We breed both Siamese and Oriental Cats.
The Siamese and Oriental Cats are very similar in body shape, activity and personality. They are very intelligent and people oriented animals who bond closely with their owners.

Siamese Cats:

The most striking characteristic of the Siamese cat is its "points," which are darker color patterns on the ears, face (mask), tail, legs, and feet. Colors allowed in the CFA Breed Standard are seal, chocolate, blue, and lilac.

Orientals Cats:

The colorful relatives of the Siamese, you can think of Orientals as Siamese in designer clothes . 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, there are over 300 color and pattern combinations possible. More info HERE.
