Why do we as humans have to wipe our asses, but other animals don't? If you or me don't wipe our ass after taking a crap, we will be in burning misery for the rest of the day, but a dog, cat, or bird can shit at any given time without needing to wipe. How is this possible? I realize they physically can't wipe their ass, but are animals just living in pain after crapping. Someone shed some light on this subject.
