Best Cat Food for Cats with Allergies

Did you know that your cat may have allergies to certain cat foods?

Sometimes a cat’s immune system mistakes an ingredient for a threat and responds in a way that can result in many unpleasant symptoms and leave him feeling quite out of sorts.

Cats most commonly develop these food allergies between the ages of 2 and 6 years old and must be consistently exposed to the allergen to develop signs of a problem.

They can sometimes develop food allergies to protein sources such as fish and chicken, for example. Signs of a problem can include symptoms such as vomiting, diarrhea, flatulence, itchy skin, loss of appetite, hair loss or reddened skin.

It’s easy to mistake these symptoms for something else, so if you find that you are unsure about what may be causing the problem, it is always best to seek advice from your veterinarian. 

If you or your vet suspect a food allergy, it may be a good idea to try a hypoallergenic cat food. Switching to hypoallergenic cat food can help to avoid symptoms by actively eliminating particular ingredients your cat may be sensitive to from his diet.

We’ve researched everything there is to know about the best hypoallergenic cat food that will leave your kitty feeling better in no time! Read on to find out about our top five picks for the best hypoallergenic cat food and what to look out for in our handy buyer’s guide.

Our first choice, the Natural Balance Limited Ingredient cat food, is a great option for your cat as the limited ingredient content reduces the possibility of your cat being exposed to potentially harmful allergens.

Green peas are a high-quality carbohydrate and are very easy to digest in this form, providing your cat with much-needed energy and nutrients. This grain-free cat food helps support healthy digestion and does not contain any artificial flavors or colors which may upset your cat.

It is also free of potatoes, corn, wheat and soy, which can sometimes be addictive to cats.

This 2-pound bag of food should last you quite a while and offers excellent value for money. Natural Balance cat food helps to support healthy skin and should leave your cat’s coat soft and shiny thanks to the combination of balanced Omega-6 and Omega-3 fatty acids and high-quality protein.

The grain-free Blue Buffalo wet food features a single animal protein source to help support the energy needs of adult cats. The food is free of chicken, beef, corn, wheat, soy, dairy and eggs, so if you know that your cat has an allergy to one of these ingredients this is the perfect choice for you.

You also won’t find any artificial colors or preservatives here. The food itself has a smooth texture akin to a paté style which should please your cat and be easy for them to digest. The Blue Buffalo cat food is a little more expensive than other types of hypoallergenic cat food, but this one comes in a 3oz pack of 24 tins, so it should last you a while.

The Omega content should help to promote skin and coat health for cats with food sensitivities. The added fish oil should also help to address dry or flaky coats and leave your cat looking shiny and sumptuous.

The Naked Essentials canned wet food from the ‘I and love and you’ store is the perfect choice for cats with food allergies.

There are several tasty flavors to choose from which promise to be gentle on your cat’s sensitive stomach, we especially like the ‘Oh My Cod! Pate’ flavor. The brand is a fairly new contender on the cat food market but is already an increasingly popular choice for cat-lovers.

The cod flavor is an all-natural, no-filler, grain-free cat food that features cod as its primary ingredient. Cod would be an ideal source of protein to offer your cat if they have shown allergies to other meats.

Instead of grains, the Naked Essentials food is packed with nutrient-rich cranberries and spinach, which will allow you to maintain a healthy balanced diet for your cat.

The omega content and salmon oil help to improve the health of the skin and coat to promote a soft and shiny texture. If you’re after a gentle formula that will be gentle on the stomach and suitable for cats with food allergies, this one is a winner.

This hypoallergenic cat food is made with whole whitefish, salmon, grains and vegetables. Halo’s dry cat food is designed to provide more bioavailable nutrients to aid digestion and be gentle on the stomach.

Many types of cat food are filled with starchy fillers such as corn and potatoes, which are used to reduce the amount of meat and protein. It is exactly these kinds of fillers that can cause problems for your cat as they are often the most common allergens.

This is where Halo cat food comes in. The Halo holistic seafood range contains whole fish only which is considerably easier to digest than a comparable cat food which features by-products or fillers.

All the fruit and vegetables that feature in the Halo sensitive food range are sourced from farmland that actively prohibits the use of genetically modified seeds, and the wild seafood is sourced from sustainable fisheries that raise animals naturally.

This is a brand that has an environmental conscience, and you can rest assured that your cat will be able to enjoy healthy, nutritious and natural food with this one. Keep in mind that this cat food is made with grains, however, as this ingredient is not always suitable for all cats. 


  • Made with whole whitefish, salmon, grains 

  • Aids digestion by providing bioavailable nutrients 

  • Does not contain any by-products or fillers

  • Fruit and vegetables are sourced from farmland that prohibits the use of genetically modified seeds 

  • Wild seafood is sourced from sustainable fisheries 

  • Healthy, nutritious and natural 


  • Contains grains which may not be suitable for all cats 


Our final choice for cats with allergies is the brilliant Instinct Original Grain-Free cat food, which is another top-rated choice for felines. If your cat prefers a wet-food diet, the Instinct Original cat food is sure to please him.

Made with wild-caught salmon, this cat food is very high protein and doesn’t contain any traces of potato, soy, corn, wheat, carrageenan or artificial colors or preservatives. You can relax in the knowledge that this cat food doesn’t contain any ingredients known to trigger food sensitives.

It is made from real meat and whole food ingredients and is designed to provide the protein needed for strong, lean muscles. The salmon flavor is made with 95% salmon and pork liver and 5% fruits and vegetables, which is a very good ratio considering other cat foods often contain a lower percentage of protein.

Suitable for cats of all ages, the Instinct Original cat food is a high-quality option that can be served as a meal or topper and has a smooth, paté texture that even the pickiest of cats is sure to enjoy.

This would be a good choice for elderly cats who may struggle with digestion problems or adult cats with corn or wheat sensitivities. This is a slightly more expensive option, however, but we feel that the gentle, natural formula justifies the extra expense.

Best Cat Food for Cats with Allergies Buying Guide

Wet or Dry Cat Food 

Many older cats experience food allergies or intolerances. For these cats, it can be best to opt for wet food as they may struggle to chew hard kibble or find it hard to swallow dry food due to teeth problems or failing health.

In addition to this, if you give your cat only dry food he may get dehydrated (since wet food can help to increase water intake). Ultimately, it comes down to your own personal preferences, but many owners find that a balanced diet of both wet and dry food works well for cats. 

Protein Source 

It’s important to think about the protein source in your chosen cat food as some cats can be allergic to beef, eggs or fish.

If you think your cat may have an allergy to one of these protein sources, it may be a good idea to try an alternative such as chicken, turkey or duck as these often fare well for cats with allergies.

Try to pick a cat food that features meat as the main ingredient and ideally has only one or two protein sources for easy digestion.  

Ingredients to avoid 

There are a couple of ingredients to avoid if your cat is prone to food allergies.

It’s a good idea to look out the following ingredients as they may even feature in ‘limited ingredient’ cat foods, and include grains, meat by-products, dairy, artificial colors and preservatives and some types of seafood.
