Choosing the Best Grain-Free Cat Food in Canada: A Buyer's Guide

You’re not alone if you’re feeling overwhelmed by the variety of grain-free cat food alternatives available.

Grain-free diets are required for some cats, however you should not change your cat’s diet without first consulting with your veterinarian.

Grain-free diets are not necessary for all cats, so be sure the switch is beneficial to your cat’s health first. If your veterinarian has advised you to avoid grains for your cat, here’s what to look for in grain-free cat food.

  • Look for cat food that is nutritionally balanced. Whatever cuisine you choose should be “balanced and complete.” It should adhere to AAFCO nutritional recommendations for cats and be age-appropriate for your cat. Kittens, for example, require different nutrition than elderly cats, and their food should reflect this.
  • Take into account your cat’s food preferences. Keep in mind if your cat prefers wet or dry food, for example. Perhaps your cat is finicky and dislikes chicken-flavored kibble. It makes no difference how healthy a food is if your cat refuses to eat it.
  • Make the transition gently. When changing your cat’s diet, combine the new and old foods and gradually increase the amount of new food. This will allow your cat’s body and digestive system to adjust to the new substances without producing any undesirable side effects.

Is a Grain-Free Diet Necessary for Your Cat?

Grain allergies in cats are uncommon, although they do occur. Symptoms of grain allergies include:

  • Red, itchy skin
  • Bald patches or hair loss
  • Skin that is scabby and scaly

If you feel your cat has an allergy, take them to the clinic for testing to discover if their diet is to blame.

It is also possible for cats to have a sensitivity or intolerance to grains, and some owners report that feeding their cat a grain-free diet reduces vomiting bouts.

The Benefits and Drawbacks of Grain-Free Cat Food

There are several benefits to giving your cat a grain-free diet, which include:

  • Grain is commonly added as a “filler” in cat meals to enhance carbohydrate content and because wheat, rice, and corn are relatively affordable. In grain-free foods, these are frequently replaced with higher-quality components.
  • In the wild, cats would not consume grains. Grain-free cat food is more similar to what a cat’s natural diet would look like.
  • If your vet has diagnosed your cat with a grain allergy or sensitivity, a grain-free diet may be required to avoid an undesirable reaction.

Disadvantages of a grain-free diet include:

  • When grain is removed from cat food, it must be substituted with another substance. As a result, grain-free food is frequently higher in fat and calories than grain-containing food. This is significant since it may result in your cat getting overweight.
  • Grain-free foods are frequently more expensive than conventional foods.

Grain-Free Diet Myths and Misconceptions

There is nothing inherently wrong with providing your cat a grain-free diet.

Grain-free cat food was once reserved for cats with allergies and food intolerances, but it has grown in popularity in recent years.

This popularity has mirrored that of grain-free and low-carbohydrate diets for humans.

Do all cats require a grain-free diet? No, most of them do not, although cats are obligate carnivores. Meat is the most important part of their diet.

There’s nothing wrong with cat food as long as it covers their protein, vitamin, mineral, and calorie needs in a nutritionally complete recipe.

Do Grain-Free Diets Increase the Risk of Heart Disease?

While there has been a correlation established between grain-free dog food and canine heart disease, no evidence has been found to suggest that cats are at danger.

In 2018, the FDA initiated an examination into grain-free pet meals, which discovered that grain-free diets pose no health risk to cats.


When looking for grain-free cat food, it might be difficult to know which meals are the best.
