Thai Cat: Temperament, Size, Care & History

The Thai cat is the Siamese cat as Europe saw it at the end of the 19th century: elegant but moderate, with a light body, dark points on the face, ears, legs, and tail, and bright blue eyes. While the modern Siamese became increasingly slender and angular, some breeders preserved the old style, which is recognized today as a distinct breed—the Thai. In Thailand, its ancestor is called the Wichien Maat, or "moon diamond." In our cat breeds directory, you will find this breed's history, appearance, and personality.

The Thai Cat: The Old-Style Siamese That Remained Unchanged

Cats brought from Siam (modern-day Thailand) to the West in the 19th and early 20th centuries had a more moderate build than today's Siamese cats. After World War II, increasingly long, slender, fine-boned cats with distinct wedge-shaped heads began to dominate cat shows, and this modern type became the standard Siamese look. In the 1980s, clubs emerged in North America and Europe dedicated to preserving the early 20th-century Siamese type, which still lives in Thailand.

The WCF recognized the old style as a distinct Thai cat breed with full championship status in 1990. In Great Britain and North America, these cats were long registered as Siamese; in 1999, the US club PREOSSIA coined the name "Old-Style Siamese," and in 2000, the Old-style Siamese Club was founded in Britain. TICA declined to use this name, so breeders adopted the European name "Thai," and in January 2010, TICA granted the breed championship status. FIFe gave the Thai preliminary recognition in 2015 and full recognition in 2017. Since 2001, cats have been additionally imported directly from Thailand to preserve the traits of the native cats.

Appearance: The Moderate Siamese Type

Thai and Siamese cats share the same dark point gene and the same personality—they differ only in body and head type. The Thai cat is of medium size and bone structure, muscular, and heavier than it appears. Its body is longer than that of an average domestic cat, but significantly less so than the modern Siamese or Oriental. The head is a modified wedge, longer than it is wide, with a long flat forehead and a nose that has at most a slight dip at eye level. The ears are fairly large, and the eyes are oval, fairly large, and deep blue.

The coat is short, close-lying, and single-layered, lacking the longhair gene. Under the FIFe standard, the recognized natural point colors are seal, blue, chocolate, lilac, red, and tortoiseshell, as well as their tabby (lynx) variants. Like other colorpoint cats, Thai kittens are born light, and their points darken over several weeks.

Personality: Affectionate, Vocal, and Always Involved

Breed standards describe Thai cats as affectionate and very deeply attached to their families. They are highly vocal, though perhaps not quite as loud as some other breeds, and they clearly express their feelings when they think it is necessary. A Thai cat always participates in its owner's daily routine, loves to be involved, and enjoys learning tricks. They are incredibly intelligent and sensitive, getting along wonderfully with children and other pets. Like Siamese cats, they dislike being left alone for long periods, so if you are away from home often, it is worth considering getting them a feline companion.

Health: The Siamese Group Heritage

Few diseases are described as specific to the Thai cat breed, but because it shares the same roots as the Siamese, it is worth being aware of conditions common to the Siamese group. These include progressive retinal atrophy (PRA), which can be identified through a genetic test, and amyloidosis. The issue of genetic diversity is also important, which is why breeding programs are supplemented with cats from Thailand. Like other active cats, they require regular veterinary check-ups and dental care.

Care: Simple Grooming, High Attention Needs

• Coat. The short, single coat only needs to be wiped with a damp hand or a rubber brush a few times a month.
• Activity. Trick training, puzzle toys, wand toys, and tall cat trees are essential.
• Warmth. With very little undercoat, this cat loves warm spots.
• Companionship. A second cat is highly recommended if the house is empty for long hours.

Daily Life with a Vocal and Social Cat

The Thai cat wants to be involved in everything you do: following you to the kitchen, checking what is happening on your desk, and loudly announcing when they need something. They are best suited for homes where someone is frequently around, or a family that has two cats. Set aside time every day for play and trick training—this intelligent cat quickly learns to come when called or give a paw. The short, single coat offers little protection from the cold, so in winter, they will seek out the warmest spot, whether that is a radiator bed or their owner's lap.

How to Choose a Thai Kitten

When looking for a reputable breeder, ask which registry the kitten is enrolled with, as registry rules for Thai cats differ (in the US, the breed is registered by TICA). Always meet the parents to evaluate their type and temperament, and ask to see health test results, particularly for PRA. Because kittens are born light, their final color is best predicted by looking at their parents' pedigrees. Reputable breeders typically do not let kittens go to their new homes before 12 to 14 weeks of age. We discuss standard US practices like microchipping and registration in our cat breeds directory introduction.
