PETA focuses its attention on the four areas in which the largest numbers of animals suffer the most intensely for the longest periods of time: in the food industry, in the clothing trade, in laboratories, and in the entertainment industry. 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. PETA works through public education, cruelty investigations, research, animal rescue, legislation, special events, celebrity involvement, and protest campaigns.
