American Society for the Prevention of Cruelty to Animals

Founded in 1866, the American Society for the Prevention of Cruelty to Animals (ASPCA) was the first humane organization established in the Americas, and today has more than one million supporters throughout North America. The ASPCA's mission is to provide effective means for the prevention of cruelty to animals throughout the United States. The ASPCA provides local and national leadership in animal-assisted therapy, animal behavior, animal poison control, anti-cruelty, humane education, legislative services, and shelter outreach. The New York City headquarters houses a full-service, accredited animal hospital, adoption center, and mobile clinic outreach program. The Humane Law Enforcement department enforces New York's animal cruelty laws.
