When Storm was still an only cat, he got locked in my bedroom for probably most of the day. I got home late and heard this loud meowing and banging noise. I use a door stop to keep my door open and he must have knocked it loose and then the door shut behind him. My roommate at the time thought that I wanted him locked up in my room so even though she heard his cries she didn't do anything. Pepper got locked in my roommates bathroom a couple of times. He wasn't in there very long though because I heard him meowing. Sunny got locked in my roommates bedroom. He must have been in there for a couple of hours before I heard him yowling.
