I'm sorry, I hope he turns up.

Once, after a day. He was at a nearby cat hangout (an abandoned house). He cut open his paw pretty good and couldn't walk very well. It was one of the first places we looked because we knew he went over there all the time. Some point after we left, he managed to hobble out of where ever hiding spot he was in and then just laid in the yard waiting for us to come back.
