Raccoons make their dens in trees, caves, mines, woodchuck burrows, barns and rain sewers. When they cannot find suitable trees, raccoons may make temporary homes in human houses or empty buildings.
Raccoons prefer to live in moist woodland regions where they have easy access to a reliable water supply, but they can also survive in tropical, farmland and suburban areas. As nocturnal animals, raccoons frequently spend hours resting in their dens in the daytime. Tree dens are also essential for protecting newborn raccoons, which are blind for their first 18 to 24 days, according to Animal Diversity Web. Male and female raccoons may share dens briefly during mating, but in general, mother raccoons live alone with their young.
