I once had about 10 feral cats, people used to dump them out in the country. I don't really like cats but rather than see them starve I fed them out by my carport so they didn't get close to the house. One day, I accidently ran over one of them, you can't believe how they were looking at me when I got out to see what I had done and all of them left and never came back. So I saved a few bucks on cat food anyway.
