The Siberian (Forest) Cat is an ancient breed now believed to have been ancestral to all modern longhaired cats including both the Angora and the Persian. The overall impression should be a cat of great strength and size with excellent physical tone. This large and impressive cat has a distinctive semi-long, dense triple coat of sculptured appearance, and a thick, densely covered tail, with no trailing hairs. Tail should have a rounded or blunt tip. This is a cat of circles or roundness, rather than angular features. Males are generally larger than females.
