Russian Blue vs Blue Domestic Shorthair Edmonton: Five Telling Traits

Five traits distinguish a purebred Russian Blue from a blue Domestic Shorthair (DSH) look-alike. First, the eyes: Russian Blues have vivid green eyes as adults (kittens are born with yellow eyes that transition over months). Second, the coat: double coat with silver-tipped guard hairs creating a shimmery appearance, plush and dense. Third, the body type: long-legged, slender, muscular, with a triangular head. Fourth, the paw pads: lavender-pink (not grey or black). Fifth, the temperament: reserved with strangers but devoted to family. A cat showing 4 to 5 of these traits is likely a real Russian Blue or near-pure mix. A cat showing 0 to 2 is a blue DSH look-alike.

Usually no. Most blue cats at Edmonton rescues including Edmonton Humane Society, Zoe's Animal Rescue, SCARS, and AARCS Edmonton fosters are blue Domestic Shorthair cats with the right colour and the wrong everything else. They typically have gold or copper eyes (not green), a single short coat (not the double coat with silver tipping), rounder faces, and grey or black paw pads. Foster staff label them as “Russian Blue mix” based on coat colour rather than full breed assessment. For a pet home, this distinction matters less than people think.

For a pet home, mostly no. For show or breeding, yes. The day-to-day pet experience of a blue DSH with the right look is close to a purebred Russian Blue: short coat, no grooming, low-maintenance care. Where the breeds differ in pet ownership is temperament (Russian Blues are more reliably reserved and devoted; blue DSH varies widely) and lifespan (Russian Blues average 15 to 20 years; blue DSH varies more individually). If you want guaranteed temperament and verified pedigree, a TICA or CFA breeder is the right path. If you want a blue cat that looks like a Russian Blue and acts like a pet, an Edmonton rescue blue DSH is the easier and far cheaper option.

Eye colour is genetically separate from coat colour. The Russian Blue breed standard requires vivid green eyes as adults, and breeders select for this trait across generations. The vivid-green-eyes gene is consistently present in purebred Russian Blue lines. Blue DSH cats inherit eye colour independently of coat colour, so they can have gold, copper, hazel, or occasionally green eyes. Vivid green eyes in a blue DSH are uncommon but not impossible; they suggest the cat may carry Russian Blue ancestry but are not by themselves a guarantee of purebred status.

The Russian Blue has a double coat: a thick dense undercoat plus longer guard hairs on top. The guard hairs are silver-tipped, meaning the very tip of each hair shaft is white or silver while the lower portion is slate-blue. The silver tipping creates a shimmering effect as the cat moves, sometimes described as a halo or sheen. The double coat itself feels plush and dense, distinct from the single short coat of a blue DSH which feels flatter and less dense. The silver tipping is genetically controlled and consistently present in purebred Russian Blues but not in standard blue DSH cats.

Russian Blues are more reliably reserved with strangers, more devoted to primary caretakers, and slower to bond than blue DSH cats. The breed temperament is consistent across individuals because TICA and CFA select for it. Blue DSH personalities vary widely from outgoing and social to extremely shy. For an Edmonton adopter who specifically wants the Russian Blue temperament profile (quiet, dignified, devoted, slow to warm up), a purebred or near-pure cat is more predictable. For an adopter who is flexible on temperament, a blue DSH is the easier and cheaper path.

Russian Blues commonly live 15 to 20 years, on the long end for any cat. Blue DSH cats average roughly the broader cat-population lifespan of 12 to 18 years, but individual variation is wide. The breed-protective effect from limited inbreeding bottlenecks contributes to the Russian Blue's longer average lifespan. A specific blue DSH may live just as long as a Russian Blue, but the breed average is in favour of the purebred.

Yes, broad genetic panels like the ones offered by UC Davis VGL can identify breed ancestry components. The result tells you whether your cat carries genetic markers associated with Russian Blue ancestry. It does not give a registry-recognised pedigree (you cannot use the test result to register a cat with CFA or TICA), but it answers the curiosity question. The test runs roughly $80 to $200 plus shipping. For pet purposes, this is optional; for adopters who specifically want to know, it is informative.

Visually yes, distinct breeds. The Korat (Thai origin) is smaller than the Russian Blue, has a single coat without silver tipping, and has heart-shaped head with green eyes that develop later than a Russian Blue. The Chartreux (French origin) has a wool-like double coat, copper or gold eyes (not green), and a more robust body type. Korat is extremely rare in Edmonton rescue; Chartreux is also rare. Most shelter cats marketed as “blue cat” in Edmonton are Russian Blue mixes or blue DSH, not Korat or Chartreux. A British Shorthair in blue colour is a different breed entirely (stockier, plush single coat, gold or copper eyes, round face).

It usually means the cat has the blue coat colour and possibly some other Russian Blue trait, with the rest being Domestic Shorthair or unknown ancestry. Foster homes label based on visual impression rather than verified pedigree because most rescue cats arrive without parental history. “Russian Blue mix” is a directionally honest label that says “this cat has Russian Blue characteristics but no documented pedigree.” Most cats labelled this way at Edmonton rescues are predominantly blue DSH with possibly some breed influence. The label is useful for adopters searching for the look; it is not a guarantee of breed temperament or lifespan.

Two paths. First, watch Edmonton rescues monthly and apply quickly when a strong-looking purebred candidate posts; this is rare but happens. Second, contact a TICA or CFA Russian Blue breeder for a kitten waitlist; expect 4 to 12 months wait and $1,500 to $3,500 price. Specialty Purebred Cat Rescue in the US occasionally has Russian Blue placements with cross-border transport to Canadian adopters. For most Edmonton adopters wanting the look and most of the personality, a blue DSH from rescue at $300 to $500 fully vetted is the realistic and far cheaper answer.

For most Edmonton adopters, yes. A blue DSH from Edmonton Humane Society or Zoe's Animal Rescue with the right look delivers what most adopters actually want: a short-coated blue-grey cat that needs minimal grooming, fits in apartments and condos, gets along with a quiet household, and lives indoors. The trade-off is less predictable temperament and somewhat shorter average lifespan. For show or breeding ambitions, purebred Russian Blue is required. For pet companionship, blue DSH is the easier path and the cat that would otherwise stay in care leaves the system.
