The Opossum Society of the United States was formed by a group of concerned citizens interested in rescuing orphaned and injured opossums. Our network of volunteers rehabilitate opossums for return to the environment. We receive thousands every year from animal shelters, veterinarians and concerned citizens. Other volunteers present educational programs to schools and organizations. We also serve as a valuable reference source for veterinarians, wildlife rehabilitators and the public.
