At World Animal Net, we define sentience in our forthcoming Model Animal Welfare Act as the capacity to perceive or feel things--more specifically, sentient beings share with us consciousness, feelings, emotions, perceptions – and the ability to experience pain, suffering, fear, distress and states of well-being. Animal sentience is a major underpinning for nearly all the philosophies that explain why animals and their interests deserve consideration and flies in the face of traditional Western views of animals as “automatons” who feel no pain and do not suffer, and consequently are “things” that humans can do with as they like. While animal advocates have long been criticized for their views as being based in passion and not rationality, science is now confirming what advocates have always known.
