For cat lovers seeking a unique, low-shedding companion with elfin charm, the Devon Rex and Cornish Rex are captivating choices. While both share a distinctive curly coat and playful spirit, they are genetically distinct breeds with different histories, appearances, and temperaments. This comprehensive guide provides the essential comparison to help you choose the right pixie-faced feline for your home.
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.
