What Are Cat Allergens?

An allergy to cats can be caused by any number of various aspects of cat physiology and behavior. Allergens produced by cats include their dander, fur, saliva, urine, and litter dust. If you find that you are allergic to your fuzzy little friend, it may be possible for you to isolate and control the allergen that is causing the problem. A few changes in grooming or litter box care could go a long way in reducing your cat allergy.

  1. Saliva

    • Cat saliva is the most common cause of pet allergies in humans. Cats groom themselves by licking their fur, which becomes covered in their saliva. The organic chemicals in cat saliva can cause an allergic reaction in humans. If you believe that your cat's saliva might be the source of your runny nose, try bathing it frequently using a moisturizing, pet-friendly soap.

    Dander

    • Just like humans, cats shed skin. These flecks of dead skin, called dander, can be very irritating to the human immune system and prompt an allergic reaction. It doesn't help that the dander is often coated in saliva as well. Cat dander is by far the hardest allergen to control. If you suspect that dander might be the problem, do not bathe your cat. This will only dry out its skin and cause more of it to flake off. Instead, groom them frequently to slough off the dead skin. Some pet stores sell sprays that can be used to reduced dander as well.

    Urine

    • Cat urine contains a protein that provokes allergic reactions in many people. Although you can't stop your cat from using the litter box, cleaning it frequently and using high quality-litter will help alleviate your allergic reaction. The best litters are highly absorbent, do not produce as much dust, and reduce smell. If you use litter that effectively absorbs the urea, it will be less likely to get on your cat or in the air. This will reduce your exposure to the allergen.

    Fur

    • Cat fur is very rarely the cause of an allergic reaction. However, mold spores, pollen and other allergens can collect on the fur and cause an allergic reaction that is unrelated to the animal itself. If you find that you are only allergic to specific cats, this may be why. To control this, use a grooming comb on your cat frequently and do not allow its fur to collect on furniture or linens.

    Litter

    • Although it is hardly the cat's fault, the litter dust that collects on its feet and fur can cause an allergic reaction in some individuals. The solution for this type of allergy is quite simple: Switch litter brands, preferably to something that produces less dust.
