National Council on Pet Population Study and Policy.
Description: "The National Council consists of humane organizations, breeder groups, and veterinary associations brought together to work on mutual goals regarding the pet animal surplus. The Council has conducted studies regarding animal entry and exit numbers from shelters nationally and the characteristics of animals and humans involved in relinquishment of animals to shelters. A national household survey served as a control group for the relinquishment study to help indicate which characteristics of animals and humans were really significant risk factors for failed human/animal relationships. These studies have resulted in publications in peer-reviewed journals. The significance of these publications is their effect of legitimizing the field of pet population research, and therefore encouraging other scientists to address this issue in their work."
