And therefore, even though animals are in pain, they aren't aware of it. They don't have this third order pain awareness. They are not aware of pain, and therefore they do not suffer as human beings do. Now, this is a tremendous comfort to those of us who are animal lovers, like myself, or to pet owners. Even though your dog or your cat may be in pain, it isn't really aware of being in pain, and therefore it doesn't suffer as you would when you are in pain.
