Allergies in Cats

by catfood

People can have allergies to many different things, including cats, but cats can also have other allergies. Since antibodies are made to warn the body that something is attacking it, they are frequently used to fight things like infections. Knowing about the allergies that cats can experience, how to tell if your cat has them, and how to manage them can help you avoid problems.


What Do Allergies In Cats Mean?

A cat’s immune system will react by producing antibodies if it is exposed to anything it is allergic to, even if the object is not dangerous. Cats can experience some very significant, uncomfortable, and even fatal allergic reactions. When antibodies are produced in response to allergens, the cat’s immune system may respond. This reaction and the symptoms it produces are therefore frequently referred to as allergies.

Allergies in cats can range in severity from hardly annoying to potentially lethal.


Cat allergic reactions

  • Itching
  • Hairloss
  • difficulty breathing
  • Redness or itching of the skin
  • Swelling
  • Sneezing
  • Vomiting up or gagging
  • Coughing
  • Wheezing
  • Watery eyes or a nose
  • Diarrhea
  • Grabbing the tail and biting it

In cats with allergies, the more severe symptoms have a greater impact on breathing. Because of swelling in the face, nose, or throat brought on by the body’s response to an allergy, cats may have trouble breathing. In cats who already have asthma, the swelling may become serious if it is not treated quickly away, leading to coughing, gagging, wheezing, collapsing, and ultimately death. Since oxygen is necessary for life, a cat’s inability to breathe due to allergies poses a threat to its survival.

In addition to having trouble breathing, a cat that is allergic to something may also experience runny eyes, a runny nose, and sneezing. It’s possible that allergens that irritate the mucous membranes are what causes these symptoms.


Other signs of allergies include scratching at the paws or tail, hair loss, skin redness and irritation, and itching. These symptoms are typically seen in cats who have allergies to fleas, food, and other environmental elements. In an effort to feel better, a cat will scratch and nibble on its own skin because allergens irritate and inflame the body. Even open wounds and hair loss could happen from this.

Finally, digestive system irritation and pain can occasionally be brought on by allergies. This could cause vomiting and diarrhea.

Cat allergy triggers

Many items, most of which are conveniently found in and around our homes, might cause allergies in cats. The thing that is triggering a cat’s allergies may sometimes be difficult to get rid of as a result.

  • Pollens: Tree, dust, grass, weed, mold, and mildew pollens can cause allergies in cats. It might be difficult to manage certain environmental allergies.
  • Food is the third most common factor in allergic reactions in cats. Cats can have allergies to a wide range of foods, but those high in animal proteins—such as chicken, beef, dairy, fish, and eggs—are the most common offenders.
  • Fleas: Cats with flea sensitivity usually have allergic reactions from flea bites, including itchiness, redness, and hair loss. Fleas can even infest indoor-only cats.
  • Treatment: Shampoos, flea medicines, and other treatments may produce negative side effects in cats.
  • Cleaning products: Detergents, floor cleaners, and disinfectant sprays may cause cats to develop sensitivities.
  • In addition to being annoying in and of itself, strong colognes and perfumes can cause allergies in some cats. Allergens that are breathed frequently cause cat allergies.
  • Some cats are allergic to smoke, including smoke from cigarettes and other sources, much like some people are to other inhalants.
  • A cat may be allergic to a variety of surfaces, including those composed of cloth, rubber, or plastic. Certain beds, food bowls, and floor mats may cause problems for cats who have sensitivities to those items.

How to Spot Cat Allergies

It could be difficult to determine what a cat is allergic to. Elimination diets and exclusion trials with various cleaning products, meal plates, bedding, and medications may be necessary if the cause of an allergic reaction is not readily evident. Various blood and skin tests are available to determine which allergens a person is allergic to.


Depending on the kind of allergy your cat has, the course of treatment may vary. It is preferable to get the allergen out of your cat’s environment, although this is obviously not always possible. Your cat may occasionally require long-term medication or allergy treatments, depending on the degree of the symptoms and the underlying cause of the allergy.

How to Prevent Allergies to Cats

There is no way to prevent cats from developing allergies, but there are several ways to limit their exposure to allergens. By keeping your home clean, using dust-free, unscented cat litter, abstaining from excessive deodorizer or perfume use, quitting smoking indoors, using regular flea preventatives, and using metal or ceramic food and water bowls, you can reduce the likelihood that your cat will experience an allergic reaction. If your cat displays allergic symptoms, it’s crucial to see a veterinarian.
