I actually have my cat (here at my parents house) trained (from kitten-hood) to sleep on a blankie at the end of my bed. Thing is, she only usually sleeps on my bed if my parents aren't in their bed, and she chucks a fit if the blankie has moved or been kicked off during the night when she decides to sleep there. You get her all "meow" *pounce* "purr" and she gets in your way as you're trying to retrieve the blankie and spread it out. It's so like that cat.

It's mum she usually attacks in bed if she wants something like food. lol
