The Suphalak is a rare, naturally occurring cat variety from Thailand whose documented history reaches back to the Ayutthaya Kingdom (1351–1767). Its earliest descriptions appear in the Tamra Maew, a body of illustrated Thai manuscripts known in English as the Treatise on Cats or Cat-Book Poems, which catalogued the cats considered auspicious enough to keep and breed.
In those manuscripts the breed is referred to as Thong Daeng, a Thai term meaning copper or red gold, a reference to its solid, even, reddish-brown coat. The same poems describe the cat as magnificent and compare its rarity to that of gold itself.
Because the Suphalak shares a warm brown coloration with the Burmese, it is frequently described as an ancestor of the modern Burmese breed. Others classify it not as a distinct breed at all but as a color variety of the broader native Thai landrace known as the Maew Boran, or ancient cat.
Whatever its precise taxonomic status, the Suphalak developed as a pure Thai cat without deliberate outcrossing to foreign breeds, which is one reason modern preservationists treat it as a heritage variety rather than a manufactured show breed.
