Three Rex Breeds, Three Different Stories
The term "rex" in cat breeding refers to a genetic mutation that causes the coat to grow in a wavy or curly pattern rather than straight. Three breeds share this characteristic in the most well-known way: the German Rex, the Cornish Rex, and the Devon Rex. While they may look similar at a glance, these are genetically and physically distinct breeds — each with its own personality, coat type, and care requirements.
Origins at a Glance
| Breed | Country of Origin | First Recorded |
|---|---|---|
| German Rex | Germany | 1930s–1950s |
| Cornish Rex | England (Cornwall) | 1950 |
| Devon Rex | England (Devon) | 1960 |
The German Rex is the oldest of the three, though its recognition came later due to post-war isolation. All three arose from independent natural mutations rather than human-directed breeding programs.
Coat Comparison
The coat is the most obvious difference between these breeds, and it matters for both appearance and grooming:
- German Rex: Soft, plush, medium-length wavy curls. Has all three hair types (guard, awn, and down hairs), giving a fuller, more substantial feel.
- Cornish Rex: Very short, fine, and tightly waved — almost like rippled velvet. Lacks guard hairs entirely, making the coat feel ultra-silky. Shares the same gene mutation as the German Rex.
- Devon Rex: Short, loose, very fine curls with a slightly coarser texture. Also lacks guard hairs. The Devon Rex gene is a different mutation from the German and Cornish Rex.
Body Type Comparison
- German Rex: Muscular and cobby (rounded, compact). Medium-sized with a round head and large, open eyes.
- Cornish Rex: Slender, elegant, and long-bodied with a distinctly arched back. Resembles a small whippet in structure.
- Devon Rex: Medium-sized with a distinctive large head, prominent cheekbones, and very large, wide-set ears — often described as "pixie-like."
Personality Differences
All three breeds are social and people-oriented, but there are nuanced differences in personality:
- German Rex: Affectionate, playful, and intelligent. Generally calm enough to suit families and multi-pet households without being demanding.
- Cornish Rex: Highly energetic, acrobatic, and intensely playful. Often described as the most "dog-like" of the three. Can be boisterous and requires a lot of stimulation.
- Devon Rex: Extremely people-focused and often described as mischievous. They love to perch on shoulders and be close to their humans at all times. Deeply loyal but also quite cheeky.
Which Rex Breed Is Right for You?
Choosing between these three comes down to lifestyle and what you're looking for in a feline companion:
- Choose the German Rex if you want a well-rounded, affectionate companion with a fuller coat and a slightly calmer disposition — and you appreciate owning a rare breed with deep historical roots.
- Choose the Cornish Rex if you want an athletic, high-energy cat that will keep you entertained with acrobatic antics and doesn't want to miss a thing.
- Choose the Devon Rex if you want a deeply bonded, velcro-cat with a pixie personality that will follow you everywhere and charm everyone it meets.
One Thing They All Share
Despite their differences, German Rex, Cornish Rex, and Devon Rex cats all share a love of human company, a keen intelligence, and a sensitivity to cold temperatures (due to their reduced coat insulation). All three thrive as indoor cats in warm, loving households. Whichever curly-coated cat you choose, you're bringing home a remarkable, one-of-a-kind companion.
