5 Common Cat
Food Allergy Symptoms
Much like humans, cats can get allergies, too. An allergy is
any reaction that’s discomforting and induced by the immune
system over-reacting to food, something the cat inhaled or
something in the environment.
The immune system, of course, is needed to protect against
bacteria, foreign proteins, viruses, and other troublesome
substances that enter the cat’s system. Of course, it doesn’t
mean it only reacts to dangerous stuff. The immune system
response can sometimes be triggered by things not usually
That’s how you can end up allergic to house dust, insect
bites, pollen, wool, powder, even feathers too. Triggered, this
usually results in a bout of itching, sneezing, coughing,
vomiting or diarrhea in humans. The same symptoms can occur in
For cats to become allergic to anything, they must be
exposed to whatever it is that induces the reaction a couple
times minimum. Hypersensitivity reactions can occur and there
are two different types. The first one takes place post
exposure and almost instantaneously which often leads to itches
and hives. The other is a more delayed reaction that can
produce the same itchiness but hours and in some cases, days
after being exposed.
One of the more common allergies concerns for pet owners is
to food. While true food allergies are not very common in cats
(food allergy accounts for just 10% of all pet allergies), it
can still happen. Cat food allergies can strike the cat at any
Corn, wheat, soy, fish, and chicken are common allergens
apparently. And that’s not all. Allergies to pork, beef and
even dairy products and eggs may emerge as well. If you
noticed, these are practically all the ingredients in cat food.
That means your cat is likely exposed to them every day.
Some of the more common cat food allergy symptoms
- intensely itch rash on the head, neck, back, sides of
the body, legs and anal area
In some cases, the food allergy symptom may be isolated to
just the ears. They will then become inflamed followed by a
nasty discharge that’s moist.
If you see your pet showing any of these cat food allergy
symptoms, it’s best to contact your vet. Unfortunately, the
only way to see if the allergy is caused by his diet is to
perform a food trial. This means taking out the suspected
allergen from the diet for around one to one and a half
We then proceed to the next step which is to expose your cat
to the allergen again. This may seem a bit cruel but it’s
something that must be done to be able to identify that the
suspected allergen is in fact the cause of the symptoms.
After determining the exact cause of the allergy, it’s time
to switch your cat to a hypoallergenic diet. Note however, that
some pets may develop food allergies in 1 to 3 years. That
means a flare-up of itchiness can occur again and another food
trial must again be done.
When this happens, you can try feeding the cat home-cooked
meals. Or, as always, just contact the professionals (that
would be the vet) and work out a new natural diet that would
work better with your cat.
