Mice are hardy creatures that are found in nearly every country and type of terrain. They can live in forests, grasslands and man made structures easily. Mice typically make a burrow underground if they live out in the wild. Their burrow helps protect them from predators. Their natural predators are cats, birds, wild dogs and foxes.
Mice are nocturnal, meaning they like to sleep during the day. This is why pet mice or house mice can be heard playing or foraging during the night. Most wild mice are timid toward humans and other animals, but they are very social with other mice. Domestic mice are very friendly toward humans and can make good pets for older children and adults.
According to the RSPCA, mice are very territorial. Even domestic mice like to have a large area that they can claim as their own.
