Do you feed any stray animals?

I feed a stray cat that's in my neighborhood and there's my neighbor's cat that I think is wayyyyy too skinny (she has 4 dogs and prefers her dogs over her cats - the cats are really her daughters, but the daughter moved and didn't take the them) so I make sure to feed him everynight and give him attention. He's gone a bit ferrel, so occasionally he'll nip at me and stuff, but otherwise, he's so sweet. And SO beautiful. If I could I'd take him as my own, but I'm afraid of what he'd do to my other cats.
