Adult weight reference

3–5.5 kg · 6.6–12.1 lb

This is an approximate editorial reference, not a verified breed standard or a target for your pet. Sex, adult frame, muscle and individual variation affect weight. It does not apply to puppies, kittens or pregnancy.

A Russian Blue inside this range can still carry too much or too little body fat. A pet outside it may simply have a different frame. Ask your veterinary team to assess body condition and muscle before changing meals.

These are broad tendencies, not compatibility guarantees. Meet the individual and ask about their behavior, previous routine and medical needs. A garden does not replace interaction or exercise, and apartment suitability does not mean a pet can comfortably be left alone for a full workday.

Questions before bringing one home

Look beyond the scales

Use gentle hands to feel for ribs and look for a waist from above. Coat thickness can hide shape; avoid relying on appearance alone. Your veterinarian can interpret these observations alongside medical history and changes over time.
