Uh oh! Cats can be very insistent when they want in and out of any space.
I accidently locked Patrick into "his" room overnight. He has his litter box and food bowl in there and he sleeps on the daybed a lot. So there should not have been a problem but apparently he really wanted out and could not open the door. He scratched so hard on the carpet right there where the door SHOULD open that he ripped it out of the metal part that goes across the edge at the door and destroyed a piece of the carpet about the size of my hand. Oh my, now what? This is a RENTAL! I usually pull the door shut just far enough that it is almost closed to keep the other cats out who are not smart or strong enough to push the door open, and he puts his paws under the door and pulls it open (he's really strong). But this time I had pulled it all the way closed and he could not open it.
If that had been Panthera he would have been banging on the door and making it rattle in the door jamb and also voicing his displeasure of being on the "wrong" side of the door, but Patrick does not do that, he just wants to pull the door open.
Maybe if I hang some bells on the door knob on the inside he would use those intentionally or by accident if I hang them real low so I could hear him?
