As tragic as may be, fact is, Humans are quite stupid when it comes to self-preservation, animals don't have to worry about leaving the TV or their iPhone etc. and going back to get it or even staying with it... Animal survival instincts over-ride everything else whereas Humans can be quite the opposite, I remember watching the flooding in Pakistan and some guy completely refused to leave because the rescuers would not take his Cow, his Cow would never have fitted on the small inflatable anyway but the guy refused to leave, he probably died, along with his precious Cow.
