Introduction:
The Russian blue is a cat breed that comes in the different colours varying from the silver to slate grey. They develop the close bond with their owners. Dense coat which has been the Hallmark of Russian breed. The dense coat stands out from body and they are also consider to be hypoallergenic.
Origin:
This is the natural occurring breed that may have originated in the port Arkhangelsk in Russia. They are sometime called the archangel Blues. It is believed that sailors took Russian Blues from the Archangel Isles to Great Britain and Northern Europe in the 1860s. The first recorded appearance outside of Russia was in 1875 at The Crystal Palace in England as the Archangel Cat. The Russian Blue competed in a class including all other blue cats until 1912, when it was given its own class. The breed was developed mainly in England and Scandinavia until after World War II.
Right after the war a lack of numbers of Russian Blues led to cross breeding with the Siamese. Although Russian Blues were in the United States before the war it was not until the post-war period that American breeders created the modern Russian Blue that is seen in the United States today.
American breeders combined the bloodlines of both the Scandinavian and British Russian Blues. The Siamese traits have now largely been bred out. The short hair and slate-gray/blue color is often seen in mixed-breed cats which can affect breeders and showers due to mislabeling a cat as a Russian Blue.
Russian blue cat has the short hair and has the green eyes.  They have been use limited basis to create other breeds such as the Havana brown and Nebelung.
Russian white and Russian black were created from the cross breeding with domestic white cat which were imported from Russia. 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. However the Cat Fanciers Association.

Physical characteristics:
The Russian Blue has bright green eyes and 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 and each parent will have a set of two recessive genes two non-CPC Russian Blues will always produce a blue cat. Due to the breeding with Siamese after World War II there are color point 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.
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.

Growth and maturity:
Russian Blues have a life expectancy of around 10 to 20 years but some have even lived up to a maximum of 25 years and have few health problems as they tend to have little to no genetic problems and are not prone to illness. They are small to moderate sized cats with an average weight of 2.27 to 5.45 kg. Males will typically be larger than females. Their gestation period is approximately 64 days.
