Adventures in Linguistics

Acdording to an exhibit at the Duluth Zoo, there is actually a thing called the "House Mouse." They are noticeably smaller than the fancy mice sold as pets at PetCo and PetSmart. The ones in the exhibit were actually tiny, only about an inch long.

So, if there is, in fact, a subspecies called the "House Mouse," what do you call them when they are in your house and you have many of them?

"Hice Mice?"
