Russian Blue
The Siberian (along with the Russian Blue, Balinese, Cornish Rex, Sphynx and several others) produces less Fel d 1 than other cat breeds and, while it is certainly not completely so, is often called hypoallergenic. A research study of Siberian cats native to the area of Russia from which the breed stock originated confirmed the subjects produced less Fel d 1 (the strongest among the eight known Fel d allergens produced in cat saliva, therefore, is deposited on their fur when they groom themselves) than non-Siberian cats.
