Here's hoping that he is a loved kitty with a home who maybe decided to "make a break for it" for fun, as some cats tend to do, but this one maybe just couldn't find his way home. I hope he has a good home, perhaps you should put up flyers. My nephew when he was younger had a habit of letting the cats out because he thought they wanted to go out, forgetting his parents said the kitties were NOT to go out. Thankfully, they always came back okay, but it did result in one litter of kittens when the cat in question's appointment to be spayed was all set up, but he decided "Kitty wants out!" Sigh. (Don't worry, the kittens all got good homes, kitty got spayed, and my nephew got older and a bit wiser!)
