Russian Blue
Anecdotal evidence suggests that the Russian Blue may be better tolerated by individuals with mild to moderate allergies. There is speculation that the Russian Blue produces less glycoprotein Fel d 1, one source of cat allergies. The thicker coat may also trap more of the allergens closer to the cat's skin. Glycoprotein is one source of cat allergies, but this does not mean they are suitable to be homed with people allergic to cats as they will still cause the allergy to be affected, only to a lesser degree for short periods of time.
