What makes people allergic to cats?
You might be tempted to think that cat fur triggers allergic reactions. However, the cat’s saliva, sebaceous glands, and dander (dead skin) are the culprits.
It seems that these substances are rich in a protein known as Fel d1, and if you are sensitive to this protein, you might experience an allergic reaction.
If this protein touches your eyes, nose, or mouth, it’s a done deal for your allergies. As cats constantly groom themselves by licking their fur, the Fel d1 protein molecules that naturally appear in their saliva are transferred to their fur and skin.
Saliva dries, and those tiny protein molecules get in the air as the cat moves around. Moreover, if you pet your kitty, the Fel D1 protein can get on your hands. This small protein can stay in the air for longer periods of time.
It can land on furniture, carpets, and even clothing. For those of you who are extra sensitive to proteins, your symptoms might be triggered just by entering a room.
