Unfortunately that's what happens when you put food out. You might get other critters too. We have one cat, Chinny, we've been feeding, this is the fifth winter. She will not come in. We know another grey tabby Tom comes too, not every night. And we get raccoons and skunks. Once in a while a fox. We have a cat door in the garage and a warm place with heat in there for Chinny Chin Chin and OH has surprised the grey Tom in there too. As long as he doesn't surprise a skunk in there.
