Pain ≠ Intelligence
If a retarded child hit his thumb with a hammer, or Einstein hit his thumb with a hammer, the pain is the same. You know someone is in pain by the way they scream and writhe. The same is true for the pain an animal experiences. It a convenient lie that just because a creature is not intelligent, it cannot feel pain. That is just an excuse for mistreatment. Our nervous systems and chemistry of pain are identical. Think I’m pulling your leg? Read Do Fish Feel Pain? to see what science has to say on the question.
