I've pondered this question for a couple of years, and I think of it whenever we trap one or hear one chewing in the walls. It's not exactly a zoological question, but more of a philosophical question. The house mouse: is it wild, or domestic? In a way it seems wild. Humans do not deliberately feed them, house them, or take care of them. Mice often live in fields and wooded lots, in wastelands and the sites of old buildings. People even have cats for the express purpose of controlling mice. Yet in another way, the house mouse seems domestic. It follows human civilization from continent to continent. It is even found in our houses and barns, manmade buildings. It eats food and garbage that we leave behind, and keeps warm in our heat vents. Its distribution has largely been enabled by humans. But then again, you can't call them domestic like a dog, or a cat, or a sheep. So I've started a poll. What's your verdict on the mouse?
