About the Korat

The Korat is a rare Thai natural breed recognized in Ireland through the ICA and TICA, whose silver-blue coat finds an unexpected resonance in Ireland's silver Claddagh heritage and the mist-laden Atlantic landscape.

The Korat is one of the oldest natural cat breeds, originating in the Korat province of north-eastern Thailand. It is a small to medium cat with a single, close-lying coat that is blue tipped with silver. The ancient Thai manuscript known as the Tamra Maew, or Cat-Book Poems, describes this cat as cloud-coloured with eyes like dewdrops. Under Ireland's famously grey Atlantic skies, that description takes on an almost native resonance: the Korat's mist-and-silver colouring feels genuinely at home in a country built on rain and cloud.

In its homeland the Korat is called Si-Sawat and is honoured as a living symbol of good fortune, traditionally given as wedding-gift pairs to bring prosperity. That tradition of silver-and-good-luck carries its own Irish parallel: the Claddagh ring, Celtic silver knotwork, the silvered grey of a Connemara morning all share that palette. The Korat's coat connects visually to all of it.

In Ireland the Korat is registered through TICA-affiliated bodies and the Irish Cat Association (ICA), which is affiliated with FIFe. The breed is rare across the island, and those who seek a kitten generally import from the Netherlands or Scandinavia, where the strongest European Korat breeding communities are established.

Who the Korat suits

The Korat suits Irish households that want a rare, deeply loyal cat and appreciate a breed with centuries of living tradition behind it. Its sensitivity to noise and reserved nature with strangers fits well in quieter rural or suburban Irish domestic settings. The breed does best with owners who are home often and can give it consistent company. Those who enjoy the slower, more deliberate route to rare breeds, such as registering with the ICA and reaching out to Dutch or Scandinavian breeders, often find the wait worthwhile.

History of the Korat

The Korat is a natural Thai breed documented for centuries as the Si-Sawat good-luck cat, brought to the West in the mid-twentieth century and developed from a small number of imported cats.

The Korat takes its name from the Korat province (Nakhon Ratchasima) in the north-east of Thailand, where it has existed as a natural breed for centuries. In Thailand it is known as the Si-Sawat, a name that refers to its silver-blue colour and carries a sense of good fortune and prosperity.

The breed appears in a Thai manuscript known as the Tamra Maew, or Cat-Book Poems, a collection of verse and illustration describing native cats. The Si-Sawat is among the cats depicted there, which places written record of the type well before its arrival in the West. Korats were given in pairs to mark weddings and to wish good luck, and they were kept and bred close to their original population.

Korats reached the United States in 1959, when a breeding pair was imported from Thailand. American breeders built their lines from this and later imports, keeping the population close to its Thai roots rather than crossing widely with other breeds. The Korat Cat Fanciers Association formed in the years that followed to record pedigrees and promote the breed.

Major registries recognised the Korat through the 1960s, and breeders have continued to import cats directly from Thailand to maintain genetic diversity. In Ireland the breed is registered through TICA-affiliated bodies and the Irish Cat Association (ICA). It remains relatively uncommon, and many catteries still trace their cats to documented foundation imports.

Korat appearance

The Korat is a small, muscular cat with a heart-shaped face, large luminous green eyes, and a single silver-tipped blue coat that has no other accepted colour.

The Korat is a compact, semi-cobby cat that carries surprising weight for its size because of dense muscle. The head forms a heart shape when viewed from the front, with a strong jaw and a slight stop on the nose. The ears are large, set high, and rounded at the tips. The eyes are the breed's most striking feature: large, round when open, and a luminous green at maturity. Kittens are often born with amber or yellow-green eyes that deepen to full green over the first two to four years.

Coat and colours

The Korat has one accepted colour: a solid blue coat in which each hair is tipped with silver. The silver tipping catches the light and produces a halo or sheen, most visible on a cat in good condition. The coat is short, fine, and lies flat against the body, with no woolly undercoat. Because there is only one coat and no undercoat, the Korat sheds less than many cats and needs little grooming. There are no markings, patches, or alternative colours in the breed standard.

Korat temperament

The Korat is affectionate, devoted, and gentle, forming deep bonds with its people while staying alert and sensitive to noise and change.

The Korat is a people-focused cat that attaches closely to its household, and it often picks out one or two favourite people. It likes to stay near them, sit on a lap, and join in with whatever they are doing. The breed communicates with a soft, expressive voice rather than constant loud demands, and it reads its owner's moods with noticeable attention.

With family, the Korat is warm and loyal. With strangers it tends to be reserved at first, watching from a distance before it decides to come closer. It is intelligent and curious and learns household routines quickly. The breed can be assertive about wanting company and may dislike being left on its own for long stretches.

Korats are sensitive cats. Sudden noise, rough handling, and frequent disruption unsettle them. They usually get on well with another calm, compatible cat or a respectful dog, though they can be wary of boisterous animals. With gentle older children who handle them quietly, they are affectionate; very young, loud children are a poorer match.

Korat care

The Korat is low-maintenance to groom thanks to its single coat, but it needs steady company, moderate play, and a calm, stable home to stay content.

Grooming

The Korat's single, short coat is easy to maintain and sheds modestly.

  • Brush or hand-stroke once a week to lift loose hair and keep the silver sheen
  • Wipe the coat with a damp hand or chamois between brushings for shine
  • Trim claws every two to three weeks
  • Check and clean the large ears regularly, and brush the teeth to limit dental disease

Exercise

The Korat has moderate energy and enjoys short, regular bouts of play.

  • Offer two or three play sessions a day with wand toys or chase toys
  • Provide a cat tree or shelves for climbing and a high perch for watching
  • Rotate puzzle feeders and small toys to keep an intelligent cat occupied
  • Use interactive play to bond, since this cat prefers playing with its person

Environment

The Korat thrives in a calm, predictable indoor home. Ireland's cool, damp climate causes no particular difficulty: the Korat's single coat is short and close-lying, and the breed adapts well to centrally heated Irish homes. What it cannot manage well is noise and frequent disruption, so a quiet rural cottage suits it as much as a calm city apartment. Keep feeding, play, and rest on a steady routine. If importing from the Netherlands, UK, or Scandinavia, check DAFM health certificate requirements well in advance. Indoor housing protects this rare breed from traffic, outdoor hazards, and disease.

Korat nutrition

The Korat needs a complete, protein-rich cat food fed in measured portions to keep its dense, muscular body in good condition without excess weight.

As an obligate carnivore, the Korat needs a complete and balanced diet built around animal protein. Choose a quality cat food appropriate to the cat's life stage and follow the feeding guide on the label, then adjust to body condition. The Korat is muscular and can carry more weight than its frame suggests, so portion control matters. Fresh water should always be available, and many cats benefit from some wet food to support hydration.

General feeding guide (adjust to the individual cat)
Life stageAmount per dayMeals
Kitten (2 to 12 months)Per label, free-fed or 3 to 4 meals3 to 4
Adult (1 to 7 years)About 50 to 70 g of dry, or equivalent wet2
Senior (7+ years)Adjusted to weight and activity2

Treats and supplements

Keep treats to no more than about ten per cent of daily calories so the main diet stays balanced. A complete commercial food usually needs no added supplements; give any vitamins or joint support only on a vet's advice. Use small, low-calorie treats during training and play to reward the cat without encouraging weight gain.

Korat health

The Korat is generally a healthy, long-lived breed of 12 to 15 years, with a known genetic risk for two related neurological storage disorders that responsible breeders screen for.

The Korat is a robust natural breed and usually lives 12 to 15 years with good care. Its main documented health concern is a pair of inherited neurological conditions, GM1 and GM2 gangliosidosis, which are lysosomal storage disorders seen in the breed. Reliable DNA tests exist for both, and reputable breeders test their breeding cats so affected kittens are not produced. Buying from a breeder who screens for these conditions is the most important health step for the breed.

Conditions noted in the Korat
ConditionSignsNote
GM1 gangliosidosisTremors, weakness, declining coordination in young catsInherited; DNA test available, breeders should screen
GM2 gangliosidosisProgressive neurological decline in early lifeInherited; DNA test available, breeders should screen
Dental diseaseBad breath, drooling, tartar, sore gumsCommon in cats; managed with dental care
ObesityWeight gain, reduced activityManage with measured portions and play

Preventive care

  • Schedule annual veterinary exams, and twice yearly for senior cats
  • Keep core vaccinations and parasite control up to date
  • Maintain dental care with brushing and professional cleaning as advised
  • Feed measured portions and monitor body condition
  • Buy only from breeders who DNA-test for GM1 and GM2 gangliosidosis

Korat training

The Korat is intelligent and eager to please its people, which makes it responsive to gentle, reward-based training for litter habits, handling, and simple tricks.

The Korat is a smart, attentive cat that learns quickly and enjoys interacting with its owner, which gives training a strong foundation. Because the breed is sensitive, it responds far better to patience and rewards than to pressure or scolding. Short, positive sessions hold its interest, and the close bond it forms means it is often motivated by praise and time with its person as much as by food.

Basics

  1. Set up a clean, quiet litter tray early and keep it in a consistent place
  2. Provide a scratching post and reward its use to protect furniture
  3. Get the cat used to gentle handling, carrier, and grooming from kittenhood
  4. Reward calm, wanted behaviour right away with a treat or praise
  5. Teach simple cues such as come or sit in brief sessions, then build from there

Korat breeding

Korat breeding centres on health-tested parents and careful, ethical pairing, since the breed carries inherited gangliosidosis and is uncommon enough to require attention to genetic diversity.

Responsible Korat breeding begins with DNA testing both parents for GM1 and GM2 gangliosidosis so that no affected kittens are produced. The breed is relatively rare, and many lines trace to a small number of foundation imports, so breeders also weigh genetic diversity and sometimes work with cats imported directly from Thailand. Females typically reach sexual maturity within the first year, though responsible breeders wait until a queen is physically mature and health-checked before mating.

Gestation in cats lasts about 63 to 67 days. Korat litters are usually small to moderate in size. Queens generally raise their kittens well, and newborns depend fully on the mother for warmth and milk in the first weeks. Kittens open their eyes within the first two weeks and begin weaning around four to six weeks. Eye colour is amber or yellow-green at first and deepens toward the breed's mature green over the following years.

Kittens should stay with the mother and litter until at least twelve weeks so they are weaned, socialised, vaccinated, and ready for a new home. Early gentle handling helps produce confident adults that match the breed's affectionate reputation.

Korat frequently asked questions

Common questions about the Korat cover its size, temperament, care needs, lifespan, suitability, and how readily the breed can be found.

Where can I find a Korat breeder in Ireland?

The Korat is rare on the island of Ireland. Contact the Irish Cat Association (ICA) or TICA registries to locate registered breeders. Most Irish owners import from the Netherlands or Scandinavia, where the strongest European Korat breeding communities operate; DAFM health documentation is required for import.

Why does the Korat's coat resonate with Irish aesthetics?

The Tamra Maew describes the Korat as cloud-coloured with eyes like dewdrops, and Ireland's own visual culture, from Claddagh silver jewellery to Celtic knotwork to the grey Atlantic coastline, shares that same silver-blue palette. The Korat is one of the rare cats whose appearance feels genuinely at home in Ireland's light.

Is the Korat suited to Ireland's climate?

Yes. As an indoor cat the Korat manages well in Ireland's cool, damp climate. Its single coat means it is not built for cold outdoor conditions, but in a centrally heated Irish home it is comfortable year-round. The breed's quiet, reserved temperament suits quieter rural and suburban Irish settings well.

How big does a Korat get?

The Korat is a small to medium cat, usually weighing about 2.7 to 4.5 kg. It is muscular and dense, so it often feels heavier than it looks.

How long do Korats live?

With good care a Korat typically lives 12 to 15 years. Buying from a breeder who DNA-tests for GM1 and GM2 gangliosidosis supports a healthy, long life.

Is the Korat good for families?

Yes, for the right household. It suits attentive adults, older children who handle cats gently, and homes with a calm routine. It is less suited to very loud, busy environments or long daily absences.

Does the Korat shed a lot?

No. The Korat's single coat with no woolly undercoat means it sheds far less than most cats, which makes it low-maintenance to groom in any Irish home.
