Breed Origins and History
Cornish Rex Origins
The Cornish Rex originated in Cornwall, England, in 1950 with the birth of a curly-coated barn cat kitten named Kallibunker.

Genetic Background:

Devon Rex Origins
The Devon Rex emerged independently in Devon, England, approximately a decade later from a litter of stray cats.

Genetic Discovery:
