An animal cannot go and look in a mirror and realize that it is a reflection and not just another animal. An animal is not self aware. A robot, given advancement in technology, may not just become self aware but be able surpass its creators in intelligence. Our closest cousin, the chimpanzee, if properly trained and educated, can reach this level but a dog or cat cannot. Then again I do not classify many primates in the same classification as animals due to this.
