The Cornish Rex does not shed like other breeds, their short, fine hair is hard to see, and the best benefit of all is that they don't deposit their hair over the furniture like other animals. Most cats have a three layer coat (outer “guard hair” layer, middle which is the “awn hair” and lower "down hair”). The Cornish Rex is missing both the guard and awn hairs leaving the very soft and silky down hair coat. The coat is very short, lies close to the body and is incredibly soft to the touch and ripples washboard waves or marcel curls. There is much less shedding however that also means the cat feels the cold much more so and it is not suitable for the colder climate of the outdoors.
Cornish Rex are not non-allergenic nor hypo-allergenic but being a low shedding cat makes them much more suitable for people with an allergy. However, some allergic reactions to cats may not be the result of hair length or shedding, sometimes the culprit is a glycoprotein known as Fel d1, produced in the sebaceous glands of the skin, saliva, and urine. People with cat allergies may be reacting to this protein in cat saliva and cat dander: when the cat cleans its fur, the saliva dries and is transformed into dust which people breathe in. Up close and personal exposure to a Cornish Rex is the best way to see if this breed affects your allergies. Regular bathing or wipe down may improve allergy issues and their low maintenance coat requires little grooming but they do love to be brushed with a soft bristled brush.
Cornish Rex cats come in a wide variety of coat colours and patterns, including red, white, blue, black and chocolate, tiger-striped red tabbies, bicolor "tuxedo" coat in many colours, "smoke" colours and the elegant colour-point patterns as in the Siamese breed.
