Oriental cats are derived from the Siamese breed. The ideal cat is svelte, elegant, with long tapering lines, supple and well muscled. The expression should be one of alertness and intelligence. The body, legs, feet, head and tail are all in proportion, giving the whole a well-balanced appearance.
All colours/patterns of Orientals are comparatively darker in colour than their Siamese counterparts, due to the removal of the Siamese ?pointing? gene, which makes the cat self-coloured, and of a darker shade, e.g. Sealpoint Siamese with the ?pointing? gene removed becomes an Ebony/Black.
