I have a "hypo-allergenic" cat. He is a Devon Rex. They do have fur, but not very much. My sister, who is very allergic, also has one. She is still has some allergy symptoms, but not as severe as with a "normal haired" cat. They are expensive to buy as kittens, but much less expensive if you get a cat instead of a kitten. I bought mine when he was a year old for $200. The breeder had kept him because she thought he would be a good show cat. Luckily for me, his fur was not perfect, making him pet quality and not show quality.
As for the Ashera, it is beautiful! I would love to have a 30 lb. kitty! Every time I go to the zoo I covet an ocicat.
