Field Notes
Korat Lifespan, Size, and Care
The Korat is one of Thailand’s oldest natural cat breeds and has long been associated with good luck and prosperity. Traditionally called the "Si-Sawat," it appears in historic Thai writings and was often given as a gift rather than sold. The breed became known internationally in the 20th century, but it remains relatively uncommon outside its native country.
Korat cats are deeply attached to their people and often prefer close companionship over independence. They are typically gentle, observant, and sensitive to household routines, and many do best in calm homes where they receive plenty of interaction. While affectionate, they can be reserved with strangers and may dislike loud, chaotic environments.
Care for a Korat is fairly straightforward because the breed has a short, single coat that does not mat easily. Regular veterinary visits, dental care, portion control, and high-quality nutrition are especially important, since these cats can become overweight if overfed and underexercised. Reputable breeders should screen for inherited gangliosidosis, a serious genetic disorder known in the breed.
Korats are moderately active cats that enjoy interactive play, climbing opportunities, and puzzle toys that engage their quick minds. They usually do not require intense exercise, but they benefit from daily play sessions to maintain muscle tone and prevent boredom. Because they are people-focused, they often enjoy games that involve direct interaction with their owners more than solitary play.

Korat Feeding Guide
Use this Korat feeding guide as a starting point for common life stages, then adjust for body condition, activity, and veterinary advice.
Formative years
Young
Feed a complete kitten formula in several small measured meals each day, with the exact amount adjusted to growth rate and body condition. Kittens should stay on a growth diet until your veterinarian confirms they are ready for adult food.
Peak years
Adult
Feed a complete adult cat food in measured portions and monitor body condition closely, because indoor cats often need fewer calories than owners expect. Wet food, fresh water, and routine portion checks help reduce weight gain and support urinary health.
Mature years
Senior
Older cats often need closer monitoring of weight, appetite, hydration, and dental comfort even before a full diet change is needed. Ask your veterinarian about senior diets if kidney disease, thyroid disease, muscle loss, or digestive changes start to affect intake.
Questions, Answered
On the Korat
That depends on the pet's actual age. Use the calculator above to estimate a Korat's age in human years using the method shown on this page.
Most Korats live 10-15 years, although genetics, diet, body condition, husbandry, and preventive care all influence the real outcome.
A full grown Korat usually weighs 3-5 kg, though sex, lineage, and body condition can move an individual above or below the average range.
Most Korats are close to full size around 12-18 months, although growth rate and final build vary from one pet to another.
Use the feeding guide above as a starting point, then adjust for age, body condition, activity, and your veterinarian's recommendations.
Korat cats can make excellent family pets when they live in a calm, respectful home. They are affectionate and loyal, but they tend to be emotionally sensitive, so they usually do best with gentle children and adults who handle them quietly and consistently.
No, Korats are relatively low-maintenance because they have a short single coat with minimal matting. A weekly brushing is usually enough to remove loose hair and keep the coat glossy, though routine nail trimming and dental care are still important.
Yes, the most notable inherited concerns in Korats are GM1 and GM2 gangliosidosis, which are serious neurologic storage diseases. Responsible breeders test breeding cats for these conditions, so owners should always ask for health screening documentation before acquiring a kitten.
Korats are playful and alert but not usually hyperactive. They benefit from daily interactive play, climbing furniture, and enrichment toys to keep them mentally stimulated and to reduce the risk of weight gain.
Korats are strongly people-oriented and may become lonely or stressed if left alone too often. If a household is away for much of the day, providing enrichment, a predictable routine, and in some cases a compatible companion animal may help them cope better.
