People like me, people who believe in animal rights, feel the same way about eagles and elephants, pigs and porpoises, as most people feel about cats and dogs. Don't get me wrong. Animal Rights Advocates (ARAs) don't want pigs sleeping in our beds or elephants riding in our cars. We don't want to make pets of these animals. What we want is something simpler: we just want people to stop doing terrible things to them.
