The four-striped grass mouse is a small rodent that lives in the southern part of Africa. It has light fur and four dark stripes along its entire back.
The four-striped grass mouse differs from other mice and rats by its bright stripes on the back. It is important for nature as food for snakes, birds, and small predators and helps spread plant seeds.
