Burrowing, or fossorial, animals live underground and for a variety of reasons. For some it is so they can feed on soil flora and fauna, for others it's to avoid predators or to hide away from the extremes of climate above ground. So, a British mole avoids the worst of the winter cold in its tunnels, whilst a naked mole rat in Africa gets protection from the heat. Both have some protection from roaming predators.
