Well AA I won't give you any advice, you seem to have a handle on things. I just wanted to say that what you have done for the little guy is just perfect, he really does look as if he has been outside for a while. As someone who has taken in his share of strays, dogs, cats, owls, squirrels even, no not at the same time that would be bad, I have to commend you on doing this for the little guy, I hope you decide to keep him, if my experience means anything you will, but then I get attached to animals quickly. Best of luck whatever you decide.
