People for the Ethical Treatment of Animals (PETA) is the largest animal rights organization in the world, with more than 5 million members and supporters.

We also work on a variety of other issues, including the cruel killing of rodents, birds, and other animals who are often considered “pests” as well as cruelty to domesticated animals.
