<P> Russian Whites and Russian Blacks were created from crosses with domestic white cats which were allegedly imported from Russia . The first line was developed by Frances McLeod (Arctic) in the United Kingdom during the 1960s and the second line produced by Dick and Mavis Jones (Myemgay) in Australia in the 1970s . By the late 1970s, the Russian White and Russian Black colors were accepted by cat fanciers in Australia as well as in South Africa and now also in the United Kingdom as Russian cats (in different classes). However, the Cat Fanciers' Association and FIFe does not recognize any variation of the Russian Blue . </P> <P> The Russian Blue has bright green eyes, pinkish lavender or mauve paws, two layers of short thick fur, and a blue - grey coat . The color is a bluish - gray that is the dilute expression of the black gene . However, as dilute genes are recessive ("d") and each parent will have a set of two recessive genes ("dd") two non-CPC Russian Blues will always produce a blue cat . Due to the breeding with Siamese after World War II, there are colorpoint genes floating around . If two carriers are bred together, then they will produce a litter of mixed colors--solid blue or white with blue like a Siamese . People call these CPC cats "colorpoint", "whites" or "pointed" Russians . In most registries, one cannot register, breed or show a colorpoint Russian . </P> <P> The coat is known as a "double coat", with the undercoat being soft, downy and equal in length to the guard hairs, which are an even blue with silver tips . However, the tail may have a few very dull, almost unnoticeable stripes . The coat is described as thick, plush and soft to the touch . The feeling is softer than the softest silk . The silver tips give the coat a shimmering appearance . Its eyes are almost always a dark and vivid green . Any white patches of fur or yellow eyes in adulthood are seen as flaws in show cats . Russian Blues should not be confused with British Blues (which are not a distinct breed, but rather a British Shorthair with a blue coat as the British Shorthair breed itself comes in a wide variety of colors and patterns), nor the Chartreux or Korat which are two other naturally occurring breeds of blue cats, although they have similar traits . </P> <P> The Russian Blue is a curious and tranquil animal . They are known for their friendliness and intelligence and are somewhat reserved . They have been known to play fetch, open doors and are sensitive to human emotions . They enjoy playing with a variety of toys and develop loyal bonds to their loved ones and other family pets . They are generally considered to be a quiet breed but there are always exceptions . They are clean animals that are normally reserved around strangers, unless they are brought up in an active household . Many Russian Blues have been trained to do tricks . They can also be fierce hunters, often catching rodents, birds, rabbits, small mammals, or reptiles . </P>
