According to the CFA breed profile, "Orientals represent a diverse group of cats that have their foundation in the Siamese breed."[2] The Siamese, in both pointed and solid colors, was imported to the UK from Siam (today, Thailand) in the later half of the 1800s, and from there spread widely, becoming one of the most popular breeds. The gene that causes the color to be restricted to the points is a recessive gene; therefore, the general population of the cats of Siam were largely self-colored (solid). When the cats from Siam were bred, the pointed cats were eventually registered as Siamese, while the others were referred to as "non-blue eyed Siamese" or "foreign shorthair". Other breeds that were developed from the landrace cats of Thailand include the Havana Brown (which some breed registries classify as simply an Oriental Shorthair variant) and the Korat.
