Best Hypoallergenic Cat Food Reviews – Selected for 2020

Cat food allergy, where your cat reacts to a particular ingredient, is a pretty common thing in cats of all ages and breeds.

In fact, studies have ranked food allergy as the third most common type of allergy in felines after flea bites and inhaled substances. (Source)

That said, the top cat food brands are now manufacturing food formulas which help tame your kitty’s tummy troubles while meeting their dietary needs.

These foods are known as hypoallergenic foods.

We searched the market for the best hypoallergenic cat food that you can start giving your allergy-prone cat.

Luckily, we found up to 10 highly effective foods which we’ll share with you shortly.

How can you tell if your cat has a food allergy?

The most visible sign of food allergy in cats revolves around skin irritation. If you notice your pet scratching abnormally, especially around the neck, head, face, and ears, there’s a good chance he/she has a food allergy. Repeated scratching causes redness and swelling on your cat’s skin and even fur loss.

Another way you can tell if your kitty has a food allergy is checking for digestive issues. Has your cat fallen sick frequently of late? Is she having diarrhea and vomiting? Excessive gas sounds? Passing of gas? Frequent bowel movements?

All these can further point to the possibility of a food allergy in your cat.

Check your cat’s feeding habits too.

If your cat is suffering from the digestive issues caused by allergy, they may end up avoiding their food and water, resulting in weight loss. You might want to monitor their weight regularly if you suspect they’re suffering from food allergy.

NOTE: You cat can show allergic reactions to foods they’ve been taking for months or even years depending on how fast or slow their allergic response to that particular food is.

Once you’ve discovered these symptoms in your cat, we suggest that you change their diet ASAP!

Below, we parade our selection of the best cat food for allergies you can start feeding your cat today when you discover the above symptoms…

Things To Look For Before Buying

With sooo many hypoallergenic foods for cat on the market, deciding on which one to buy for your allergic kitty might not be a walk on the park.

Here, we’ll discuss some crucial guidelines to help you make a perfect choice:

1. What’s the food’s source of protein?

The most common types of proteins found in most foods include beef, lamb, pork, turkey, chicken, and eggs.

Most kitties show an allergic reaction to at least one type of these proteins, which explains why you should always look at the main source of protein in the hypoallergenic food you want to buy.

If your cat is sensitive to beef, for instance, you’d want to make sure the food’s list of ingredients has nothing to do with beef.

If your cat has a sensitivity to seafood, you should ensure you buy foods with no fish or fish oils, even if the oils are supplying omega 3.

What if your cat has a sensitive stomach and not an allergy to a specific protein?

In this case, you should go with food which uses soy or whitefish as the primary protein source.

2. Is the formula hydrolyzed?

Hydrolyzation is the process in which the proteins are broken down into small, low weight peptides.

When your cat consumes them in hydrolyzed form, their immune system will not recognize that they’re proteins and will, therefore, not react to them.

Manufacturers usually indicate these types of food as “Hydrolyzed Protein, HP” or “low molecular protein.”

If your cat is suffering from a sensitive digestive tract or stomach, we suggest that you get this type of food for them.

Keep in mind, however, that the hydrolyzation process might make these foods a bit costly.

3. Look for a limited ingredient cat food

Limited ingredient cats are also suitable for cats with food allergy.

Just a quick reminder…a limited ingredient diet is where the food is made using fewer ingredients to help reduce the possibility of your taking in an allergen and triggering a reaction.

Again, this type of food is based on the fact that proteins—especially beef, fish, and dairy products—are the main causes of allergy in cats.

With this info at hand, the manufactures usually use a single source of protein (usually chicken or duck).

Since carbohydrates can also trigger an allergy, manufacturers usually prefer sweet potatoes or peas for this kind of diet as they provide your cats with lots of energy and are highly digestible.

4. Wet vs dry cat food: Which one to choose?

As you have seen in our list of top hypoallergenic cat foods, they can come in wet or dry form.

Here, we suggest that you stick to the type of food that your cat is used to for. For instance, if your cat takes dry food, stick to dry food and vice versa.

However, you might consider getting your kitty wet canned food if she’s experiencing chronic diarrhea or vomiting to help keep her hydrated.

Overall, whether to choose dry or wet food should strictly depend on your cat’s specific preferences.

More tips:

  • Foods to avoid: as much as possible, avoid all foods which contain ingredients associated with allergies and intolerances in cats. These include grains, dairy, eggs, meat byproducts seafood, artificial colors and preservatives
  • Good cat food for allergies should also be a complete, balanced diet. It should provide your cat with additional nutrients, e.g., antioxidants, fatty acids, amino, etc., to help improve their body health, both internally and extramurally.

Frequently Asked Questions

1. What food is good for cats with allergies?

If your cat is showing negative reaction, you should consider feeding him with hypoallergenic foods—special formulations which try to eliminate the possible allergens in your cat’s diet.

A good example of these formulas is the hydrolyzed which involves breaking down the proteins into small particles so that your cat kitty’s immune system can’t recognize them as the allergy triggers.

You might also consider the dietary elimination trials—where you feed your cat with limited ingredient diets which usually contain fewer ingredients. This will help significantly minimize the possibility of your cat taking in specific ingredients which might be triggering allergic reactions in your cat.

2. What causes food allergies in cats?

The allergies in cats are usually attributed to protein sources (i.e., the meat in your cat’s food).

In general, here are the key causes of food allergy in cats:

  • Food: the presence of ingredients such as beef, dairy, eggs, fish, etc., in cat foods has been shown to cause allergy in most cats.
  • Medications: certain cat medications might end up damaging your cat’s digestive system, resulting in food allergy or intolerance. Surgery, inflammation, and infection can also cause food allergy.
  • Breed: though food allergy can occur in any cat breeds, some breeds are more prone to this problem. A good example is the Siamese cats.

Keep in mind that cat food allergy can take months or even years before showing in your kitty.

Your cat can also abruptly develop allergy or food intolerance for food you have been feeding with her for a long time.

3. Food allergy vs food intolerance: do they mean the same thing?

No, the two terms mean different things. A food allergy refers to the adverse reactions to various foods and involves the cat’s immune system while food intolerance describes the adverse reaction to food which doesn’t involve the immune system.

Your cat can experience the same food allergy while food intolerance might get triggered specific ingredients or even environmental conditions.

Understanding the difference between the two food-related issues is essential in helping you differentiate their symptoms and use the best treatment approach.

4. How long does it take for cat food allergy to go away?

As long as you take action fast—by switching your cat’s diet to hydrolyzed diet or simply the hypoallergenic formulas—your cat should be able to show improvements in 6-8 weeks.

If the symptoms don’t go away after a long period of feeding your cat with cat food for allergy, reach out to your vet for professional advice.

Final Verdict

Food allergy is pretty normal among cats of various all ages and breeds. It’s usually triggered when your kitty body negatively reacts to a particular ingredient in the food you give to them.

The most common symptoms of food allergy in cats include excessive skin scratching around the neck, head, ears, and even the face.

Vomiting and diarrhea are also associated with food allergy.

If you observe any food allergy symptoms in your cat, we advise you to change their diet to hypoallergenic foods—the unique formulas designed to eliminate the ingredients usually associated with cat food allergy.
