Instead, the allergic reaction is caused by a tiny protein in an animalâs saliva. Even homes without pets may contain dander. Thatâs because pet dander is sticky and light.
The allergens produced by cats that irritate people with allergies are pet dander and saliva. Pet dander is similar to dandruff and is produced by the skin. Of course, saliva is produced by the cat's tongue and is spread to the fur and skin during cleaning. Even hairless cats produce dander and saliva. Fur can carry the cat dander and saliva so that it comes in contact with people which tends to increase allergic reaction. So, in general cats that shed less may tend to cause less allergic reactions.
