Found Female Cat – Grey Tabby with White Shorthair

This kitty has been sleeping on my porch for the past few nights. This is a very young cat and is VERY friendly, the problem is the cat is terribly skinny and I think it does not no how to survive outside as it was an indoor cat. I really want to find the owner for this sweet little guy. Also, the cat has quite the vocals and isn't found of my other cats.
