Great budget pick
  • No grain, corn, or soy
  • Might help with stomach problems
  • Lots of flavor options

What We Don’t Like

  • Big kibbles make this a bad pick for cats with teeth problems

This is our favorite budget pick. It skips out on a lot of potential allergens for kitties and still sells at a super reasonable price.

Things to know before you buy

Food-related allergies are the third most common cause of allergies in cats, just behind fleas and inhaled substances. An allergy is defined as an immune system response. In the case of food-related allergies, this immune system reaction is triggered by an ingredient in the food. At times these allergies are the result of a combination of an intolerant ingredient coupled with a metabolic problem, like the deficiency of an important digestive enzyme.

Food allergies can be quite debilitating and can bring about quite painful symptoms in cats. So much so that they may need getting checked up by a vet right away. Some common symptoms of allergies:


Allergens can cause severe itching in cats.  The itching is a result of little, pale fluid-filled lumps that appear once a food allergy kick in. It is usually the head and neck area that become the most irritated. Constant scratching to relieve themselves of the itching can result in hair loss, coat deterioration, and eventually wounds on the skin. Itching is especially uncomfortable and may be mistaken for fleas, so going to a vet is a good idea.

Redness and inflammation:

Sometimes cats get redness and inflamed skin instead. This condition is equally uncomfortable and can be a source of great distress to your cat. Usually itching and inflammation occurs together and can damage your cat’s skin due to continuous scratching which cats do as a way to get some relief.

Stunted development:

Not applicable for adult cats, but a food allergy can have the effect of stunting your kitten’s growth and development. Food allergies can negatively impact the normal growth in cats, which can be a real problem.

Gastric problems:

Food allergies can magnify a pre-existing condition, such as gastric problems like the deficiency of an important enzyme. In such situations, the most common symptoms can be gastro related. An upset stomach, flatulence, and stomach ache occur. The problem is a lot of the times you might think it is a stomach related issue, while the real problem may be a food allergy that triggered the gastro problems in the first place.

Coughing and sneezing:

Just like in humans, cats may actually be developing coughing, sneezing, and whizzing as symptoms due to a food allergy. Again, these may be confused with the symptoms for the common cold, so it is always better to double-check with your vet first. The prescription should be based on clinical diagnosis; after all, otherwise, the treatment will be no good.

Vomiting and diarrhea:

Some cats may experience vomiting and diarrhea in reaction to consuming an ingredient they are allergic to. This happens as the body rejects the ingredient causing the allergic reaction and tries to get it out of the system completely. Vomiting and diarrhea can result in dehydration, so a visit to the vet is important as soon as you notice that your cat starts to develop any of these symptoms.

If you aren’t sure why your cat is vomiting, check out our guide on why cats throw up.

Common food items causing allergies:

The most common sources of food allergies have to be artificial ingredients used in some foods, like artificial colors, artificial flavors, preservatives, and so on. These man-made chemicals may not be tolerated by your cat and may result in an allergic reaction.

Certain types of proteins may also cause an adverse reaction. There is no specific protein; it varies from cat to cat. So your cat may be allergic to animal-based proteins, like those found in tuna or chicken or beef.

Carbohydrates like soy, wheat, rice, and potatoes are also potential allergens. Carbs are generally discouraged anyway because they can cause cats to become overweight, which is never a good thing.

Cats are also very sensitive to dairy products. So avoiding milk, cheese, and other dairy-based products is a must if your cats start developing symptoms of food allergies.

How are food allergies diagnosed?

Some symptoms of food allergies resemble stomach related problems or even symptoms usually associated with the common cold. This is why you should always consult your vet first.

To diagnose allergies, the vet will run blood work on your cat and change up the diet. Putting your cat on a restrictive diet can help isolate the ingredient causing the problem and help discover a potential allergen.

Sometimes cats can develop an allergy to an ingredient due to age as well. This means they can become intolerant to an ingredient they had no trouble consuming previously.

Preventive measures:

While curing an allergy always requires medical intervention, you can avoid the hassle by taking preventive measures. Putting your cat on a restrictive diet may sound wrong, but it is actually an excellent idea. Limiting the amount of ingredients consumed can help you in a number of ways. It prevents your cat from putting on weight, especially if you feed your cat grain-free food. And it also reduces the chances of your cat developing an allergic reaction.

So careful selection and maintenance of a diet are crucial if you wish to save your cat from developing an allergic reaction.


Food allergies are cured through food. Your vet may give medication to relieve your cat of the painful symptoms, but the actual treatment involves the removal of the offending ingredient from your cat’s diet completely. Once they come down with an allergic reaction, they will not be able to consume that articular ingredient without having an adverse reaction to it.
