The Siberian is a natural breed first imported from Leningrad Russia on June 28, 1990. They were recorded as participants in the first cat show in England in the 1700's, and have been judged to Grand International Championship overseas prior to their export. Old Soviet law discouraged pet ownership due to the housing and food shortages and war depleted representatives of various purebreds. It was only in 1987 that clubs (recognized as individual registries there) began to keep official records in an attempt to retrieve what had been proscribed or lost. Russian registries provide pedigrees which have the proper seal and signatures to be genuine. Owners are recorded.

This intelligent, energetic and powerful breed is large with a barrel-shaped torso, heavy boning and lynx tips (not to be construed as a pointed ear). They mature in five years. These self-grooming long hair cats take minimal care and the medium long to long coat is most spectacular in winter. The Siberian has a thick triple coat with a full ruff that gets much thicker in the winter months, probably a genetic adaptation trait that helped it deal with harsh Siberian winters. Siberian cats are also popular pets because of their hypoallergenic fur, since they are unique in that they do not have the cat allergen FEL D-1 in their saliva and do not produce dander on their fur. Persons who wanted a pet cat but couldn't because of allergy related problems, now have this option.

Numerous books claim that it was the Siberian mating with the European Wild Cat which led to the development of all the subsequent long-haired breeds in the world. Geneticists believe that the Siberian was the first long-haired as 64% of all long-hair genes center around Leningrad.

The Maine Coon, Norwegian Forest Cat and Siberian have enough similarities and differences, with enough to be historically related and tales of their heritage being from the same general geography, even by geometric shape.

The Maine Coon being composed of rectangles with the longer body, legs and tail, elongated head and tall ears. The Norwegian Forest Cat being composed of triangles with the triangular head, slanted eyes and pointed ears. The Siberian virtually becomes circles with the rounded head, eyes and ears, shorter tail and barrel-shaped body.
