The Ussuri is a rare natural breed of cat that originates from the region of the Amur River Russia. It is reputed to be derived from natural hybrids with small wild cats known as Amur Forest Cats and Amur Leopard Cats (Asian Leopard cat subspecies the same species used in the Bengal cat breed). Semi-wild Ussuris then hybridised naturally with Siberians and European-Domestic Shorthairs. This hybrid origin is based on conjecture and their appearance.
