Official ICCF Breed Description
Brief Historical Background
The Russian Blue is one of the oldest natural cat breeds originating from Russia. The first mentions of silver-blue cats date back to the Arkhangelsk region, where they were known as “Archangel Cats.” They were prized for their beauty, thick coats, and hunting ability. In the 19th century, cats of this type were brought to Great Britain, where organized breeding began and the name “Russian Blue” was established. In the early 20th century, the breed nearly disappeared due to wars but was restored through careful breeding using European and Scandinavian lines. Today, the Russian Blue is recognized worldwide as a symbol of refined elegance and noble grace.

The body is long and slender, with fine bones and flexible musculature. Legs are long and delicate, ending in small, oval paws. The head is wedge-shaped with a flat skull and straight profile. Ears are large, pointed, and widely set. The eyes are large, slightly slanted, and vivid green—the hallmark of the breed. The tail is long, thin, and tapers smoothly. The overall appearance of the Russian Blue combines refinement, strength, and aristocratic grace.
Important Proportions
All proportions emphasize an elongated, refined, and balanced outline. The body should be slender, longer than it is tall, with light bone structure and good muscle tone. The head is wedge-shaped and proportional to the body, with a straight profile and firm chin. The ears are large, set wide apart, and follow the lines of the face. Eyes are medium to large, slightly almond-shaped, and always a bright green. Limbs are long and slender with neat oval paws. The tail is long, thin, and proportional to the body.
