Siberian is a centuries-old domestic cat landrace in Russia that has only recently been recognized as a formal breed. 

In addition, the Siberian is a forest cat native to snowy Russia, where its luxurious triple coat protected it from the elements. Siberian cats are very friendly and enjoy being close to their owners. 

Children, dogs, and other animals keep them company. They are fearless and easygoing, and their natural calm and contentment are not disturbed.
