Temperament
The Korat is a cat that considers itself head of the household. It is deeply attached to its people and its home, likes to be pampered and kept close, and is remarkably bright. It can open a cabinet with its paw, solves puzzle toys and quickly learns what words mean. It communicates with a variety of sounds and expressive facial expressions. It enjoys playing but is not hyperactive. It can be wary of strangers, which may come across as aloofness. It likes quiet and predictability, and a loud, busy household wears it out. The most important practical trait: a Korat often wants to be the only pet in the home. VCA rates it low for compatibility with dogs and children, and it can be territorial and bossy toward other cats. Purina recommends it for experienced owners rather than families.

Who is the Korat for?
The Korat suits experienced owners, singles and couples in a quiet apartment who want one very devoted cat and spend a lot of time at home. It is not a good choice for a family with young children, a home with a dog or someone planning to keep several cats. People who work long hours away from home would do better with a more independent breed.

- exceptionally intelligent
- barely sheds

Care and exercise
Grooming a Korat is minimal: the short, close-lying coat has no undercoat, so a weekly once-over with a soft brush or rubber grooming glove is enough. The cat barely sheds. Its mental needs matter much more. A Korat needs a calm home, daily play and challenges to occupy its clever mind: puzzle toys, learning tricks for treats, treats hidden around the home. The breed matures slowly, reaching full maturity at around five years old, and the eye color changes from amber to green between the ages of two and four. Because Korats can be possessive toward other animals, think carefully before bringing home a second cat and introduce it very slowly. Food portions are best worked out with your vet.

The Korat is considered a generally healthy breed. The best-documented inherited diseases are GM1 and GM2 gangliosidosis, storage diseases in which abnormal substances build up in nerve cells, leading to progressive neurological problems. Purina stresses that they are rare in the breed, and an available DNA test lets breeders avoid mating carriers. Atherosclerosis, a disease rarely seen in cats, has also been described in some Korats. When buying a kitten, ask for the parents’ test results and the vaccination record. Purina gives a lifespan of 10–15 years, VCA 9–15 years.

Breed history
The Korat is one of the oldest cat breeds. The Thai “Tamra Maew” (“Cat Book Poems”), written during the Ayutthaya period (1350–1767), depicts it among 17 cats that bring good luck. The name comes from the province of Nakhon Ratchasima (Korat), and the breed itself from the area around Phimai. In Thailand, Korats were traditionally given as gifts to newlyweds, and there they are called si sawat. In the late 19th century, they appeared in Britain as “blue Siamese.” The breed’s real history in the West began in 1959, when Jean Johnson brought two Korats to the US. Later, Daphne Negus imported more cats from Thailand, widening the gene pool. The CFA granted the breed championship status in 1966.

Frequently asked questions
Do Korat cats get along with other cats?
It varies. Many Korats prefer to be the only pet in the home and can be territorial or bossy toward other cats, and they don’t get along well with dogs. If you want a second cat, introduce it very slowly and be prepared for the Korat not to accept it.
How big do Korat cats get?
The Korat is small: Purina gives 2.7–4.5 kg. Mature males can be heavier and, according to the CFA, may exceed 4.5 kg, while females are smaller. The Korat has a compact, muscular build, so it feels heavier in your arms than it looks.
What is the difference between a Korat and a Russian Blue?
Both cats are blue with green eyes, but the Korat has a single, close-lying coat without undercoat and with silver-tipped hairs, while the Russian Blue has a dense, plush double coat. The Korat is also usually more possessive toward other animals.
How long does a Korat live?
The typical lifespan of the Korat is 10–15 years. Genetics, weight, exercise and regular preventive vet care all make a difference.
