How might one go about to prove that?
Given that we are mammals, the less extravagant assumption is that the quality of consciousness experienced by other mammals would be substantially similar to our own. So barring any conclusive evidence on either side that would be the more reasonable assumption.
Of course, it is likely that no other mammal or bird engages in discursive thought using symbolic language. Then again it isn't entirely clear whether that is an advantage or loss for us. Probably it is both.
