For Cats, It’s on the Tongue
Cats and dogs cause allergies in completely different ways. When it comes to cats, proteins in the saliva tend to be a major cause of allergy symptoms. Since your feline friend likes to stay clean by licking, all of that saliva ends up on your cat’s fur as well. When it dries, the proteins are released into the air you breathe.
The protein causing the most problems is Fel d 1. Fel d 1 is particularly sticky, meaning it can attach to surfaces where cats have never been; for example, inside offices, schools, and other public places carried there by cat owners. Then again, places where tabbies live have the highest concentration of the offending protein. Even if a feline is removed from a home, it can take several months for its proteins to decrease in carpets and as long as five years for them to decrease in a mattress. Encasing the mattress may be your best bet in such situations.
While all felines shed the protein, some shed more than others. Male tomcats who are not neutered shed more proteins than female cats because their testosterone stimulates the production of the protein. Cats who have mites or ticks are also more likely to spread their proteins because they bite and groom their skin more frequently. So neutering your pet and keeping it free from irritating infestations can be helpful steps. Bathing your tabby is also useful. Kittens are usually more accepting of this, but mature cats can also be gradually accustomed to this cleaning process.
