Addictional informatio n (Wiki): The Russian Blue (historically Foreign Blue) is a type or breed of cat that has a silver-blue coat. These cats are known to be highly intelligent and playful but tend to be timid around strangers. They also develop close bonds with their human companions and are highly sought after due to their personalities and unique coat.

The Russian Blue has a lean elongated body and a short, plush, blue-grey coat. The color is a bluish-grey that is the dilute expression of the black gene. 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. Only Russian Blues and the French Chartreux have this type of coat, which is described as thick and wonderfully soft to the touch. 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 faults 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), nor the Chartreux or Korat which are two other naturally occurring breeds of blue cats, although they have similar traits.

The Russian Blue is known for being a very intelligent and active animal. They have been known to open doors/windows, play fetch, and are sensitive to basic human emotions. They enjoy playing with a variety of toys and develop extremely loyal bonds to their loved ones. The Russian Blue is also known for getting along very well with other pets and children in a household. They are known also for being quiet and clean animals that are normally reserved around strangers, unless they are brought up in a very active household.
