What Makes Korat Cats Special
The Korat's silver sheen comes from pale silver tips on blue hair shafts, becoming most brilliant where the coat is shortest.
Multiple heart shapes are celebrated: the head viewed from the front, the nose, the chest when seated, and the muscular outline of the shoulders.
Korat Cat History & Origin
The Korat, traditionally called Si-Sawat, is one of the auspicious Thai cats described in the Tamra Maew manuscripts. Its rain-cloud color, seedling-green eyes, and repeated heart shapes symbolize prosperity, harvest, happiness, and marriage luck.
Thai tradition gave Korats in pairs rather than selling them, especially as wedding gifts.
Nara and Darra, presented to Jean Johnson, became the first documented breeding pair imported to the United States in 1959.
Modern pedigrees remain connected to native Thai cats, earning the phrase 'silver-blue cat with the Thai passport.'
Korat Cat Characteristics
Individual Variation
Cats are individuals and not all cats, even those of the same breed, will exhibit all the same qualities.

Shedding Level
Korat Cat Appearance
This is a small-to-medium, semi-cobby cat with smooth curves, a broad chest, strong muscle, and much greater heft than its size suggests.
Only one presentation defines the traditional breed: a short silver-tipped blue coat without patches or markings, eventually paired with luminous peridot-green eyes.
Physical Features
Ears
Large, round-tipped, wide at the base, high-set, alert, and sparsely furnished inside.
Eyes
Very large, luminous, alert, and round when open, with peridot green preferred at maturity.
Nose
Short with a gentle lion-like downward curve and a slight stop; leather is dark blue to lavender.
Coat & Build
Tail
Medium, heavier at the base and tapering to a rounded tip, proportionate to the body.

The Korat's silver sheen comes from pale silver tips on blue hair shafts, becoming most brilliant where the coat is shortest.

Health
Korats are often long-lived, but the breed has two serious autosomal-recessive lysosomal storage disorders, GM1 and GM2 gangliosidosis. Reliable DNA tests make affected matings preventable, so documented results are a basic responsibility rather than an optional extra.
Common Health Issues
Preventive Care
Verify both parents' laboratory results for the specific Korat GM1 and GM2 variants; carriers can be healthy but must never be paired with another carrier of the same disorder. Preserve diversity through informed pedigrees, maintain dental care and lean weight, and screen senior cats for renal, thyroid, cardiac, and blood-pressure changes.
Caring for Your Korat Cat
Grooming Requirements
The fine, glossy single coat lies close to the body and has no woolly undercoat, so grooming is quick and shedding is usually modest.
Brushing
Brush weekly with a soft bristle brush or chamois, increasing briefly when seasonal loose hair appears. Avoid rough tools that can break the silver-tipped hairs.
Bathing
Bathe only when dirty or before a show with a mild cat-safe shampoo. Rinse well and avoid products that alter the coat's natural blue tone or silver sheen.
Eye Care
Wipe minor discharge with a separate soft damp cloth for each eye; redness, cloudiness, pain, or a change in vision needs veterinary care.
Nail Care
Every 2-3 weeks.
Essential Grooming Tools
Exercise & Play
Energetic and intelligent without usually being frantic, the Korat enjoys running, jumping, retrieval, and games that reward close cooperation with familiar people.
Daily Requirements
Provide about 40-50 minutes of interactive play in several sessions, plus secure climbing, scratching, and independent puzzle opportunities.
Mental Stimulation
Teach practical cues and tricks, rotate puzzles, hide part of the ration, and offer safe window observation. Korats learn household patterns quickly and can become demanding when ignored.
Recommended Activities
Nutrition & Feeding
Feed a complete-and-balanced life-stage diet that preserves the Korat's characteristic hard muscle and substantial feel without allowing a fat pad to disguise body condition.
Daily Amount
Use the manufacturer's feeding guide as an initial estimate, measure the full daily ration, divide it among two or more meals and training rewards, and adjust with a veterinarian according to body condition and activity.
Special Considerations
No special breed diet is established. Wet food and several fresh-water stations can support hydration, while measured puzzle feeding provides mental work without accidental overfeeding.
Living Environment
Space Requirements
Adapts to apartments or houses with stable climbing routes, scratching surfaces, hiding places, running room, and frequent family interaction.
Climate Preferences
The close single coat offers limited insulation. Keep indoors with warm beds in cold conditions and cooling, shade, and fresh water in heat.
Ideal Lifestyle Match
Best in a predictable, affectionate home where it can participate in daily life. Korats may be selective or possessive about preferred people and often enjoy another Korat, but all pet introductions should be gradual.
Colors & Patterns
The Korat is a one-color breed. Each hair is blue with a paler root and silver tip, producing a distinctive shimmering halo rather than a flat gray coat.

Fun Facts About Korat Cat
The Korat's traditional Thai name is Si-Sawat.
Its silver-tipped blue coat is the only accepted traditional color.
Adult green eye color may take two to four years to mature.
Korats often feel unexpectedly heavy because of dense muscle.
Thai tradition associates the breed with rain, harvests, wealth, and fortunate marriages.
The first documented U.S. pair, Nara and Darra, arrived in 1959.
Separate DNA tests are available for Korat GM1 and GM2 gangliosidosis.
A healthy carrier of a recessive gangliosidosis variant must never be bred to another carrier of that same variant.

Frequently Asked Questions
Is every solid blue cat a Korat?
No. A pedigree Korat has documented Thai-derived ancestry plus a specific heart-shaped head, single silver-tipped blue coat, muscular body, and green adult eyes; coat color alone cannot identify the breed.
Why might a Korat kitten have amber eyes?
The luminous green adult color develops slowly. Kittens often have amber or yellow-green eyes, and the preferred final shade may not appear until two to four years of age.
What health tests should Korat breeders perform?
At minimum, breeding plans should include documented DNA status for both the Korat-associated GM1 and GM2 gangliosidosis variants so two carriers of the same disorder are never paired.
Specialized Care Guides
Kitten Care
Review laboratory certificates for both GM1 and GM2, socialize positively, begin dental care, weekly brushing, carrier training, and measured feeding, and provide safe climbing and learning games from the start.
Senior Care
Schedule veterinary checks every 6-12 months as advised, monitoring teeth, kidneys, thyroid, blood pressure, heart, weight, vision, hearing, and mobility while keeping games social and physically accessible.
First-Time Owner Tips
A good option for an attentive first-time owner who understands the breed's intense social bond, verifies GM1 and GM2 testing, and supplies daily training, play, and predictable companionship.
