Cornish Rex

The Sleek Curly-Coated Athlete

Cornish Rex cats are sleek, athletic, and uniquely coated. Unlike the Devon Rex, their curly fur comes from a different gene and consists of only the soft undercoat with no guard or awn hairs. They feel warm to the touch, have a racing metabolism, and are exceptional jumpers.

Why Cornish Rex Cats Are Built for Speed and Fun

Undercoat Only

Cornish Rex have only the soft down undercoat, lacking the guard and awn hairs other cats have. This creates their signature marcel-wave curls and velvety feel.

Exceptional Athletes

With their lean, muscular bodies and arched backs, Cornish Rex are incredible jumpers and sprinters. They can leap to surprising heights with ease.

Warm to the Touch

Their thin coat makes them feel warmer than other cats. They seek heat sources and love to cuddle, but can sunburn easily without protection.

Racing Metabolism

Their fast metabolism means they eat more relative to their size and stay lean. They burn energy quickly and rarely struggle with obesity.

Pros

  • Minimal shedding with their unique undercoat-only fur
  • Affectionate and love human companionship
  • Highly intelligent and trainable
  • Generally healthy and long-lived

Cons

  • Sensitive to cold temperatures and drafts
  • Can sunburn through windows or outdoors
  • High energy demands consistent interactive play
  • Not truly hypoallergenic despite reduced shedding
  • Fragile coat requires gentle handling
