Where's Smokey?

I lost Smokey for a full 30 minutes one day. Thunder crashed in the distance and Smokey fled somewhere into the dark recesses of our apartment. Since he didn't trust me after our visit to the vet, he refused to seek my comfort as usual.

Now, our apartment is not big. It's a 640 sq ft one bedroom abode. Sure, we have nooks and crannies he can crawl into, but he's kind of a big cat and most of our furniture is backed up against the wall. There are only a few spaces he can crawl into where we would not be able to find him easily. (For example, he squeezes into the space under the bookshelf in the picture in the link...it's hard NOT to spot him.) So when I checked his usual hiding place in the closet, I was surprised not to find him. How could I have lost him in the closet again?

Turns out I did not look carefully enough.

"Oh, you found me."
