Moosmom, I have 2 Cornish Rex boys, and have noticed how much they are heat seekers. I even have a heating pad with a thick place mat over it that operates 24/7 in the cold months. I've often thought I'd love to get a Sphynx (Buddy is close, as he gets even more naked in the summer and have noticed what must be that oily residue you talk about on his belly and inside of his back legs), but I've wondered if I would be able to keep a Sphynx warm enough. Does that ever worry you? How do you handle it? Turning the heat way up is not an option--beside the cost, I don't like it too warm in the winter.
