AWI and SAPL have worked for the successful adoption of more than 15 federal laws, including the Animal Welfare Act, the Endangered Species Act, the Humane Slaughter Act and the Marine Mammal Protection Act. AWI continues to defend existing laws, oppose bills that they believe threaten animals, and work for new protective measures, following through after they are enacted to ensure sound regulation and sufficient funds for enforcement. Current efforts include pushing for the passage of bills to ban horse slaughter, end the sale of random source dogs and cats by dealers and prohibit the use of the steel-jaw leghold trap.
