Outside Stray Cats

I live in a trailor park and there are several stray cats around here. I feed them every day and they go out and hunt on their own too. Some of the old neighbors don't care for cats but others are very happy they don't have any mice in their mobile homes like they used to. My next door neighbor said she had mouse droppings everywhere she looked before I moved in 9 years ago. I'm a cat person and have two inside cats of my own. I even cut a square hole in the bottom of my shed door so they could get inside on really cold days.I guess sombody has to do it and God chose me.
