Most raccoons live in the wild. Being around humans does not bother them. They often nest in empty buildings, garages, sheds, and even the attics of houses. Raccoons do not hibernate in the winter. Those that live further north where it is colder, grow thick coats to keep them warm and spend long periods sleeping. Raccoons that live in captivity can survive up to 20 years. In the wild, they usually live only 1–3 years.
