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.

Development Timeline:

  • 1950: Kallibunker is born on Bodmin Moor.
  • 1957: The breed is imported to the United States.
  • 1962: Achieves championship status with the Cat Fanciers' Association (CFA).
  • Today: Recognized and cherished by cat associations worldwide.

Genetic Background:

  • Result of a natural recessive gene mutation.
  • The term "Rex" is borrowed from similarly coated rabbits.
  • Developed through careful, selective breeding programs.

Devon Rex Origins

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

Development Timeline:

  • 1960: Kirlee, the foundation cat, is born near Buckfastleigh.
  • 1968: Gains formal recognition in the United Kingdom.
  • 1979: Awarded CFA championship status.
  • Today: A popular and beloved breed globally.

Genetic Discovery:

  • Initially mistaken for a Cornish Rex variant.
  • Proven to be caused by a completely different gene.
  • Crossing the two breeds produces only straight-coated offspring, confirming their genetic separation.

Key Historical Difference: Despite their similar curly coats, the Cornish and Devon Rex mutations are genetically unrelated. They are distinct breeds that developed independently.
