An early breed of short-haired cat that has enjoyed many names: Blue, Russian, Multese, Multese Blue, Archangel Blue, Chartreuse Blue, Foreign Blue, American Blue, Russi-American Blue, Spanish Blue, Blue Russia and Russian Shorthair. The official title of Russian Blue was finally agreed in the 1940s.
Russian Blue is originally a robust cat with a strong build and rather average proportions, but more recently modified by the introduction of Siamese genes, making it more elongated and angular. Its diagnostic feature is its lustrous, plush, dense, but t of silvery-gray fur. It has a characteristic wedge-shaped head.
It is characterized as affectionate, shy, pensive, intelligent, tranquil, timid, reserved, serene, placid, hardy, obliging, independent, unintrusive, quick-witted, acrobatic, elegant, resourceful, sensitive, temperamental, quiet and loyal.
Recently there have been two new additions to this breed: the Russian White and the Russian Black. Both new breeds are the same as the Russian Blue but of a different color.
