Things to Look for in Hypoallergenic Cat Food
There are many foods that claim to be hypoallergenic or that claim that they can be used in a limited-ingredient diet. Some are suitable for use as part of an elimination diet and will help you to work out what your cat is allergic to. Others are suitable for cats that have a diagnosed food allergy.
It is important that you get advice from your vet about which food will suit your cat best based on their particular allergy, their breed and their age. Some diets are only suitable for indoor cats and others suit cats that go outdoors.
Here are some of the things that you may want to look out for in the best cat food for cats with allergies.
- Hypoallergenic – hydrolyzed protein
Proteins are the main substance that triggers an allergic reaction but cats need protein in their diet so you cannot eliminate it altogether. However, in truly hypoallergenic cat food brands, the proteins have been broken down into such tiny pieces that the cat’s immune system doesn’t realize that they are proteins and doesn’t react! You will see this written on the package as ‘hydrolyzed’ protein or as protein that has a ‘low molecular weight’.
The idea behind hydrolyzed protein cat food is that the allergen has been completely removed so your cat will feel better. It is then up to you to work with your vet to introduce other foods one at a time to work out what they were allergic to.
- Limited ingredients cat foods
Other cat foods are described as ‘limited ingredient’. This means that the protein and carbohydrate content are provided by one or two foods. Protein-rich foods are a common culprit in food allergies and studies have shown that beef, dairy products and fish are very common triggers. Therefore, this type of diet often uses one source of protein which is often chicken or duck.
The source of carbohydrate is also limited because some carbohydrates can trigger allergies. Commonly, sweet potato and peas are chosen as they provide plenty of energy and are easy to digest.
- Free from…
When it comes to cats with allergies, you should be as interested in what the food does NOT contain as in what it does contain. Grains can be a particular issue and are not necessary in a cat’s diet. The gluten content of wheat and corn can trigger allergic reactions so look out for ‘no corn, wheat or soy’ on the label of the best cat food for food allergies.
Foods that are free from artificial additives are also best as these are not necessary and can cause problems. Finally, any form of meat by-product meal is best avoided as you cannot be sure what is in it.
- Balanced nutrition
The best cat food for allergies also offers balanced nutrition for your cat. Some added micro-nutrients can be very useful. Any vitamin that boosts the immune system will help.
The best cat food for skin allergies also contains omega oils which help to soothe inflamed skin and stop cats from scratching so much. Natural fiber can also help a damaged digestive system to recover. Find out more about high fiber cat food here.
Ingredients To Avoid Feeding Your Hypoallergenic Cat
Cat food allergies can be triggered by many different ingredients. Your vet can help you to work out what is causing the problem. Here are some of the most common culprits.
- Lamb, Beef and Seafood
These are very common ingredients in cat food as they provide the protein content. It is possible for you to avoid them by choosing a food that uses a single source of animal protein that is something like deboned chicken or duck. Cat food made with hydrolyzed soy protein contains no meat protein at all and is therefore also suitable for cats with this allergy.
- Meat by-products
These are the parts of an animal carcass that humans do not want to eat so it includes things like skin and hoof. They are cheaper than muscle meat and therefore attractive to some pet food manufacturers. However, they are not as nutritionally valuable and can trigger allergies.
- Corn grains
This is another cheap ingredient that can cause problems. It is commonly used as a filler because it bulks out the food and is cheap but many cats are allergic to cornmeal, corn gluten meal or to all forms of corn. Typically, the allergic reaction will be itchy and dry skin.
Some experts also suspect that fillers such as corn can trigger diabetes in cats.
- Wheat grains
Wheat is another cheap carbohydrate that is used as a filler in pet foods but wheat gluten is a common allergen. Many cat foods are now gluten free so it is quite easy to avoid if you read the labels carefully. For a wider selection of choices, check out our grain free cat food guide.
Eggs are a high protein food that are an alternative to meat protein. They are a popular ingredient in some wet cat food. However, some cats are allergic to them.
- Soy products
This is a plant-based protein that would not form part of a wild cat’s natural diet because they prefer meat! Some cats are allergic to it so many foods are now free from soy. However, for cats that are allergic to meat proteins, foods based on hydrolyzed soy protein are a safe alternative.
- Artificial additives
Artificial colors, flavors and preservatives are added to some cat foods and they can trigger allergic reactions. There is no need for color to be added at all because cats do not care about the color of their food! Natural flavors and preservatives are always preferable.
Symptoms of a Food Allergy in Cats
Cat food allergies can present themselves in many different ways. Many of the symptoms of an allergic reaction can be caused by other things. Therefore, you should never try to make the diagnosis yourself and should always consult your vet.
Here are some of the common symptoms that you may notice.
- Respiratory problems
This could be sneezing, coughing or wheezing. Your cat may snore loudly because they have an inflamed throat.

Q: What are food allergies in cats?
A cat’s immune system is designed to protect them from invaders such as bacteria and viruses. When these pathogens enter the body, it reacts to protect itself. Sometimes, the body also reacts to substances (usually proteins) that are not harmful and this is an allergy. The reaction can be anything from sneezing to a skin rash. The substance that causes the allergy is caused an allergen.
There are many potential allergens in cat food and the allergy can develop at any age. Your cat can eat a food for years and then become allergic to it.
Don’t forget that cats can be allergic to lots of other things besides food. Some cats are allergic to flea bites, perfumes, scents in cat litter and plastic materials. These could all be to blame for your cat’s symptoms.
Q: How can I determine the allergy of my cat?
You need to work with your vet to determine the exact cause of your cat’s allergy. It is not easy to make a diagnosis because there are no allergy-specific tests that can be used. The symptoms are not specific and could be caused by other things. The allergy triggers can be inconsistent.
Your vet may try some intradermal skin tests but blood allergy tests are not so reliable. They may also recommend an elimination diet.
This involves feeding your cat a special diet that contains only hydrolyzed protein and so it will not trigger an allergic reaction. They eat only this for 12 weeks and cannot even ingest flavored medications or treats at this time. Once the symptoms have resolved, you can start to re-introduce foods one at a time and observe which of them causes an allergic reaction.
Q: How should I treat food allergies in my cat?
The best approach is to prevent exposure to the offending allergen. With food allergies, this means that you have to choose your cat’s diet carefully. Once you have found a food that does not contain the allergen, you need to stick to it. Remember that treats can trigger allergies too.
Also, new allergies can develop over time so be on the lookout for new allergic reactions. You may need to change your cat’s diet again to accommodate these.
You may want to choose a food that has fatty acids or give supplements to help your cat if they have itchy skin. Whilst their skin is inflamed, it is vulnerable to infection and there are shampoos that can help to prevent this. Oatmeal and aloe sprays can also help.
Q: What are the consequences of an allergic reaction to the cats?
Allergic reactions can make your cat’s life a misery. It is no fun having chronic diarrhea or constantly itchy skin.
The on-going allergic reaction can cause other health problems. Skin that is constantly inflamed and itchy is prone to getting infected. Also, you can be mistaken into blaming the allergy for symptoms that are actually caused by another disease. This can be risky and could result in serious diseases being missed.
It is always best to work with your vet to get to the bottom of what is causing the problem.
