A cat intolerance test will look for a sensitivity to food items or environmental and artificial factors.

If you suspect your cat is suffering with an intolerance, an intolerance test could provide you with some valuable pointers.

Some intolerances can have a detrimental and destructive impact on the lives of cats if left undetected. Other cats won’t show any symptoms but could be suffering in silence.

My brother-in-law’s cats were suffering with dry, flaky skin that was red and inflamed. He thought it was the result of the cats playing too boisterously or licking each other too much.

However, his vet recommended a cat intolerance test and to his surprise, the cats (who were brothers) were suffering with an intolerance to grains in their diet.

As a result, my brother-in-law sourced grain-free cat food and their skin looks much healthier and the bald patches gradually disappeared.

Most cat intolerance tests will require pet owners to send a sample of their cat’s hair to the company’s laboratory for testing. Once pet owners have collected a sample of the appropriate size, you’ll have to place it in a sealable bag and send to the lab.

It’s a good idea to speak to your veterinarian to discuss your results before you decide to make any changes to their diet or your home.

What Causes Cat Intolerances?

Cats can have an adverse reaction to both food items and non-food items.

Your feline friend could have an intolerance to a protein source in their diet or your kitty could have a reaction to a household cleaning products.

Some cats could have an adverse reaction to other pets such as hamsters and rabbits.

It’s worth remembering that cats can also be intolerant to environmental factors outside, such as plants or trees in your garden.

Fetch by WebMD write on their website that cats can have allergic reactions to the following substances: trees, food, fleas, prescription drugs, perfumes, cleaning products, cigarette smoke, fabrics and rubber and plastic materials.

You’ll find that one of the most common ways cats are exposed to allergens is their diet.

By learning about your cat’s intolerance to a particular food type, you could choose to order from a cat food company who will tailor their recipes to meet your feline’s needs.

You can work with some of the best cat food delivery companies in the USA to ensure that your cat’s meals won’t contain any offending foods once you’ve got the results from your cat intolerance test.

Some traditional cat food brands don’t clearly list their ingredients, which is one of the reasons why cat food delivery companies can be useful.

Allergy Test Vs Intolerance Test

You may be wondering what’s the difference between a cat allergy test and a cat intolerance test.

Generally speaking, the reaction to allergies is more severe than intolerances and usually occurs immediately.

The Pet Food Manufacturers’ Association in the UK explain the difference between a food allergy and a food intolerance where pets are concerned:

Food allergies and intolerances are two different conditions which often have similar symptoms. They are both examples of adverse food reactions, however food allergies involve the animal’s immune system while food tolerances do not.

However, it’s important to note that the difference between a food allergy and a food intolerance is not always easy to define.

It’s a good idea to speak to your veterinarian to lean more about the difference between a food allergy and a food intolerance.

What Intolerances Can You Test For?

Most cat intolerance tests will analyse a number of food and non-food items.

The test will indicate which foods and other allergens could cause an adverse reaction in your cat.

Some examples of food that can be analysed include cod, duck, halibut, milk, maize, potatoes, rice, wheat/wholegrains and much more.

Non-food items include bees, dust, hamsters, sheep’s wool and willow.
