- Medium to lighter shade with a distinct and visible silver sheen.

Medium-sized, elegant cat with distinctive blue-gray double coat and emerald green eyes. Known for reserved but affectionate nature.
Natural breed originating around the Russian port of Arkhangelsk. Also called Archangel Blue. Nearly extinct after WWII but rebuilt using Scandinavian and British cats. Known for hypoallergenic qualities.
Typically 3.2-6.8 kg and 25-30 cm at the shoulder — published as one range rather than separately for males and females.
Generally described as active, dependent, easy going, gentle, intelligent, loyal, playful, quiet and reserved.
That is the breed in general, not a promise about one animal. Ask the breeder what their own line is like, and meet the parents before you decide.
Breed reference from The Cat API.
Drawn from sources rather than written as an opinion — cited health research, the registry’s own standard, and peer-reviewed longevity. FIFe breed standard; The Cat API. One breeder’s animals can differ from any of it, and an empty column means we hold nothing for that side rather than that there is nothing to say.

Preferred, permissible, undesirable and disqualifying are FIFe’s own words about the breed. They describe what the standard asks for — not an assessment of any individual dog, and not ours.

Breed-level information from The Cat API. It describes the Russian Blue in general; any individual animal can differ.
Known hereditary risks for the Russian Blue breed, and the specific documentation to request from any breeder before paying a deposit. A responsible breeder will have these readily available; deflection is a red flag.

Health checklist (PDF)A pedigree study of Russian Blues found bilateral cataracts in around a third of the cats examined — usually small and not affecting vision, but occasionally more extensive and causing visual impairment or blindness. No causative gene has yet been identified, so there is no DNA test; screening relies on a veterinary ophthalmologist examining the eyes directly.
What to ask for
No DNA test exists (the causative gene has not been identified). Ask for a veterinary ophthalmologist's slit-lamp examination result for both parents.
This is where Russian Blue owners’ own photographs will go, from the pet profiles they keep here. Nobody has added one to a public page yet.
A photograph in a pet profile stays private to its owner. We will not put one here unless they ask us to.
That is not the same as none existing. Publishing a litter is part of a breeder's subscription here, so a Russian Blue breeder can have a litter and no listing — ask them directly.
