Yes, I have heard that the Sphynx, which is a hairless cat, can be great for people with allergies. Obviously, it's a little bit of a different look in a cat, but you still get a wonderful feline personality. There is some care that comes along with tending to a Sphynx's skin, but nothing outrageous.
And Sol will probably be able to tell you better, but I've heard that Rex cats (Devon and Cornish), because of their unusual fur texture, do not provoke an allergic reaction in a lot of people.
Of course, these are both purebreeds that you're looking at, so there is some cost that goes along with finding and aquiring one, but it may be worth it for the kitty companionship. Good luck!
