Decision first

Is a Korat right for you?

Start with fit before history or trivia. These are ownership signals, not guarantees about any individual cat.

Best suited for

  • Households with children.
  • Homes with other compatible pets.
  • Apartment homes with a consistent routine.
  • Owners seeking a manageable indoor routine with predictable care.

Think carefully if

  • You need a cat with almost no daily routine.
  • You cannot keep up with grooming and preventive care.
  • The cat will spend most days without interaction or enrichment.

Conditional fit

Apartment fit depends on vertical space, litter setup, play, enrichment, and noise tolerance.

Daily reality

Daily life

Korat temperament and behavior

The Korat is a silver-blue cat from Thailand and one of the oldest naturally occurring breeds in the world — but the single most important thing to know before you buy one is not its temperament or its looks, it is two recessive genes. Korats can carry GM1 and GM2 gangliosidosis, fatal neurological storage diseases. Both are now DNA-testable, which means a responsible Korat purchase is no longer a gamble: it is a question you ask the breeder and a piece of paper you insist on seeing. Lead with that, because no amount of charm offsets a kitten that will not live past its first birthday. Physically the Korat is unmistakable: a single silver-tipped blue coat that has no undercoat (so very low shedding), a heart-shaped face viewed from the front, a gentle downward curve to the nose in profile, and oversized luminous green eyes that often do not finish turning from amber to green until the cat is two to four years old. The body is muscular and surprisingly heavy for its size — three to five kilograms of dense, compact cat. Temperament is where buyers need realistic expectations. Korats bond intensely, usually to one or two people, and want to be the only pet. They are dog-friendly with slow introductions but are often territorial and bossy toward other cats, so a Korat is frequently happiest as a solo animal or the established resident, not the newcomer. They are highly intelligent, trainable, expressive, and sensitive to loud noise and chaos. Who the Korat is right for: a household that wants a deeply bonded, low-shedding, interactive companion and is willing to be a one-cat (or Korat-first) home. Who it is wrong for: anyone buying on impulse from an untested line, or anyone wanting a hands-off cat that tolerates a rotating cast of other pets.

Care essentials

How to care for a Korat

What looking after one actually involves: play, grooming, food, litter, and routine health.

ExerciseAs needed
  • Moderately active breed that enjoys regular play sessions and exploration. Provide toys and occasional interactive games.
GroomingAs needed
  • Low-maintenance coat requiring weekly brushing. Occasional bathing as needed.
NutritionAs needed
  • Feed a high-quality cat food appropriate for their age and activity level. Maintain fresh water at all times. Monitor weight to prevent obesity.
SocializationAs needed
  • Highly social breed that thrives on companionship. Does not do well left alone for extended periods. Consider a companion pet.
Veterinary CareAs needed
  • Annual wellness exams, vaccinations, dental checkups, and parasite prevention. Spay/neuter recommended if not breeding.

Care calendar

Daily

  • Meals, water, litter check, play, interaction, and a quick behavior check.

Weekly

  • Grooming, nails, teeth, eyes, ears, litter pattern, and body-condition review.

Annually

  • Veterinary exam, vaccination review, and preventive-care planning.

Health planning

Korat health risks and screening

Every cat breed has individual health variation. Use this profile for planning and discuss medical decisions with a veterinarian.

GM1 gangliosidosis — an inherited, fatal lysosomal storage disease caused by a recessive mutation in the GLB1 gene. Affected kittens show progressive neurological decline (tremors, ataxia, dysmetria) starting around 3 months and reach terminal stage by 9-10 months. DNA-testable; CFA and TICA recommend testing all breeding stock. A kitten from two DNA-clear parents cannot be affected.
GM2 gangliosidosis — a second, separate fatal storage disease caused by a recessive mutation in the HEXB gene. Onset is even earlier (as young as 4 weeks) and progression faster, with death typically before 8 months. Also DNA-testable and the reason a written parental clearance is non-negotiable before purchase.
Diabetes mellitus — like most domestic cats, an overweight Korat is at elevated risk for feline diabetes; lean body condition is the main controllable lever, since the dense build of this breed hides excess weight.
Dental and periodontal disease — common in shorthaired cats generally; the Korat's long lifespan means untreated tartar progresses to painful tooth resorption and extractions if home brushing and cleanings are skipped.
Stress-linked lower urinary tract signs (FIC) — this sensitive, strongly bonded breed reacts to household upheaval, isolation, or cat-to-cat conflict with cystitis-type straining and inappropriate urination; environment management is preventive medicine here.

Responsible ownership

Finding a Korat responsibly

A responsible path can be a documented breeder or a good rescue match. The important part is transparency and support.

Reputable breeder

  • Ask for documented health screening relevant to the breed.
  • Meet the breeder, review kitten and parent-cat history, and ask how kittens are socialized.

Rescue or adoption

  • Check breed-specific cat rescue groups and reputable shelters.
  • Ask about temperament, medical history, foster notes, and support after adoption.
  • Match the individual cat's age, energy, litter habits, and behavior history to your household.

Warning signs

  • No health documentation.
  • Pressure to buy immediately.
  • No questions about your home or experience.
  • Unclear return policy or unwillingness to provide references.

Original purpose

Korat history

History is useful when it explains today's behavior, coat, exercise needs, and training style.

Read the breed history

The Korat — called Si-Sawat in Thailand — is a natural breed, not a human-engineered one, and one of the oldest documented cats in the world. It appears in the Tamra Maew (the 'Cat-Book Poems' of Thailand, dated to the Ayutthaya period centuries ago), where the silver-blue cat is described as a living symbol of good fortune, traditionally given in pairs to brides and dignitaries rather than sold. Because it bred true on its home soil for centuries with no outcrossing, the Korat is genetically stable and consistent in type — the same cat described in the old manuscripts is the cat you can buy today. The first documented Korats reached the United States in 1959, and the breed was accepted for championship competition by the Cat Fanciers' Association in 1966. That long closed gene pool is a double edge: it preserves a remarkably uniform, healthy natural breed, but it also concentrated the recessive GM1 and GM2 gangliosidosis mutations, which is why DNA testing — not folklore about good luck — is the modern responsible breeder's first duty.

Korat FAQs

How long do Korat cats live?

A healthy Korat from DNA-tested lines typically lives 10 to 15 years, and many reach the upper end because the breed is genetically stable with no extreme conformation. The brutal exception is gangliosidosis: a kitten affected with GM1 rarely survives past 10 months and one with GM2 often dies before 8 months. Lifespan in this breed is decided almost entirely by whether the kitten came from GM1/GM2-clear parents, which is why the test paperwork matters more than anything else you can check.

What is gangliosidosis and how do I avoid it in a Korat?

Gangliosidosis is a group of inherited lysosomal storage diseases — GM1 (GLB1 gene) and GM2 (HEXB gene) — that cause fatal, progressive neurological decline in affected Korat kittens. Both are recessive, so a cat needs two copies to be affected. You avoid it completely by buying only from a breeder who provides written DNA clearance on both parents: a kitten from two clear (or clear-by-parentage) cats has zero chance of being affected. CFA and TICA both recommend testing all breeding stock.

Are Korat cats good with other pets?

Mixed, and buyers should be honest with themselves about it. Korats are notably dog-friendly with slow, positive introductions, but they are often territorial and bossy toward other cats and tend to want to be the only or dominant pet. A Korat usually does best as a solo cat or the established resident, not as a newcomer added to an existing cat household. If you want a multi-cat home, this is a real trade-off to weigh before buying, not after.

How much grooming does a Korat need?

Very little. The Korat has a single silver-blue coat with no undercoat, so a five-minute weekly brush or a damp-hand smoothing is enough; shedding and hairballs are minimal and mats are rare. The real grooming budget goes to the basics shared by all shorthaired cats: nail trims every two to three weeks, weekly ear checks, and tooth brushing several times a week to prevent the dental disease that otherwise costs hundreds in extractions later in this long-lived breed.

Are Korat cats good for apartments and families?

Yes to apartments — they are compact, low-shedding, and bond hard to people over territory, so they adapt well to smaller spaces with 15-25 minutes of daily interactive play. With families, they are good with respectful children but are sensitive to loud noise, sudden movement, and chaos, so a calm household suits them better than a frantic one. They also strongly prefer not to be left alone for long stretches, which is worth weighing if everyone is out all day.

How much does a Korat cat cost?

Expect roughly $600 to $1,200 for a pet-quality Korat kitten and more for show lines from a registered breeder, with price varying by region and rarity since the breed is uncommon. The cost that actually matters is hidden: a gangliosidosis-affected kitten incurs heartbreak plus diagnostics and supportive care, and the cat will not survive its first year. Paying a fair price for a kitten with written GM1/GM2-clear parentage is the single cheapest insurance in this entire breed — never economize by skipping that paperwork.
