Cornish Rex

Cornish Rex Overview

Discovered in a Cornwall farm litter in 1950, just a decade before the similarly-curled Devon Rex was found in a neighboring county, the Cornish Rex's curl comes from a distinct genetic mutation that eliminates the outer guard hairs entirely, leaving only the soft undercoat — a texture often compared to crushed velvet or rabbit fur. This near-total absence of a protective outer coat leaves Cornish Rex cats notably cold-sensitive and prone to sunburn, but it also produces one of the lowest-shedding breeds available, and the breed's springy, arch-backed body combined with an almost frantic playfulness has earned it comparisons to a small, perpetually energetic greyhound.

Temperament

• Extremely energetic and acrobatic
• Highly people-oriented, seeks constant interaction
• Playful and mischievous well into adulthood

Full Breed Facts

• Hypertrophic cardiomyopathy
• Patellar luxation

Care Tips

• Keep indoor temperatures warm and provide blankets or sweaters given minimal natural insulation
• Bathe occasionally to manage skin oil, similar to hairless breeds, given the reduced coat
• Provide extensive daily play — this breed's activity level is genuinely higher than most

Is the Cornish Rex Right for You?

The Cornish Rex tends to suit owners who can genuinely meet its engagement needs and grooming demands. Before committing to this breed, it's worth spending time with an adult individual (not just a puppy or kitten, whose adult temperament isn't yet fully expressed) to confirm the fit feels right for your household and daily routine.
