Oh my god. That poor old guy! I was sitting here, reading your post, looking at his pics, and was just gasping out loud. I cannot believe how skinny and sickly he looks. That poor, poor thing!!

You are wonderful for what you are doing to help him. I hope that he can get to a vet and get a checkup and some treatment.

Gentle pets to Scrawny, and hope that he will get to feeling much better.
