If you think the mouse squeals you can hear between your walls are gross, just wait until you listen to the ones that are normally (and luckily) inaudible to the human ear.  Sure, over hearing a neighbor or roommate having sex can be quite traumatizing, but male mice screech higher than Michael Jackson when they’re getting tail. Researchers at the University of Toronto, have discovered that boy mice actually have feelings and real emotions—it’s in their genes. For example, when a male mouse encounters a female or even simply smells one, it gets so excited that it will chirp in a special way based on its individual genetic make up.  Basically, male mice sing sweet ballads to show their softer side—remember Fieval from American Tail?
