My girlfriend and I got a kitten a few months ago and once we had him for a few weeks he started going missing every now and then. We'd run around the apartment checking ever nook and cranny and then he'd eventually just show up without us ever finding out where he'd been. After one of these incidents we were standing in our kitchen discussing where he could be going off to, and during this time he was sitting in an empty spot where a drawer was supposed to be.
Then bottom kitchen drawer had been broken for some time and the super had recently removed it for repair. Our kitten liked to hang out in the hole where the drawer was supposed to be, but we always checked that spot when he went missing and it's not like he could go anywhere from there.
Well sure enough while we were talking in the kitchen he had just vanished again. We were both so confused as we had swornnhe was right in the kitchen with us in that hole. Realizing he must be somewhwre in the space, I opened a drawer above and sure enough he was chilling with our sandwich bags two drawers higher than the hole. He had been climbing up the back of the drawers like a damn ladder! This guy is a whacko!
