Former heavyweight champion, Mike Tyson has been known for owning pet tigers. One of them even appeared in The Hangover. However, Mike Tyson has also had a love for pigeons since he was a little boy. He’s said before that without the pigeons, he probably would have never gotten into his first fight. There was a bully who hurt one of his pigeons and he beat up the kid on the spot. Tyson keeps over 1,000 pigeons at home.
