The Oriental Shorthair is a self-coloured (non-pointed) member of the Siamese Family. They can be found in solid colors (white, red, cream, ebony, blue, chestnut, lavender, cinnamon, or fawn), smoke (white undercoat to any of the above except white), shaded (only the hair tips colored), parti-color (red or cream splashes on any of the above), tabby (mackerel/striped, ticked, spotted, and blotched/classic), and bi-colored (any of the above, with white). In total, there are over 300 color and pattern combinations possible. Though in CFA, pointed cats from Oriental Shorthair parents are considered AOV (Any Other Variety), in TICA, as well as in the majority of worldwide Cat Associations, these cats are considered to be, and compete as, Siamese.
Oriental Shorthairs have expressive, almond-shaped eyes, a wedge-shaped head with large ears that fit in the wedge of the head. Their bodies are very elegant yet muscular. When seeing an Oriental Shorthair, one would never guess them to be as solid as they are.
The longhaired version of the Oriental Shorthair, Oriental Longhair, simply carries a pair of the recessive long hair gene.
