I immediately went to the PhinneyWood blog, clicked under "Lost Pets" and a description of that very cat, a Siamese named Zuul, was the first listed. He had been missing for almost a week and his people were just 2 blocks away. It seemed as though he were an indoor cat who had ventured too far from home to be able to return safely. I immediately called the number, then emailed as a backup.
Later in the day, while at clinical, I received a very appreciative message from his person saying he was coming over for Zuul, then later received an email saying he was safe at home, enjoying his second dinner.
It was so heartening to experience this kitty-person reunion, since Rich and I had decided that every time we saw a "Lost Kitty" sign in the neighborhood, it was really a kitty obituary. No, not true, kitties do turn up once in a while, in the most unlikely of places.
