Russian Buff

Russian Buff has only recently been accepted for a standard, whereas Russian Topaz (it’s agouti counterpart) has been standardised for much longer. This is because a lot of selection is required in order to get a Russian Buff to look visually distinct from a standard Buff. At this time there are not thought to be any breeders specifically working on Russian Buff, but they come up in Russian Topaz litters.

Genetics – this is a self rat, with two copies of the Red Eye Dilute gene and 2 copies of the Russian Blue gene.

NFRS Variety Standard: To be a pale greyish beige. Faint light speckling or a subtle ticked effect (heathering) is usual for this variety and is not a fault. Colour to be level throughout. Not to be confused with standard Buff or Platinum. Belly colour to match top, undercolour light greyish beige to the skin. Coat to be short and thick – a long coat or a coat similar to that on other varieties (excluding rex) to be a serious fault. Eyes dark ruby to black.
Faults: Dark, dull or too warm top colour. Light ruby eyes.
Severe Faults: Very pale or dark patches or prominent white eye circles.
