GEN353 Only man feels shame and embarrassment.  Every animal in the world was born naked and remains naked for its entire life.  It never thinks of itself as naked, and is never clothed (unless it is in a circus or the pet of an overzealous owner).  In a similar manner, all animals feel no shame in relieving themselves in public or in front of other people.  According to the Midrash, the feeling of shame was given by God to man in order to distinguish him from all other creations.  Otzar Hamidrashim, “Ma’sim” 9  AMJV 94
