Cornish Rexes originated in Cornwall in the 1950s following the birth of an unusually curly-haired and long-legged kitten. The curly hair was found to result from a genetic mutation, with the curly-haired gene being recessive. After breeding the kitten back to his mother, the resulting kittens were bred to British Shorthairs and Siamese cats to create the breed we know today.

Devon Rexes originated in nearby Devon in the 1960s and were initially considered Cornish Rexes. However, although the curly coat in Devon Rexes is also caused by a genetic mutation and is a recessive gene, it is not the same gene that Cornish Rexes are. This means that although they might look similar, they are actually genetically very different.

The 4 Key Differences Between Devon Rexes and Cornish Rexes

The first difference between these two unique cats is their size. Cornish Rexes can reach a slightly heavier weight than Devon Rexes – between 6 and 10 pounds, while Devon Rexes are 6 to 9 pounds. However, when it comes to their height, Devon Rexes are, on average, slightly taller. Devon Rexes stand between 10 and 12 inches high at the shoulder, while Cornish Rexes stand 8 to 12 inches high.

Devon Rex vs Cornish Rex: Coat

One thing that both cats are well known for is their unique coat. However, although both cats have short, curly hair, Cornish Rexes have a noticeably finer coat than Devon Rexes.   The breed standard for Devon Rexes states that their hair should have a loose curl, giving the coat a wavy appearance. However, their hair is also quite fragile, which sometimes causes them to be completely hairless in areas where they lick themselves often. It also causes their whiskers to break off – leaving them much shorter than those of Cornish Rexes.

Although Cornish Rexes hair is also curly, it is incredibly fine as it lacks the outer guard hairs – meaning it only consists of the soft undercoat. It often looks softer and shorter than that of Devon Rexes. Additionally, Cornish Rexes often even have curly whiskers!

Possibly the most distinctive difference between Devon and Cornish Rexes is still their appearance. Cornish Rexes have a distinctive egg-shaped head with high cheekbones, and their ears are large and triangular and typically described as “bat-ears.”  Cornish Rexes also have a slim build, long neck, and long back legs.

However, Devon Rexes have a wedge-shaped head which leads to them being described as having an “elfin” appearance. Devon Rexes have large ears which are slightly rounded and set low on their heads. They also have shorter back legs and a more muscular body – particularly around the chest area.

Although both cats are incredibly good-natured and make excellent pets, a few slight differences in their personalities set them apart. Devon Rexes are typically known as class clowns as they are active and energetic. They are intelligent and love to play while being incredibly vocal to ensure they have your attention. One of their favorite games is to hide around corners while meowing until you go to look for them. They also thrive on praise and love nothing more than to sit contentedly purring in return for affection. However, they also like to sit in high places around the house and seek out the warmest spots. Comfort is definitely high on their agenda!

Cornish Rexes are also incredibly playful and intelligent. They are often described as similar to dogs in that they are easy to train and enjoy spending hours playing with and retrieving toys, and this is only one trait that makes them especially good around children. They are active and agile and love to climb – there is virtually no area that is safe from them as they have such an inquisitive nature!
