Aah... memories! Brutus and Litha both used to do that. It was so cute and annoying! In this house, Litha's learned to use my flyscreen as a cat door, so he need never feel trapped.
Once, when Brutus was confined to the bedroom, he was doing laps of the room:
Bed... dresser... dresser... table... TV... floor... bed... bed... dresser... dresser... table... TV... floor... bed... <grab> <stuff under sheets and hug tight> <sleep for another two hours>
