The Oriental Cat - a Siamese in designer Genes! The Oriental breed is derived from the Siamese, and has similar build and temperament, but comes in a much wider range of colors (the largest colour group of any pedigree breed), as well as both long and short hair. The Oriental is long, lean and muscular, with large triangular ears and a triangular shaped face. They have green eyes and a Siamese voice - and they like to use it!
