My cat Spooky (RIP) used to seek refuge in my room. When the kittens (Eddie, Ritchie and Molly) were tiny she made their lives hell, and I warned her that once they grew up the boot would be on the other paw! As it turned out to be. So when I'd come home from work she'd be at my bedroom door, waiting to be let in.
I used to let her sleep with me, and she'd often in the night end up sitting on my head. Sounds funny, but her soft purring used to be very calming.
That is, till the night she couldn't get out and ended up crapping on my head! Needless to say, that was the end of her overnight stays in my room!
I still miss her like hell though.
