Greyhound of the cat world — narrow body, long legs, arched back, tucked belly. The wave-pattern coat (marcel waves rather than Devon's curls) is uniquely soft. Cornish Rexes never quite stop being kittens, mentally — even at age 12 they'll chase a string until you collapse from boredom.

Cornish Rex temperament

Extremely active, intelligent, persistent. Will train you to throw toys. More extroverted than Devon — louder, more vocal, more in-your-business. Excellent jumpers; expect them on top of bookcases.

History in Australia

First Cornish Rex (Kallibunker) born on a farm in Cornwall, 1950. Different recessive gene from the Devon Rex despite similar appearance. Established in Australia by the 1980s.

Who the Cornish Rex suits

Good for:

Active households
Allergy-conscious owners (lower shedding)
Households wanting a permanently-kitten-like cat

Watch out for:

Cold-sensitive
High prey drive — toy obsessed
Loud and chatty

Caring for a Cornish Rex

Weekly bath because oil builds up on the thin coat. Provide a cat tree (they're climbers and need vertical territory). They get cold; provide warm sleeping spots in winter.

Owning a Cornish Rex in Australia — the essentials

Beyond the breed-specific notes above, every Australian cat owner needs to know:

Microchipping: Mandatory in every state and territory before sale or transfer (NSW: by 12 weeks; VIC: before sale; QLD: by 12 weeks). Around $60–80 at most vets.
Desexing: Required by 4 months in the ACT and parts of VIC; strongly encouraged everywhere else. Many councils discount registration for desexed cats.
Cat containment: 24/7 containment is now law in the ACT (territory-wide since 2022) and 40+ Victorian councils. Other states are following — assume your council requires it within a few years and build a catio.
Registration: Most AU councils require cat registration by 12 weeks. Annual fee typically $25–80, lower for desexed cats.
Vet costs: Budget $300–600/year for routine care (annual checkup, vaccinations, parasite prevention) plus an emergency fund of at least $2,000 — a single dental procedure or blocked-bladder treatment can hit $1,500–3,500.

Common Cornish Rex health issues

Hypertrophic cardiomyopathy
Hereditary patellar luxation
Hyperthyroidism (older cats)

Frequently asked questions

Cornish Rex vs Devon Rex — which should I pick?

Cornish for active, dog-like, marathon play sessions and a slightly less demanding personality. Devon for goofier, more 'velcro cat' attachment and a tougher constitution. Coats differ too — Cornish is wave-patterned, Devon is curly tufts.
