Where's Sammy?

Shortly after moving here and letting the cats outside at night when its warm, I always wondered where Sammy slept. First thing in the morning, I would look on the deck and he wasn't there, and then seconds later he seemed to appear from nowhere. Well, I finally caught a glimpse of him running out from under the grill. But, I never actually saw him sitting under there or on the grill rack.

Well, one day we eventually spied him coming from the tank area. It never once occurred to us that he would sleep there, but he does! He somehow curls up on the tank and cozies up to the grill cover, which keeps him snug. On this day, his tail happened to be hanging out and I quickly took a snapshot of him darting out once I made noise at the door. It usually happens so quick there isn't time for pictures. Crazy cat!
