I don't see how it's possible to know one way or the other whether or not a creature without language (as we know it) feels pain. The only reason I have to think that other humans feel pain is the fact that I feel pain and they tell me they feel pain, and as they're similar to me, I believe them. Maybe just the similarity is enough without them screaming in agony.
