Lost Pet: Oliver

Circumstances

Oliver goes out during the day to play in the yard and woods adjacent to our house. At night, he did not show back up for supper, but he sometimes misses evening meal, so we did not think anything of it. The next morning, he was not at the garage for morning meal, and again, not that night. He has gone for an evening, or a day, before, but never 2 days in a row. It is now the 3rd day, and I am extremely worried he has been taken, wandered off, or worse :-(
