All these kitties that use handles to open doors-my boys are far too lazy for that and prefer to keep their bum planted on the floor and use their paws/nails to stick between door and frame and try and pull it open that way
works great on our kitchen door because it doesnt close properly anyway, but AJ is a determined little thing and sometimes when he is closed in the bedroom(thats where he gets fed his prescription diet) and he wants out he sits and does this until a)we let him out or b)he lets himself out
Cats are too clever for their own good!
