Blue is a coat color, not a breed: a blue-coated cat is not automatically a Russian Blue. Four breeds are especially associated with blue coats—the Russian Blue, Chartreux, Korat and Nebelung—while British Shorthair, Burmese, Oriental Shorthair and Persian cats can also be blue among other colors. The breed profiles and standards cited here are from cat organizations, not veterinary reviews, so this guide is not vet-verified.
What does “blue” mean in cats?
In cat-breed descriptions, “blue” refers to a gray coat color, sometimes with a distinctive silver effect. It does not identify a cat’s breed on its own. Breed identification depends on more than coat color, and a blue domestic cat may not belong to any of the breeds below.

The shade and texture vary. Russian Blues, Korats and Nebelungs are described with silver tipping, while Chartreux coats range from ash to slate gray. Blue may be a defining color for a breed or just one accepted variety.

How can you tell a Russian Blue from a Chartreux?
Both breeds have short blue coats, but their official descriptions point to useful differences. The Russian Blue has a short, dense coat with silver tipping and green eyes in CFA’s description. The Chartreux is described by CFA as blue only, with shades from ash to slate; TICA notes its dense, woolly coat and orange-toned eyes. Coat color alone cannot confirm a cat’s breed.
What is distinctive about the Korat and Nebelung?
Korat
The Korat and Thai Cat Association calls it “the blue cat of Thailand.” The CFA standard specifies silver-tipped blue all over, and the association describes a glossy, close-lying coat that is short to medium in length. Its short-to-medium coat differs from the Nebelung’s semi-long coat.

For Korat, British Shorthair, Burmese and Oriental Shorthair, the cited material does not specify a grooming schedule. A metal comb can be useful for combing, but the appropriate tool and frequency depend on the individual cat’s coat and tolerance.
What do the breed-profile life-expectancy ranges mean?
TICA’s breed profiles list life-expectancy ranges of 10–20 years for Russian Blues, 8–13+ years for Chartreux and 11–16+ years for Nebelungs. These are descriptive breed-profile ranges, not guarantees or clinical predictions for an individual cat.
Are blue cats Russian Blues?
No. Blue is a coat color shared by several breeds, and it does not establish breed identity. A Russian Blue is one particular breed with its own description and standard; Chartreux, Korat, Nebelung and blue varieties of other breeds are distinct.
