Balinese Cats
Bengal Cat
Bengals aren't hairless, and they don't necessarily produce less Fel D1 protein than other breeds, so what makes them hypoallergenic? The answer is in their coats. Bengal cats have uniquely fine pelts that require considerably less maintenance than other breeds. As a result, Bengals don't groom themselves as often or for as long, so their fur contains less allergen-rich saliva. They also don't shed much, or shed far less than other cats, so whatever dander is present in their fur doesn't get spread around as much. (Bengals Illustrated)
Devon Rex Cats
Closely related to Cornish rexes, the Devon Rex has a similar coat, also consisting of soft, fine down hair, and little to no top coat. Also like Cornish rexes, Devon rexes shed very little of their hair, which they have even less of than their Cornish cousins in the first place. (Catster)
Oriental Shorthair Cat
Oriental shorthairs come in more colors and patterns (over 300) than any other cat breed. But no matter the style of "ornamental shorthair" you choose, it will have a very short, fine coat that sheds infrequently. That's why many people with cat allergies report mild or absent reactions with Oriental shorthairs. It's still recommended that this breed be given regular grooming sessions to keep dander to a minimum. (Petfinder)
Cornish Rex Cat
Most cats have three types of fur that make up their coats. The outer layer is called the guard hair; the middle layer is called the awn hair; and the undercoat is called the down hair. Cornish rexes aren't hairless, but they possess only the wonderfully soft "undercoat" of down hair. As a result, they shed less than other breeds, so some people with cat allergies suffer far less, or even not at all, from Cornish rexes.
Siberian Cat
Well known for its long, remarkably shaggy fur, the Siberian is probably not the first breed to come to most people's minds when trying to think of possibly hypoallergenic cat breeds. But like Balinese cats and Russian blues, many Siberians seem to produce less Fel d 1 protein than regular cats. Some allergy sufferers with extreme allergic reactions to cats have reported no symptoms at all even when surrounded by many Siberians. (WebMD)
LaPerm Cat
The most notable feature of a LaPerm cat is its unique, curly coat. It is believed that the nature of this coat is responsible for a reduced allergic reaction for many cat-allergy sufferers, because LaPerm's shed less than most cats, and their curls help keep their dander from spreading around.
