Russian Blue People who suffer from cat allergies but love cats are often advised to look into Russian blues as possibly hypoallergenic. Unlike many of of the cats on this list that are incidentally hypoallergenic due to the nature of their fur not shedding in the normal way, Russian blues actually produce less of the glycoprotein Fel d 1, the very substance to which people are allergic. Also one of the most friendly cats.
Siberian Well known for its long, remarkably shaggy fur, the Siberian is probably not the first breed to come to most people's minds when trying to think of possibly hypoallergenic cat breeds. But like Balinese cats and Russian blues, many Siberians seem to produce less Fel d 1 protein than regular cats. Some allergy sufferers with extreme allergic reactions to cats have reported no symptoms at all even when surrounded by many Siberians.
