I just adopted a blackie, a 3 month old hairless (sphynx) who I named Austin (after Austin Powers). I had 5 other cats at the time and they couldn't care less about him. My oldest just wants to be left alone. There is some hissing, which is perfectly normal, but absolutely not bad!!! Austin backs right down when the other cats hiss or growl, which is good cuz it shows him where he fits in the "food chain".

Give it a try! Ya never know!
