Khao Manee: At a Glance
The Khao Manee — 'White Gem' in Thai — is an ancient royal breed from Thailand known for its pure white coat and striking odd-colored eyes (one blue, one gold).

Khao Manee Eye Color Genetics
Khao Manee Care Essentials
| Hearing test for kittens — white cats have higher deafness risk | |
| Sun protection — white cats are prone to sunburn on ears/nose | |
| Regular vet eye exams — monitor for eye health issues | |
| Indoor-only lifestyle — white cats are more visible to predators | |
| Provide interactive play — they're intelligent and need stimulation | |
| Assume all white cats are deaf — many hear perfectly well | |
| Skip sunscreen — pet-safe sunscreen on ear tips is important outdoors | |
| Breed without genetic testing — deafness and eye issues can be inherited |
The 'odd-eyed' Khao Manee — one blue eye, one gold eye — is the most prized and iconic. This trait is caused by the white spotting gene affecting melanin migration during development. Odd-eyed cats are not necessarily deaf, but hearing should be tested.
White cats with blue eyes have a higher risk of congenital deafness. This is due to the same gene that causes the white coat affecting the inner ear. Responsible breeders test kittens' hearing via BAER testing before placement.
The Khao Manee (Thai for "white gem") is an ancient all-white Thai cat breed with a documented history in Thai literature dating to the 13th century. Considered lucky and kept by Thai royalty for centuries, they were not exported outside Thailand until the early 2000s. The breed is now recognized by TICA and gaining a small following internationally, prized for their vivid odd-eyed or jewel-bright colored eyes and their outgoing, communicative personality.
Eye Color Is the Breed's Most Distinctive Variable
Khao Manees may have two blue eyes, two gold eyes, two different-colored eyes (one blue, one gold -- the most highly prized combination in Thai tradition, called "diamond eyes"), or occasionally green eyes. Eye color is not correlated with deafness in this breed at the same rate as other all-white cats because the white coat color in Khao Manees is produced by a different genetic mechanism than the dominant white gene (W gene) that causes deafness in most white cats. This is a critical distinction -- the W gene causes melanocyte-related deafness; Khao Manee white is believed to be produced by a different locus, though the genetics are not yet fully characterized in peer-reviewed literature.
Deafness Testing Is Still Recommended
Despite the theoretical difference in white coat genetics, responsible Khao Manee breeders test all breeding stock and kittens for deafness using BAER (Brainstem Auditory Evoked Response) testing. White cats with blue eyes from any white breed have elevated deafness risk; odd-eyed white cats have intermediate risk (deafness more common on the blue-eyed side). Khao Manees with documented BAER test results are the appropriate choice for breeding programs and for households with young children where communication clarity matters. BAER testing is available at veterinary neurology specialists and some university teaching hospitals.
Personality Is Highly Interactive and Vocal
Khao Manees are described uniformly as outgoing, curious, people-seeking cats that participate actively in household activity. They are more vocal than average domestic cats but less demanding than Siamese. Their Thai origin as companion cats to royalty -- rather than working or hunting cats -- produced a temperament oriented entirely toward human interaction. They engage well with visitors (unlike more reserved breeds), adapt to new environments with reasonable speed, and are considered appropriate for households with children and other pets when properly introduced.
Population Outside Thailand Is Still Small
Khao Manee breeding programs outside Thailand are concentrated in the US, UK, and Europe. The Khao Manee Cat Club of America maintains a breeder registry. Waiting lists of 6--18 months are common. The majority of Khao Manees in the US are from bloodlines imported since 2007; the founding population was small, making genetic diversity monitoring an active responsibility for the breed community. TICA's advanced new breed registration provides a pathway to championship status as registration numbers grow.
Care Requirements Are Standard Domestic Cat Husbandry
Khao Manees are medium-sized cats (6--10 lbs) with a short, close-lying all-white coat that requires minimal grooming -- weekly brushing is sufficient to manage shedding. Indoor-only housing is standard; a white cat outdoors is visible to predators and sunburn-susceptible on the ears (squamous cell carcinoma on the ears of white cats with pink skin is a documented long-term risk with sun exposure). Annual wellness exams, core vaccinations, dental care, and environmental enrichment appropriate for an active, intelligent cat round out their care requirements. Lifespan averages 14--18 years.
