Even if your allergic to cats, if you were to submit yourself a little at a time to one particular cat you will build up an immunity to that particular cat. I looked into this and proved it by when my stepson moved into my house to live with us. He is highly allergic to cats and is asthmatic, but we slowly had him spend time with the cat before moving in and over about 2 months time he no longer was effected with any sneezing, eye watering or nose stuffiness.
No, sorry I have not ran across a cat that is hypo-allergenic and I LOVE cats but I can't have them because my eye lids swell up where I can't see for like hours so I really can't have them. I suppose the hairless cat should not bother you but you know, eh. Please if you research it and find a breed tell me! here is a link to a site enjoy! http://www.catster.com/cat-breeds/hypoallergenic-cat-breeds
Siamese breeds are hypoallergenic. I'm very allergic also to cats especially Scottish folds! I think they are the worse. But Siamese cats are perfect for people whom are allergic to cats. But take no risks and be sure you give them baths once a month like I did. Otherwise you may have problems.
