The American Society for the Prevention of Cruelty to Animals (ASPCA) was founded in 1866 in New York by Henry Bergh and was the first animal welfare organization in North America. It operates animal shelters, provides veterinary services and animal behavior resources, conducts animal cruelty investigations, and engages in legislative advocacy to prevent animal cruelty. The ASPCA has various programs like adoption centers, a mobile adoption unit, disaster response, and a poison control center that aim to promote the humane treatment of animals and reduce animal suffering.
