My youngest cat, Lily, likes to hide in my closet on top of my shoe rack, and sleep on my shoes. The first time she did this she scared me silly. Now I'm used to it, but it drives me nuts because I'm always finding her fur all over my shoes. We also sometimes hear her crying in the hall closet where she'll get stuck inside when someone leaves it open a smidge and another will go by and close it. She'll sneak in when its open and hide on top of the towels or blankets in there. I get scared she'll do this when we'll be out for a few hours. So far we've been lucky she hasn't.
