Origins and History
Cornish Rex History
The Cornish Rex originated in Cornwall, England, in 1950 with the birth of a cream-colored kitten named Kallibunker. This kitten possessed an unusual curly coat resulting from a spontaneous genetic mutation that produced only the soft undercoat (down hair), lacking the typical guard and awn hairs.
Breeders recognized this unique trait and began a dedicated breeding program. The Cornish Rex achieved championship status in cat associations during the 1960s. It's crucial to note that despite their similar names, the Cornish and Devon Rex mutations are genetically distinct and not directly related.
Devon Rex History
The Devon Rex emerged a decade later in Devon, England, in 1960. A stray cat gave birth to a curly-coated male kitten named Kirlee. Initially assumed to be related to the Cornish Rex, test breedings proved the Devon's curly coat was caused by a completely different genetic mutation.
This mutation affects all three hair types but creates a unique curl. The breed gained recognition in the UK in the 1960s and was accepted in the United States by the 1970s.
