The Korat is one of the oldest and most culturally significant cat breeds in the world, with roots reaching deep into the history of Thailand, formerly known as Siam. The earliest known description of the Korat appears in the Tamra Maew, or "Cat-Book Poems," a collection of illustrated manuscripts believed to date from the Ayutthaya Kingdom between 1350 and 1767. In these texts the breed is called the Si-Sawat, a name that references its distinctive blue-grey coat and connects it to prosperity and good fortune.
The Korat's homeland is the Nakhon Ratchasima province in northeastern Thailand, historically referred to as Korat. The breed takes its modern Western name from this region, and local folklore holds that the Si-Sawat cat was never bought or sold but only given as a gift, reinforcing its status as a living symbol of respect and goodwill. The cats were treasured by Thai families of all social classes, and their presence in a household was considered an omen of rain and a plentiful harvest.
Unlike many breeds that were shaped by deliberate human breeding programs, the Korat evolved largely through natural selection in its native region. Its compact, muscular body, luminous green eyes, and single silver-tipped coat developed over centuries without significant outside genetic influence. This natural purity is a point of pride among breed enthusiasts and has been carefully maintained as the Korat moved into the Western cat fancy during the twentieth century.
Early Western travelers to Siam occasionally noted the presence of striking blue cats, but formal breed recognition in the West did not begin until the mid-twentieth century. The first documented pair of Korats arrived in the United States in 1959, imported by Jean Johnson, a breeder who had lived in Thailand and recognized the breed's unique qualities. From that foundation, careful breeding programs expanded the Korat's presence across North America and later into Europe and beyond.
