This is my friend, the Mystery Porch Cat. There are two such cats, actually, but this one has become my friend and likes to pose for pictures.
He comes by every evening for supper and purrs. It took several months to win his trust, but now he's willing to sit in my lap and lets me pick him up. I'll be taking him in to the vet's soon, to be neutered, tested for illnesses, etc., and then I'll have to try and win his trust all over again. Cats never get that this is for their good, and I'm pretty sure I would feel the same.
