I agree. Some humans have lower cognitive capacity than farm animals, still we wouldn't think it's okay to use mentally challenged humans for food, vivisection, etc. Focusing on cognitive skills to make ethical judgments is incredibly flawed when you think about it for more than 2 minutes. Specially when you add companion animals into the equation, given that pigs seem to have higher cognitive abilities when compared to dogs[1].
