Mice are the smallest animals in the game. Despite being famous for their fast reproduction it appears the mice in the game never feel the need to breed. They share burrows with rabbits and feed mainly on pine cones and clover.
They eat many different plants and nuts and are not very picky. Clover and pine cones are among their favourite.
Mice will dig their own burrows but they'd prefer to move in with the local rabbit population. The rabbits have keen eyesight for spotting predators and their burrows are often located close to carrot and clover patches meaning that the mice shall never wander far from the warren unless they have an urge for pine cones.
