The name "Khao Manee" (pronounced "cow mah-nee") comes from the Thai language, where "Khao" means white and "Manee" means jewel or gem. The name translates to "White Gem" or "White Jewel," perfectly describing this breed's pure white coat and jewel-like eyes. This poetic name reflects the breed's status in Thai culture, where these cats were treasured by royalty and nobility for centuries.
The breed is also known by several other traditional Thai names. "Khao Plort" means "all white," another straightforward description emphasizing the breed's defining characteristic. The name "Diamond Eye" is used internationally, particularly in English-speaking countries, referring to the breed's stunning eyes that sparkle like precious gems. This nickname is especially appropriate for odd-eyed Khao Manees, whose mismatched eyes—one blue and one gold or green—are particularly prized and striking.
Historically, these cats appear in the Tamra Maew (Cat-Book Poems), an ancient Thai manuscript dating to the Ayutthaya Kingdom period (1351-1767). In this text, they're described as one of the good luck cats, believed to bring prosperity, longevity, and good fortune to their owners. The manuscript depicts several Thai cat breeds, but the all-white cats with jewel-like eyes hold special significance, reserved for royalty and those of high social standing.
In Thailand, the breed is sometimes simply called "white cat" when distinguishing it from other Thai breeds like the Siamese (originally called Wichien-Maat) or Korat. However, true Khao Manees are distinct from random white cats due to their specific genetic heritage, body type, and the particular eye colors that define the breed. Not all white cats are Khao Manees—the breed has specific standards regarding body structure, head shape, and eye characteristics.
The breed gained official recognition relatively recently in Western cat registries. The International Cat Association (TICA) granted registration status in 2009 and championship status in 2015. The Cat Fanciers' Association (CFA) accepted the breed into its Miscellaneous class in 2015 and granted championship status in 2018. Other international registries have followed suit, though the breed remains rare outside Thailand. The rapid recognition reflects both the breed's ancient heritage and its immediate appeal to cat enthusiasts worldwide.
Some breeders and enthusiasts outside Thailand informally call them "Royal Cats of Siam" due to their historical association with Thai royalty, though this nickname isn't official and can cause confusion with other Thai breeds. The Khao Manee's royal history is well-documented—King Chulalongkorn (Rama V, 1868-1910) kept these cats, and they were among the most prized possessions of the Thai royal court. Today, the breed represents both Thailand's cultural heritage and a living connection to centuries of selective breeding by Thai nobility.
