Hypoallergenic
Despite some belief to the contrary, the Cornish Rex's short hair does not make it non- or hypo-allergenic. Allergic reactions from cats are not the result of hair length, the true culprit is a glyco-protein known as Fel d1, produced in the sebaceous glands of the skin, saliva, and urine. Most people who have cat allergies are 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. Since Cornish Rex cats groom as much as or even more than ordinary cats, a Cornish Rex cat can still produce a reaction in people who are allergic to cats. However, it is widely reported to cause lesser to little allergic reaction. It is recommended a potential owner visit a cattery to check their own tolerance. Note that, for more serious allergies, there are several breeds theorized to lack or produce less of the offending protein, see allergy to cats.
