We owe them [animals] a decent life and a decent death, and their lives should be as low-stress as possible. That's my job. I wish animals could have more than just a low-stress life and a quick, painless death. I wish animals could have a good life, too, with something useful to do. People were animals, too, once, and when we turned into human beings we gave something up. Being close to animals brings some of it back.
