Although cats in the wild may not consume grains, they provide numerous health benefits, such as energy and vitamins.

Buyer's Guide

There is a great deal of information and disinformation regarding grain-free diets for cats. However, we want to assist you in making an informed decision when shopping for cat food, so that your cat can acquire the nutrients necessary for a long and healthy life.

Are grain-free foods for cats superior?

There is no nutritional data to support a grain-free diet, despite the widespread belief that cats shouldn’t consume grains because they don’t in the wild. A healthy cat may digest a diet containing grains without negative consequences on its body. It enhances their energy levels and gives them with essential nutrients without reducing their longevity.

Grain contains calcium, thiamine, iron, folate, riboflavin, and niacin in addition to dietary fiber, which reduces hairball formation. Grains provide your cat with important fatty acids, vitamins, and minerals.

People once believed that grain-free diets were superior since they were sold by specialists and are sometimes characterized as “holistic.” Grain-free diets are important if your cat’s health necessitates it, but if your cat is healthy, grain-free cat food is not required. Whole grains are an economical and healthful addition to cat food; they are not just fillers.

When Should You Feed Your Cat a Diet Free of Cereal Grains?

Although grain-free cat food is not required for healthy cats, there is a place for these foods in the diets of cats who require them.

If your cat has inflammatory conditions, irritable bowel syndrome, grain sensitivities, allergies, or difficulty digesting grains, your veterinarian may recommend switching to a grain-free diet. In these instances, grain-free cat food is your best option, as it may decrease or eliminate your cat’s symptoms.

Even while grain-free cat food may have a link to heart disease in dogs, there is little data to suggest that it is harmful to your cat’s health. However, the price may be a bit higher.

How to Determine if Your Cat Is Allergic to Grains

Although it is uncommon, some cats have an allergy to the components in their diet. Most of the time, their poor digestion and adverse reactions to food are caused by the presence of animal protein rather than carbs. Frequently, cats are allergic to chicken, meat, fish, and any other protein they have consumed for an extended period.

Veterinarians frequently advise beginning the transfer of a sensitive cat to diets containing novel proteins, as these foods typically contain animal proteins the cat has never consumed and should not induce an allergic reaction. If your cat continues to experience an allergic reaction to its food, your veterinarian may recommend a hydrolyzed protein diet.

However, a veterinarian can perform tests to diagnose your cat with a grain allergy, allowing you to better manage its diet and symptoms.

Itchiness, bald patches, hair loss, vomiting and diarrhea, frequent grooming, red and inflamed skin, blisters, scabs, and “hot spots” might be symptoms of a grain allergy. If you have observed these signs in your cat, do not allow the condition to worsen. Veterinarians are in the best position to assist you with both initial therapy and long-term maintenance.

What Does Grain-Free Cat Food Entail?

True to its name, grain-free cat food is a diet devoid of grains. These dishes do not contain barley, rice, oats, corn, or wheat. However, they are frequently substituted with other carbs, such as sweet and regular potatoes and a variety of legumes.

These alternative components frequently match or exceed the number of carbs in your cat’s food, so continue to measure out and monitor your cat’s food intake, as grain-free cat feeds are not always conducive to weight loss.

Gluten is found in the protein of certain grains, hence it is absent from grain-free cat food. Gluten allergies are common in humans, but they are uncommon in cats and normally not cause for alarm.


Here is a brief overview of BestForPets (bestforpets.org)’s top choices for the best grain-free cat foods in the UK. The Thrive Cat PremiumPlus Dry Food is the most cost-effective option. The premium choice is the Lily’s Kitchen Adult Delicious Chicken and Healthy Herbs Dry Complete Cat Food.

Arden Grange Kitten Food is the finest option for kittens, although Dr. Elsey’s Cleanprotein Chicken Formula Dry Cat Food is also a good option. Any of the cat foods would be an excellent choice for your cat.
