The Oriental Shorthair is a Siamese cat in over three hundred different outfits

In short: Developed from the Siamese, the Oriental Shorthair shares its sleek, muscular build and inquisitive, vocal personality. While its ancestor is defined by pointed markings and blue eyes, the Oriental offers a vast kaleidoscope of over 300 possible coat colours and patterns, making it a unique masterpiece of selective breeding.

The Oriental Shorthair traces its genetic roots back to landrace cats from Siam, now Thailand. While the Siamese breed became famous for its pointed coat—a trait governed by a recessive gene—the original population in Siam was largely full-coloured. When these cats were imported to the UK in the late 1800s, breeders focused on the pointed variety, often relegating the non-pointed, non-blue-eyed individuals to the sidelines. It was not until the 1950s that Baroness von Ullmann began breeding these solid-coloured, Siamese-type cats, eventually catching the attention of American breeders like Vicky and Peter Markstein in the early 1970s.

Formal recognition followed quickly. After the formation of the Oriental Shorthairs International group in 1973, the breed was presented at the 1976 annual meeting of the Cat Fanciers' Association (CFA). By 1977, the CFA accepted the Oriental Shorthair for championship competition. The UK-based Governing Council of the Cat Fancy (GCCF) followed suit in 1997. Today, the breed is celebrated for its physical consistency—featuring a wedge-shaped head, large ears, and almond-shaped eyes—contrasted against an immense variety of coat aesthetics, including solid, tabby, smoke, shaded, and parti-colour patterns.

Beyond their appearance, these cats are noted for their high energy and social intelligence. Breeders and veterinarians describe them as active, curious, and remarkably vocal, often maintaining a playful, kitten-like disposition well into adulthood. They are athletic jumpers that thrive on human interaction and generally prefer the company of other cats, making them a lively addition to any household. While the CFA and other organizations maintain specific standards for what constitutes an Oriental, the breed remains a testament to the diversity hidden within the Siamese lineage, offering a sophisticated alternative for those who admire the Siamese temperament but desire a broader palette of colours.

The breed's classification can be complex, as different registries have varying rules. For instance, the World Cat Federation (WCF) generally opposes white in its colour requirements, while the CFA classifies certain point-coloured offspring as 'any other variety' or Colourpoints. Despite these regulatory nuances, the Oriental Shorthair stands as a distinct, medium-sized breed, with males typically weighing between 3.5 and 5.5 kilograms and females generally weighing under 3.5 kilograms.
