FearfulSymmetry: Yep. Mine likes to attack your toes if he happens to see you move them in your sleep.
I had a really scary experience a few months ago. I always sleep on my side, never on my back - I can't even remember the last time I slept on my back. Except for this one time a while ago when I woke up lying on my back. As this never happens, I felt very confused, but when I tried to move my legs I found that I couldn't move them at all. So I panicked, thinking that something had happened, and I'd somehow become paralyzed or something.
Then I discovered that the cat had decided to take advantage of the situation by going to sleep on my upper legs, which was why I couldn't move them. :P I was really scared for a moment there.
