A Californian mouse eating

California mouse

California mice live in Mexico and, of course, California where they hole up in ready-made burrows. These are no ordinary mice, and once mated a pair will stay together for life, with the males spending a great deal of time in caring and protecting for the young. This large-eared rodent is also an excellent climber and can often be found in the trees of its forest and woodland homes.
