Buyer's Guide: How to Choose the Best Allergy-Friendly Cat Foods in Canada

While it comes to allergies in cats, there are a few things to bear in mind when selecting their diet.

First and foremost, ensure that the food does not include any of the allergens to which your cat is allergic.

Second, despite its minimal ingredients, you want to choose a cuisine that is nutritious and enjoyable.

What Causes Cat Allergies?

Cat allergies can be caused by a variety of factors. Flea allergy dermatitis, an allergic reaction to the proteins in flea saliva, is one of the most prevalent.

Dust mites, pollen, and certain foods can also cause allergies. Environmental factors such as cigarette smoke or perfumes can also induce allergies.

The immune system of a cat is in charge of fending off external invaders such as viruses and bacteria.

When a cat is exposed to an allergen, its immune system incorrectly recognizes it as a threat and creates antibodies to combat it.

These antibodies subsequently bind to mast cells in the body, causing histamine and other substances to be released.

These compounds induce allergy symptoms such as sneezing, runny nose, itchy eyes, and a sensitive stomach.

How to Recognize Allergens in Your Cat

Taking a detailed history is the first step in discovering allergens affecting your cat.

This should include when the symptoms first appeared, what the cat is currently exposed to, and any other relevant medical history.

It is also necessary to do a physical examination, giving special attention to the skin and coat.

Allergens can produce a wide range of clinical signs in cats, so it’s critical to work with your doctor to figure out which allergens are causing your cat’s symptoms.

What to Look for in Hypoallergenic Cat Food

There are a few things to look for when purchasing hypoallergenic cat food. First, ensure that the dish is produced with few components.

This indicates that the food has only a few critical ingredients, lowering the likelihood of an allergic reaction in your cat.

Second, look for food that is devoid of additional allergies such as maize, soy, wheat, and eggs. If your cat is allergic to one of these components, avoid meals containing it.


Choosing the proper product for your allergic cat might be difficult.

Purina ONE Sensitive Skin & Stomach Dry Cat Food is our top recommendation because of its full nutrition, affordability, and the fact that it is recommended by numerous veterinarians.

This product, which has many positive reviews, is a terrific place to start.
