The Best Dry Cat Food for Allergies in 2021

In this article, I will be talking about the best dry cat food for allergies. Cats with food allergies need an elimination diet to find out what foods are causing the allergies.

I chose ZIWI Peak Air-Dried Cat Food as the best dry cat food for allergies. This food contains a high amount of quality protein from lamb. This is a limited ingredient novel protein food.

Cats are allergic to many things including dust, fleas, pollen, and food. About 10% of allergies are food-related.

Food allergies develop from progressive exposure to common food proteins. Typical food allergens include common protein sources such as chicken, beef, fish, wheat, and dairy.

Uncommon (novel) protein sources may give your cat relief from allergies. These protein sources include lamb, rabbit, duck, and goat.

An elimination diet restricts the use of common food proteins and uses either novel proteins. The owner then trials their cat with individual food items to identify the problem food. Removal of the food is the only solution after identifying the problem food.

In some cases, vets prescribe a specialty veterinary diet. This involves the use of hydrolyzed food. This food is not intended for regular dietary use.

At Simply Cat Care, we recommend the best quality food to improve your cat’s chance of living out a happy life. In this review, I’ve analyzed the best dry cat food for allergies on the market to find which ones are suitable for your cat.

I am not a veterinarian and I recommend seeking the advice of a vet before making a purchase. Vets diagnose and prescribe the appropriate diet for food allergies.

Let’s get into the review.

Product Review: The Best Dry Cat Food for Allergies in 2021

Best Dry Cat Food for Allergies: Overall

ZIWI Peak Air-Dried Cat Food – All Natural, High Protein, Grain-Free & Limited Ingredient with Superfoods

  • Uses novel proteins lamb and mussels perfect for a hypoallergenic diet
  • Suitable as a limited ingredient cat food using two novel animal protein sources
  • Omega 3 fatty acids from green mussels for your cat’s immune system
  • Grain-free natural food for sensitive stomachs
  • Expensive premium cat food product
  • Limited range of novel protein flavors (only two)


Looking for hypoallergenic cat foods is a tough ask, especially dry cat foods.

The majority of brands have a love affair with peas, potatoes, grains, corn, and tapioca starch. Almost every dry cat food is a ‘nonstarter’ for long-term health.

ZIWI Peak has come to the rescue with its Air-Dried Lamb Cat Food. They use high-quality dried lamb and nutritious New Zealand green mussels. The grain-free food is rich in protein for superb digestion, health, and vitality.

The cost is a little higher than typical dry cat food due to the quality. The only novel protein options are lamb and venison. Some cats may want more variety and flavors.

Best Dry Cat Food for Allergies: Freeze Dried

Stella & Chewy’s Freeze-Dried Raw Dinner Morsels for Cats

  • Uses novel proteins rabbit and turkey which are suitable for a hypoallergenic diet
  • Freeze-dried to retain nutritional value for top health
  • Grain-free natural food for sensitive stomachs
  • Made in the USA from high-quality protein sources
  • Expensive premium cat food product
  • Limited range of novel protein flavors (only two)
  • Lacks the convenience for a dry food


Freeze-dried cat food is another great cat food option.

Unlike dry food, freeze-dried products don’t tend to use carbohydrate-rich peas, potato, corn, wheat, or soy. Cats with sensitive stomachs will appreciate this easy-to-digest product.

Stella & Chewy’s Freeze-Dried contains only the novel protein rabbit (also has a turkey option). Rabbit is one of the better hypoallergenic foods for cat food allergies and nutritious food to add to your cat’s menu.

Freeze-dried cat food is still more expensive than regular kibble for cats. The food also needs preparation with rehydration and heating.

Best Dry Cat Food for Allergies: Canned Alternative

Feline Natural BPA-Free & Gelatin-Free Canned Cat Food, Lamb

  • Uses novel protein lamb suitable as a hypoallergenic food
  • High-quality animal protein for top health
  • Grain-free natural food for sensitive stomachs
  • Trusted New Zealand brand dedicated to the health of your cat
  • Expensive premium cat food product
  • The only novel protein option is lamb
  • Lacks the convenience for a dry food


If you’re wondering why I am offering a canned alternative for a post on the ‘best dry cat food’ it’s because the majority of dry cat food is abysmal. It is a horror show for cats with allergies.

So to guide you in a more sensible direction for your cat consider wet canned cat food. There is a lot better variety of quality in the wet food market.

The Feline Natural is a superb option, using lamb as a novel source of protein. There is no green pea and this is also grain-free for a sensitive stomach. The use of lamb reduces the chance of food allergies in cats, due to its low use in most cat food products. The product uses high-quality meat sources for great skin and coat.

Unfortunately, the only hypoallergenic food option is lamb. There is a beef alternative, which isn’t usually a novel protein but may be worth looking at.

What are cat allergies?

An allergy is something that causes the immune system to overreact. Allergens include hair, pollen, food, dust, and certain medications [1]. Food allergies occur at any stage during a cat’s life.

An allergen can affect the cat via ingestion, inhalation, or contact with the skin. If a cat has an allergy to something then it will have an acute or delayed allergic reaction.

Antibodies are the cause of allergic reactions. They release upon exposure to an allergen. Antibodies release a protein called histamine which inflames areas of the body such as the nose, throat, and digestive system [1].

How do I know if my cat is allergic to food?

If a cat is allergic to something in their food then they will experience symptoms in the gastrointestinal system as well as the face and skin.

Common signs of an allergic reaction include:

  • Itchy skin
  • Sneezing
  • Coughing
  • Vomiting
  • Diarrhea
  • Swollen eyes

Cats experience allergies to many things. Fleas are a source of allergies as well as dust. Cats can experience an unpleasant skin condition called flea allergy dermatitis (FAD) with flea exposure [2].

Check out my guide to flea treatment to help fight the war against fleas.

What should I do if I think my cat has an allergy?

If your cat is experiencing repeated symptoms, schedule an appointment with a vet.

To determine the cause of the allergy, vets perform blood and/or skin prick tests. The vet will send your cat’s blood for laboratory examination. Skin prick tests involve exposure to various substances to see if a skin reaction (e.g. swelling, redness, hives) occurs [3].

The vet will prescribe the proper treatment after identifying the offending food or foreign body that causes the allergy. This may involve eliminating food items from your cat’s diet, flea treatment, or medication.

What can I do to prevent my cat from having allergies?

The best thing you can do to minimize the risk of your cat having allergies is to keep your house clean.

This involves thorough vacuuming and dusting to keep the flea population down. In addition, your cat may need a topical flea treatment with consultation with the vet.

Check out our article on the best flea collar to learn more about topical flea treatment.

What ingredients in cat food cause allergies?

About 10% of all cat allergies are dietary-related [4].

The protein in chicken, beef, dairy (e.g. milk and cheese), eggs, wheat (i.e. gluten), and fish are the main culprits [4]. However, your cat can be allergic to even more foods.

Cat’s experience digestive symptoms in contact with foods they are allergic to (e.g. vomiting, diarrhea) [4].

A lot of cat food brands use a wide variety of ingredients, so teasing out the offending substance is a difficult task. This is why seeking the assistance of a vet is the best way to identify the problem and help your cat.

Another method of identifying food allergies or intolerances is the elimination diet. Food intolerance doesn’t involve an allergic reaction (i.e. doesn’t lead to an increase in antibodies) but may lead to unpleasant symptoms such as bloating and fatigue.

What is an elimination diet?

If your vet isn’t able to identify the cause of your cat’s allergies, they may suggest a food elimination diet.

This involves starting your cat on a very simple hypoallergenic cat food with limited ingredients. This may involve the following plans.

Hydrolyzed protein diet

Hydrolyzed proteins reduce the size of protein into amino acids predigestion. The immune system cannot recognize these proteins, and will not produce the antibodies that lead to allergic reactions.

A range of prescription hydrolyzed cat food formulas exist. They require a prescription and are for short-term elimination diet use.

Novel protein diet

A novel protein is an uncommon protein source (e.g. lamb, venison, goat, turkey, duck). An elimination diet may use limited ingredient novel protein commercial or homemade food [5].

Your vet will decide what the appropriate course of action is depending on the situation.

With both approaches, the addition of individual foods (called a food challenge) over a period of 1-3 months occurs. If any negative symptoms occur, removal of the offending food solves the problem [4].

Can allergies be cured?


Once a cat has an allergy, there is nothing that will cure it. Management is the only solution, which involves selecting foods that don’t expose the cat to the offending substance [5].

As long as the cat is not exposed to harmful food, then it is able to live a happy and healthy life.

What cat foods are hypoallergenic?

Cat’s develop allergies upon exposure to a food.

If your cat hasn’t consumed food, it cannot produce antibodies to the protein. That means cats cannot develop an allergy until consuming the food on multiple occasions.

Chicken and fish are the main ingredients in many cat foods. Cats are more likely to be allergic to these common proteins.

Duck, venison, rabbit, goat, kangaroo are usually proteins (called ‘novel proteins’) with limited exposure. This doesn’t mean your cat isn’t able to develop a food allergy to these foods. However, they are suitable alternatives in the meantime until a diet trial identifies the offending food.

These limited ingredient foods are available commercially or through home preparation. There are some cat food brands that do offer limited ingredient meat products which are useful for tackling allergies.

A vet may prescribe a hydrolyzed protein cat food. An elimination diet may require this specialty food. Check with your vet for help determining the right strategy for your cat.

Are cats allergic to milk?

Cats are rarely allergic to milk.

However, cats do experience lactose intolerance after consuming a small amount of milk. The average cat can tolerate 85ml of milk without harm.

Read more about whether milk is bad for cats over here.

What does hypoallergenic cat food mean?

This is food containing a source of protein that gets broken down for easier digestion and reduced allergy risk. Hypoallergenic cat foods require a vet prescription.

These foods are sometimes used by vets for an elimination diet as they contain hydrolyzed protein. Due to the carbohydrate content and other nutritional values, they may not be suitable ‘long term’ foods.

Check out my guide to feeding your cat for amazing health.

What cat food helps with allergies?

Cat food that has limited ingredients and contains novel proteins (i.e. meats less often used in cat food such as duck and kangaroo) is less likely to cause an allergic reaction. If you are looking for high-quality protein source food for your cat, then these products are a great option.

However, your cat may need a prescription diet with hydrolyzed protein formulas to tackle allergies. These foods need vet approval in order to purchase the foods.

Discuss the best available options for your cat with a vet.

Be mindful of food labeling

When looking for a limited ingredient or single protein (novel protein) cat food to give your cat, be mindful of food labeling and the ingredient list.

Many cat food tins will state the flavor, but that won’t be the main ingredient. If a cat food says ‘recipe’, ‘dinner’, ‘nuggets’, ‘entree’, or any other descriptor the ingredients may have foods unsuitable for limited ingredient diets.

What is the best dry cat food for allergies?

A prescription dry cat food containing hydrolyzed proteins is often used for elimination diets.

Dry foods containing novel proteins and limited ingredients may be less likely to lead to allergies in cats.

Hill’s Prescription Diet z/d Skin/Food Sensitivities Cat Food is one food (that needs a prescription) used for food allergies. The food is only needed during an elimination diet and isn’t recommended for regular use.

As for long-term regular dietary use, I recommend ZIWI Peak Air-Dried Cat Food – All Natural, High Protein, Grain-Free & Limited Ingredient with Superfoods. This is a healthy low-carb dry cat food high in nutritional value. This is a great choice for cats.

Conclusion: Best Dry Cat Food for Allergies

In this article, I’ve talked about the best hypoallergenic cat foods in the dry cat food range.

Cats experience food allergies as humans do. Cats can be allergic to many things including dust, fleas, pollen, inhalants, and food. An allergy creates an abnormal immune response which leads to side effects such as sneezing, coughing, runny nose, puffy eyes, and diarrhea.

If you suspect your cat is allergic to food then the first step is to seek the advice of a vet for assistance. They will perform physical and medication examinations to determine the cause of the allergy. It is difficult to identify the true cause of an allergy due to exposure to a wide variety of foods and environmental allergens.

If identified, removal of the food ingredient from the diet of the cat (e.g. chicken) is the only solution. If your vet suspects a food allergy but isn’t able to work out what the trouble food is they may use an elimination diet.

An elimination diet involves the use of either a novel protein diet (a limited ingredient cat food diet designed to reduce the risk of allergies) and/or a hydrolyzed cat food formula. Food trials with individual food items to work out which food is causing the problem.

Hydrolyzed cat food requires a vet prescription to use. Most of these foods are not appropriate for long-term use due to the high amounts of carbohydrates used.

On the other hand, limited ingredient cat foods do not require a prescription and provide nutritional quality. The only difference with these foods is the restriction to novel protein sources (e.g. lamb, rabbit, duck) which don’t get used in a cat’s diet often. These foods are less likely to lead to an allergic response.

If you suspect an allergy, but do not have a vet prescription you can investigate the use of a limited ingredient cat food. However, I recommend always consulting with a vet to rule out environmental causes or other health issues.
