Devon Rex Origins

A Curly Discovery:

• The breed began in 1960 in Devon, England, with a curly-coated barn cat named Kirlee.
• Initially thought to be related to the Cornish Rex, genetic testing proved it was a separate, unique mutation.

Breed Development:

• Early breeding attempts with Cornish Rex produced straight-coated kittens, confirming the different gene.
• Breeders carefully preserved the breed's unique elfin characteristics.
• The Devon Rex gained CFA recognition in 1979.

Key Genetics:

• The curly coat is also a recessive gene, distinct from the Cornish Rex.
• It produces a soft, wavy coat with curled or often absent whiskers.
