If you’ve never lived with a Korat, picture a compact silver-blue cat that follows you room to room and sits on the edge of whatever you’re doing. Talk to it and you’ll get soft little chirps back. That’s the day-to-day. Korats are affectionate to the point of being clingy, they bond hard to one or two people, and they’d rather be in your business than napping alone in another room.
They’re also rare and not cheap. A well-bred Korat from a registered breeder usually runs $1,200 to $2,000, waitlists stretch for months, and there’s one health test you absolutely have to confirm before you pay a deposit. I’ll get to that. First, what this cat is actually like.
About the Korat cat
The Korat is one of the oldest natural cat breeds, originally from the Korat province of Thailand, where it’s long been treated as a good-luck cat and given in pairs to newlyweds. “Natural breed” matters here: nobody engineered the Korat by crossing other cats. It looks the way it does because it bred true in one region for centuries. It arrived in the United States in 1959 and the Cat Fanciers’ Association recognized it in 1966.
What sets it apart visually is the single silver-tipped blue coat and, eventually, those green eyes. The head is heart-shaped from the front. The body is small to medium but solidly muscular, with a quiet, alert elegance to the whole cat. It’s not a flashy show-off breed. It’s a devoted companion that happens to be beautiful.
If you’re weighing the Korat against other talkative, people-first breeds, it sits in a similar temperament neighborhood to the Siamese and the Burmese, just quieter than the former and a touch more reserved with strangers than the latter.
Korat personality and traits
This is the part most people underestimate. Korats are not aloof cats. They’re emotionally involved in your life, and they notice when you’re gone.
Here’s what stands out after you’ve lived with one:
- They pick their people. A Korat usually forms an intense bond with one or two family members and shadows them. Lap time, shoulder time, sitting on the keyboard, all of it.
- They’re soft-spoken. They do talk, but it’s chirps and trills, not the foghorn of a Siamese. You’ll have quiet little back-and-forth conversations.
- They love interactive play well into adulthood. Fishing-pole toys are catnip for a Korat’s brain. Mine would lose its mind over anything with feathers on a string long after most cats mellow out.
- They’re smart and a bit sensitive. Korats learn routines fast and can even be leash-trained. The flip side: they don’t love loud chaos and can get stressed by big disruptions.
- They’re playful but not hyperactive. Moderate energy. They want engagement, not a marathon. A couple of real play sessions a day keeps them happy.
If you want a cat that ignores you and lives its own life, skip the Korat. If you want a small shadow that greets you at the door and sleeps against your legs, this is your breed.
For toys that actually hold a Korat’s attention, wand and puzzle styles are the sweet spot. I’ve rounded up the ones worth buying in the best interactive cat toys guide.
Korat weight: male vs female size
People search this exact question a lot, usually because their Korat feels heavier than it looks and they want to know if that’s normal. It is.
Rough weight ranges for a healthy adult:
- Female Korat: about 6 to 8 pounds
- Male Korat: about 8 to 10 pounds, sometimes a little over
Here’s the catch that trips up new owners. The Korat has a single, close-lying coat, so there’s no fluff padding out its silhouette. What you’re feeling is dense muscle over a fine frame. A Korat that looks small and slim can weigh more than a fluffier cat of the same visual size. That’s the “heavier than it looks” trait the breed is known for, and it’s a good thing. A Korat that feels bony or light for its length may be underweight or unwell, and that’s worth a vet check.
Don’t chase a target number on the scale. Use body condition instead: you should feel the ribs easily under a light layer, with a visible waist from above. Adjust food to keep that, not to hit “8 pounds.”
Korat health issues you actually need to know
The Korat is a long-lived, generally sturdy cat, with a typical lifespan of 12 to 16 years and plenty living longer. But there’s one genetic issue that dominates every honest conversation about this breed, and the internet usually explains it badly by lumping it into one word. There are two separate diseases.
GM1 and GM2 gangliosidosis (the big one)
These are inherited, recessive, fatal neurological storage diseases. “Recessive” means a kitten only develops the disease if it inherits a bad copy from both parents, and a carrier with one copy is perfectly healthy. There are two distinct forms in Korats:
- GM1 gangliosidosis is caused by a mutation in the GLB1 gene. Signs typically appear around 3 months of age, and affected kittens usually die by 8 to 10 months.
- GM2 gangliosidosis is caused by a mutation in the HEXB gene. It’s earlier and faster, with signs appearing around 4 weeks and death before 8 months.
Both are untreatable and heartbreaking. Both are also completely preventable with testing, which is the entire point of the next section.
The one thing you must ask every breeder
The University of California, Davis Veterinary Genetics Laboratory (UC Davis VGL) offers a DNA test that screens for both GM1 and GM2. A responsible Korat breeder tests their breeding cats and only pairs animals so that no kitten can be born affected.
Before you pay a deposit, ask the breeder directly:
- Have both parents been DNA tested for GM1 and GM2 through UC Davis VGL?
- Are the results N/N (clear) for both?
- Can I see the actual test certificates?
A good breeder will hand these over without hesitation. If a breeder gets vague, says “the line has always been healthy,” or can’t produce results, walk away. This is the single most important buyer-safety step for the entire breed, and no discount is worth skipping it.
Everyday health concerns
Beyond the genetic testing, Korats deal with the same things most cats do:
- Dental disease. Gingivitis and periodontal issues are common. Home brushing plus vet cleanings matter. Dental treats help between brushings but don’t replace them.
- Urinary tract issues. Korats can be prone to lower urinary tract problems and stones, which is largely a hydration story. More on that in feeding.
- Weight gain. An indoor Korat that isn’t played with will pad out. Watch portions and keep the play going.
Pet insurance is worth pricing out for a breed this expensive to acquire and this attached to specific genetic screening.
Korat vs Russian Blue: how to tell them apart
This is the comparison people get stuck on, because both are solid blue-gray cats with green eyes. They’re genuinely different breeds, though, and once you know what to look for it’s obvious.
- Coat: The Korat has a single coat that lies close to the body. The Russian Blue has a dense double coat that stands out from the skin and feels plush and springy. Run your hand down the back. One layer, Korat. Two, Russian Blue.
- Head shape: The Korat’s face is heart-shaped and rounded. The Russian Blue’s head is more wedge-shaped and angular.
- Ears: The Russian Blue’s ears are large and set more upright on top of the head. The Korat’s are large but flare more to the side.
- Body: The Korat is compact and surprisingly heavy for its size. The Russian Blue is finer-boned and more slender under all that coat.
- Temperament: Both bond hard to their people, but the Russian Blue is typically shyer and more reserved with strangers, while the Korat is a bit more forward and demanding of interaction.
- Coat color rule: The Korat standard allows only blue with silver tipping, and no white markings or tabby. The Russian Blue is also solid blue, so color alone won’t separate them. Use coat texture and head shape.
If you’re actively cross-shopping the two, the Russian Blue breed guide goes deeper on that side.
Price, rarity, and finding a real breeder
Korats are one of the harder purebred cats to buy, simply because so few people breed them. That drives the two things prospective owners run into: cost and waiting.
- Price: Roughly $1,200 to $2,000 for a pet-quality kitten from a registered breeder in 2026. Show or breeding-quality kittens go higher. If you see a Korat for $400 with no paperwork, assume it isn’t a health-tested purebred.
- Waitlists: Six to twelve months is normal. Many breeders have one or two litters a year. Getting on a list early is the game.
- Where to look: Start with the Cat Fanciers’ Association breeder directory and Korat Cat Fanciers, Inc. Ask each breeder about GM1/GM2 testing (see above), how they socialize kittens, and their health guarantee.
- Red flags: No genetic testing, kittens available “right now” with no questions asked, prices far below range, or a seller who won’t let you see the parents or the kittens’ living conditions.
Rescue is rare for this breed but not impossible. Breed-specific and Thai-cat rescues occasionally have Korats or Korat mixes, and the CFA sometimes lists rehoming adults.
What to feed a Korat
Feeding a Korat isn’t complicated, but two things deserve attention: protein quality and hydration.
The basics
Pick a food labeled complete and balanced to AAFCO standards for the right life stage. Korats are muscular, active cats, so a named animal protein (chicken, turkey, fish) as the first ingredient is what you want, not a corn or by-product-heavy filler food. If you’re not sure how to read a label, the how to pick cat food walkthrough covers what actually matters.
Hydration matters more for this breed
Because Korats lean toward urinary tract issues, water intake is worth engineering, not leaving to chance. Cats are famously bad at drinking enough on their own. Feeding at least some wet food, adding a water fountain, and keeping bowls topped up all help dilute urine and lower stone risk. If your Korat has had urinary trouble, a vet-recommended urinary-tract diet is worth discussing.
How much and by life stage
Skip the flat “200 to 300 calories a day” advice, because it ignores your specific cat. Portion by weight and condition instead:
- Kittens grow fast and eat a lot for their size. Feed a kitten-formula food, often free-fed or in three to four meals a day, until about 12 months.
- Adults do best on measured meals twice a day. Start with the package guideline for your cat’s weight, then adjust up or down based on body condition over a few weeks.
- Seniors (roughly 8 years and up) often need fewer calories but still high protein to hold muscle. Watch for weight creep or unexplained loss, both worth a vet visit.
Weigh your cat every month or two and keep checking those ribs. The scale plus the hands-on check together tell you more than any calorie chart.
Grooming a Korat (the easy part)
Good news: the single coat is about as low-effort as cat grooming gets.
- Brushing: Once a week with a soft brush or a grooming glove is plenty. It lifts loose hair and doubles as a bonding session, which a Korat loves. During spring and fall you might bump it to twice a week. A soft brush or grooming glove is really all the coat needs. No de-shedding rake required.
- Bathing: Rarely needed. Korats are fastidious self-groomers. Only bathe if your cat gets into something, and use a gentle cat shampoo.
- Nails: Trim every two to three weeks with cat clippers. Start young and pair it with treats so it stays a non-event.
- Teeth: This is the grooming task that actually earns its keep for a Korat. Brush several times a week with cat toothpaste, never human toothpaste. Given the breed’s dental tendencies, this small habit saves real money and discomfort later.
Exercise and enrichment
Korats are moderately active and, more importantly, mentally engaged. They don’t need a huge amount of space, but they do need interaction and something to climb.
Aim for a couple of genuine play sessions a day. Wand toys that let you mimic prey are their favorite, and puzzle feeders turn mealtime into a small hunt, which suits their problem-solving brain. Give them vertical space too: a cat tree, a tall perch, or a cleared windowsill for bird-watching. A bored Korat gets clingy and can pick up nuisance habits, so the enrichment isn’t optional fluff, it’s how you keep the cat balanced.
They’re indoor cats by nature and safety, but many happily learn to walk on a harness or enjoy a secure catio.
Who a Korat is right for (and who should skip it)
A Korat suits you if you want a deeply affectionate, people-focused cat, you’re home enough that it won’t be lonely, you have the patience for a waitlist and the budget for a well-bred kitten, and you’re comfortable insisting on GM1/GM2 testing before you buy.
Skip the Korat if you’re out of the house 12 hours a day and want a self-sufficient cat, you have a loud and chaotic household that would stress a sensitive breed, you want a specific look on a budget, or you’re not prepared to verify health testing. This is a companion animal first. It gives a lot and it expects a lot back.
