What triggers allergies in cats ?

Best cats food for allergies

When a certain substance, normally called an allergen, gets inside a cat’s body, the immune system will produce antibodies. These antibodies then signal other immune cells to attack the allergen even if it is not actually harmful or toxic.

Cats can have allergies due to three main things. These are food, fleas and environmental substances such as pollen, dust, cleaning solutions, fabrics and even cat litter. Sometimes cats can have multiple allergies at once.

Food allergies are somewhat uncommon when compared with other allergies. It affects only about 0.1% of cats. Food allergies are the third most common type of allergy seen in cats.

What causes an allergy to develop is not exactly clear, but the cats who have one will develop it between ages 2 and 6. Both male cats and female cats seem to be affected equally, while certain breeds may have greater risks developing them.

Symptoms of cat allergies due to food

Cats show certain symptoms when they are allergic to food. Some of the most common symptoms are:

  • Dull looking coat
  • Foul smelling skin and coat
  • Excessive scratching and itching
  • Dry, flaky, red, inflamed and irritated skin
  • Sneezing, coughing, wheezing, snoring and other respiratory signs
  • Runny nose and eyes
  • Frequent chewing at paws
  • Fatigue, lethargy and low energy

These symptoms of food allergy should not be confused with the ones due to food intolerance. While an allergy stimulates a specific immune system reactivity and the main symptoms are related to the skin, food intolerance leads to gastrointestinal issues such as vomiting and diarrhea.

How to find if your cat is allergic to food

Diagnosing an allergy can be somewhat difficult. There is no specific test to help find out what exactly is causing an allergic reaction in cats.

The best thing to do is contact your vet and get help to determine the cause. Most of it will come down to trial and error. You can remove certain food items from their diet and see how it affects them.

This eliminating diet can help you determine what affects them. Sometimes certain ingredients can be added to the diet as well.

Once you determine the ingredient, remove that from their diet and never give them that again.
