Hi Jaz,
They are warm to the touch and do have a higher temperature. They aren't truly hairless though but more like peach fuzz, it feels like you are petting suede. They do appear more dog like and ours has a great temperament. We don't let ours outside, the winters are so cold and the summers so hot. As they do not have fur like a regular cat the oils from the skin tends to build up on the skin and they do need a weekly bath. It is a nasty substance and looks like tar.
