The House Mouse Mus musculus is a rodent that belongs to one of numerous species of the small mammal. It is found in almost any environment across all continents except Antarctica, and can be viewed as a pest of vermin, as it eats crops and food intended for people!
They have very poor eyesight, but make up for it with their keen hearing and extremely sensitive nose.
They make very good pets, as they are friendly and easily get used to being handled. They are also very clean, and never need to be washed by their owners.
