Oregon Rex

Breed Profile

The Oregon Rex is a fascinating footnote in feline history—a breed that flashed into existence like a comet and then faded away. Known for its distinct curly coat and petite frame, this American breed is now considered extinct, having been absorbed into other Rex breeds.

History: The Rise and Fall

The story began in 1944 in Oregon, USA, when a single kitten with wavy fur was born in a litter of otherwise normal farm cats. This kitten was the result of a spontaneous genetic mutation. Breeders at the time recognized the uniqueness of the coat and attempted to establish a line.

However, the timing was unfortunate. Around the same period, the Cornish Rex (from the UK) and later the Devon Rex were gaining popularity. Breeders, in an attempt to strengthen the Oregon Rex line, crossed them with these British imports.

What they didn’t realize initially was that the gene for the Oregon Rex coat was distinct from the Cornish and Devon genes. By constantly outcrossing, the specific Oregon gene was diluted. The resulting kittens often looked like Rex cats, but genetically, they were becoming Cornish Rexes. The last purebred Oregon Rex is believed to have died in 1972, marking the end of the breed as a unique genetic entity.

Personality: The Classic Rex Temperament

Historical accounts of the Oregon Rex describe a personality very similar to its surviving cousins. They were known for being:

• Affectionate: They were described as “Velcro cats” who hated being alone.
• Playful: High energy and acrobatic.
• Demanding: They had a reputation for being somewhat arrogant or bossy, demanding attention on their terms.

Appearance

The Oregon Rex was a small-to-medium cat with a petite, elongated frame. The defining feature was the coat: short, silky, and arranged in tight curls or waves. Unlike the Cornish Rex, which lacks guard hairs, the Oregon Rex had a different coat texture, though to the untrained eye, they looked quite similar.

They had a wedge-shaped head, large ears with rounded tips, and oval eyes. Their legs were long and slender, contributing to an elegant, athletic appearance.

Why Did It Disappear?

The extinction of the Oregon Rex is a lesson in genetics. The gene causing the curl was recessive. When an Oregon Rex was bred to a Cornish Rex, the resulting kittens often had straight hair (because the two mutations were on different genes, and neither parent provided the matching recessive gene for the other). This confused early breeders.

Over time, the stronger, more established populations of Cornish and Devon Rexes simply overwhelmed the small Oregon gene pool. Today, the “Oregon Rex” lives on only in old photographs and breeding records.
