This is not a new trick, about 2400 years ago in China, a senior offical wanted to know who were on his side, brought a deer in front of the king and said it was a good horse, some of the officals kept silence while the others said that it was a deer, not a horse. King did not know who to trust, eventually more and more said it was a horse. Then the testing offical knew who were his party members and used them to fool the King.
History is repeating 2400 years later. You think it is a mouse or a cat, check it out again!
