Addictional informatio n (Wiki): The Siberian is a domestic cat breed from Russia. The cat, that has similarities with breeds Maine Coon and Norwegian Forest Cat, is a natural breed and the national cat of Russia.

Known to be an exceptionally agile jumper, the Siberian is a strong and powerfully built cat, with strong hindquarters and large, well rounded paws. Their barrel chests and medium sized ears, broad foreheads, and stockier builds.

Siberian cats tend to come into reproductive readiness earlier than other breeds, sometimes as young as five months. It is thought that this is related to the breed's closeness to its natural wild state. Feral cats have difficult lives, often dying young. Therefore, it is a genetic advantage to achieve reproductive ability early and to have large litters. On average, a Siberian litter consists of five to six kittens, as compared to the average litter of three to four kittens in breeds who have been registred as pedigreed cats for many decades. Occasionally, Siberian litters consist of as few as one and as many as nine kittens.
