The earliest known picture of a Korat (or Si-Sawat) cat is found in Bangkok’s National Library in Thailand, in the ancient book of paintings and verses known as "The Cat-Book Poems." It is believed to have been produced some time during the Ayudhya Period of Siamese History (1350-1767).
Korats are considered a symbol of good fortune by the Thais, and indeed, many good-luck traditions surround the breed: They are the color of silver, signifying wealth, as well as the color of rain clouds, with eyes the color of young rice, meaning good crops. The gift of a pair of Si-Sawat cats to a bride is said to ensure a fortunate marriage.
Like all newborn kittens, at first the eyes are blue, changing to amber with a green tinge around the pupil during adolescence. Then, when the cat reaches approximately two to four years of age, the eyes become luminous green. The breed's coat, however, does not change color. Korats are silver-blue from their first day until their last; a cat of any other color is not a Korat.
Korats have extraordinary powers of hearing, sight, and scent. They are gentle pets, moving softly and cautiously, disliking sudden, loud, or harsh noises. They form an exceptionally strong bond of affection with their owners and respond warmly to cuddling, setting as close as possible. They mix well with other cats, but tend to want to have the upper hand and will not let the others keep them from their rightful place at their owner’s side. Korats are active in their play, but are very gentle with children. They have been cherished for centuries in their native Thailand and they naturally expect this tradition to be maintained wherever they go.
