Are you missing a gray long-haired cat? One fitting that description was in the food pan at my house on SE Pounder Rd. It is very thin and it's shoulder's are torn up pretty bad. I don't know if from a fight with other cats (several feral cats live here) or with a raccoon. If you think this may be your kitty, we can try to trap it. Give me a call: 503-695-5640
