Ah, so you ignored the "as humans" part. Do animals suffer an the negative emotional experience? I don't know. Do they suffer a negative sensory experience? Perhaps in your rush to prove that you're an idiot, you missed this passage:
"There are two distinct components to pain: the sensory component called "nociception" and the aversive, negative affective state. Nociception allows detection of noxious stimuli and enables a reflex response to move an appendage or whole body away from the source. This capacity is found across all major animal taxa. Nociception can be observed using modern imaging techniques, and a physiological and behavioral response to nociception can be detected but, there is currently no objective measure of suffering."
So, animals do feel pain, we just don't know if it requires them to go to therapy to be able to deal with the overwhelming emotions brought about by their parents not loving them enough.
