Ah, no! This is an interesting thing about house mice -- they're a commensal species with humans that sort of domesticated themselves. (Though not to the degree that cats did.) House mice really are dependent on human structures for protection, on human food and grain storage, and all that; you can track the beginnings of agriculture moving west through Europe better by looking for the first signs of house mice than by looking for the first grain storage or plowing tools or whatever. Which is ... kind of cool, but also makes them pretty much just a pest!
