Korat Mix: Is My Grey Cat Part Korat?
The honest identification guide: the heart-shaped head, the silver-tipped single coat, the green eyes with amber tolerated, and why no DNA test can settle it.

Here is the honest arithmetic before the checklist: the Korat is one of the fancy's rarest breeds, with a handful of breeders per continent and closed studbooks, so the odds that a shelter grey carries Korat ancestry are low everywhere and lowest outside Thailand. But grey cats deserve their question answered properly, so here is what actually distinguishes a Korat, what does not, and why no lab can settle it for you.
The marker that counts: the heart-shaped head
Every Korat registry, and 's own comparison article, describes the same first trait: the heart-shaped head, the broad curve of the skull tapering to the chin, read best face-on. It is the single most consistently documented identification mark in this breed's file, and no other grey breed's standard describes anything like it. If your cat's face does not read as a heart, the Korat question is mostly answered.
The coat: one color, one layer, silver at the tips
The Korat comes in exactly one color at every registry on earth: blue (grey) with silver tipping, each hair pale at the root and silvered at the end, giving the sheen the Thais named the breed's fortune for. The coat is SINGLE and close-lying, no downy undercoat: stroke against the grain and it falls flat, where a Russian Blue's double plush springs back. A grey cat with tabby ghost-marks, white spots, or a woolly double coat is telling you its answer.
The eyes: green, with the amber allowance
Adult Korats carry green eyes, and this breed's own standards, unusually, tolerate an amber cast, a leniency the Russian Blue does not get. Two honest caveats: kittens' eyes start amber and settle toward green over a couple of years, so a young grey cat's eye color is not yet evidence either way; and plenty of non-Korat greys have greenish eyes, so eyes support a case, never make one.
Why no test can settle it
No laboratory offers a DNA test for Korat ancestry: breed-mix panels estimate against reference populations and a breed this rare and closed is exactly where they blur. Identification here is visual and probabilistic, never genetic. If your grey cat has the heart face, the flat single coat with silver tips and settled green eyes, you may well have the world's luckiest look-alike or a genuine mix; either way you have a cat Thai tradition calls a good-fortune color, and our comparison page will help you rule the other greys in or out.
The three-check card
- Face-on: does the head read as a heart, broad skull curving to the chin?
- Coat: blue with silver tips, SINGLE layer that lies flat stroked against the grain?
- Eyes (adult): green, possibly with an amber cast?

Frequently asked questions
How can I tell if my cat is part Korat?
Face-on first: the heart-shaped head is the breed's most documented marker. Then the coat, blue with silver tipping, single-layered and close-lying, and settled green eyes (amber cast tolerated). All three together make a plausible case; none alone does.
Is there a DNA test for Korat mix?
No. No lab markets a Korat-ancestry test, and consumer breed panels are least reliable exactly on rare, closed breeds like this one. The identification is visual.
My grey cat has yellow eyes. Could it be a Korat?
If the cat is young, wait: Korat eyes settle from amber toward green over about two years. In an adult, gold-to-copper eyes point elsewhere in the grey family, toward the Chartreux or British Blue look.
Are Korat mixes common?
No: with closed studbooks and a handful of breeders per continent, Korat ancestry is genuinely scarce outside Thailand. Most silvery greys are wonderful domestic shorthairs wearing the same fortunate color.
What does a real Korat cost, if mine is not one?
The market barely publishes prices; our price page carries the honest, mostly-silent four-market picture and the DNA paperwork a real Korat comes with.

This is information, not veterinary advice, and it cannot tell you what is wrong with your cat. Our rule is a simple one: if something is wrong with your cat, call your vet, and call an emergency clinic if it is out of hours. Nothing you read here is a reason to wait.
Medical information applies to every reader. Prices, legal duties and common practice do not: unless stated otherwise, they are given for the United States, and they differ in the UK, Canada and Australia, and often between states or provinces. Check with your own vet and your own local authority.
