Pashmak, a Stray Cat

I have been feeding a stray male Persian cat since he was about 1 month. I can't let him in, because I have already two cats, and I can't take a responsibility for another one.
Today he came to eat as usual, and as soon as I saw him I felt guilty :( He couldn't put his hand down, he was badly injured, the skin of his hand was gone (? I don't know what verb should I use here ), and he wasn't able to walk. Maybe he had been stuck in a trap, I don't know ... Watching him limping with difficulty has been made me feel bad, I have no idea what should I do about him :((
My husband's going to take him to a vet, but it doesn't solve anything. He needs a home.
