Coat and looks how to spot one

semi-long, dense, silky double coat

A long, graceful and well-muscled cat with a wedge-shaped head. Its medium-long silky coat is blue with silver-tipped guard hairs, which gives the fur a soft, misty shimmer. The coat is fuller in winter than in summer.12

Coloursblue with silver tippingeyes: yellowish green to vivid green12

Personality what they are like

A calm, sweet and loyal cat that becomes very attached to its own people and often follows them from room to room. It can be reserved with strangers and prefers a steady, predictable home.23

Daily activity how busy a day looks

Moderate. Enjoys play that imitates hunting, such as stalking and pouncing, and likes climbing and retrieving, but is also happy with quiet time.23

Grooming and care the hands-on bits

Despite the long coat, care is simple: comb or brush about once a week to remove loose hair and keep the coat tidy. Regular tooth brushing is recommended.23

Home where they are happiest

Does best in a quiet, predictable household with a routine.3

Company who they like around

Forms strong bonds with family members; may be shy with visitors and young children at first.23

The story where it all began

American breeder Cora Cobb started the breed with Siegfried (born 1984) and Brunhilde (born 1985), longhaired blue cats from ordinary domestic parents. Her aim was to recreate the look of the longhaired blue cats that came from Russia around 1900. In 1993 a Dutch breeder imported a Russian longhaired blue, which helped show the longhair gene occurs naturally in Russian Blue lines and linked Russian and American breeding.12
