Be careful! When my cat was a kitten, she would always want to "sleep" under the covers. I say "sleep" because she wouldn't actually sit still much. She'd rub against my hands and demand to be scratched, then when I did scratch her, she'd want to knead my stomach with her paws. It was cute at first, but then she grew up and it got annoying.
We started kicking her out of the room before we went to bed, but she got smart and his under the bed until we turned the lights out. She still tries to weasel her way under the covers.
