Well, my girlfriend is interested in taking him, but the guy is afraid of coming inside the house. He does seem to get a little bit more comfortable with being indoors each time he visits, especially if food is offered, though.

However, the case may be that he's never lived indoors and will never be, so she may have to just be content with feeding him, and if we can get him to trust us enough, one day getting him to the vet.
