While no known cat breed is 100 percent non-allergenic, the Siberian cat is considered hypoallergenic because it is very unlikely to cause major allergic reactions. Siberian cats have long hair, but they do not produce as much of the Fel d 1 protein as other cats, notes PawNation.
Despite their long-hair coats, many severe allergy sufferers are able to spend time with Siberian cats without any severe allergic reactions. Siberians are ideal choices for allergy sufferers who long to spend time with an affectionate cat. They are very personable, quiet and intelligent, making them excellent companions. Siberians are also playful.
