I’d say that if qualia actually exist in some sense, and animals (at least those that are somewhat related to humans, e.g. mice and other mammals) have qualia, then awareness of pain is most likely among them. I’d also assume that all animals with qualia have some assessment of “pleasing” and “suffering”, because conscious awareness would not be evolutionarily useful otherwise. Craig is probably assuming that animals do not have qualia, although he does not state this assumption clearly.
