Oriental Shorthairs are intelligent, social animals who bond very closely to their people. They are inquisitive, friendly, emotional, demanding and often quite vocal. They will depend on and trust you forever if you love and take care of them. Their purr can be extremely loud when happy.
The Oriental Shorthair is a member of the Siamese family. They can be found in solid colors (white, red, chocolate, cream, ebony, blue, 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, over 300 color and pattern combinations are possible.
Oriental Shorthairs, like any of the Siamese type, have almond-shaped eyes and 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.
