The Siberian is one of the largest breeds of domestic cat. Siberian males range between 17 and 26 pounds and the females range between 13 and 17 pounds. As befits a cat that has survived the harsh climate of Siberia, the Siberian possesses a long, thick coat with a full ruff and a tight undercoat that becomes thicker in cold weather. The coat's oily guard hairs give the coat its classic water resistance. All colors and patterns are accepted except pointed colors, although pointed Siberians exist in Russia and are called Nevsky Masquerades.
The Siberian is a domestic cat breed that has been present in Russia for centuries. A longer name of the breed is Siberian Forest Cat, but it is usually referred to as the Siberian or the Siberian cat. Another name for it is the Moscow Semi-longhair. The cat is an ancient breed that is now believed to be ancestral to all modern long-haired cats. The cat has similarities with the Norwegian Forest Cat, to which it is likely closely related. It is a natural breed of Siberia and the national cat of Russia.
Siberians are affectionate cats with a huge dose of personality and playfulness. They love to be handled, and owners note that Siberians have a fascination with water, often dropping toys into their water dishes or investigating bathtubs before they're dry. Siberians are very intelligent, with the ability to problem-solve to get what they want. Despite their size, they are very agile and are excellent jumpers, able to leap tall bookcases in a single bound.
Hypoallergenic qualities of the Siberian coat have been noted and commented on for almost ten years. Pet owners claim that Siberians can be safe for many allergy sufferers. Since spayed females of all feline breeds produce lower levels of Fel d1, breeders often suggest that allergic families adopt female cats. Allergy sufferers are advised to check their reactivity directly with the kitten they plan to adopt. Scientists have proven that the breed produces less Fel d1, the primary allergen present on cats.
