Here is the little orange fellow who came running up on my porch the other night. Oddly, he has been around for well over a month, and would run away whenever he saw me. The other night, however, he came busting right up the porch stairs as soon as I came out. He was frightened off by Molly's yaps, but came running up again when I put her in the house and came out with a bowl of wet food.
He appears to have a detached right retina. The vet will be able to tell more. He is totally friendly, and is still amazed that he can eat all the food he wants.
