Number 5 – Robert Downey Jr.
Known to many as Tony Stark in the movie Iron Man, Robert Downey Jr. didn’t want cats. He told Men’s Health, “I don’t want any rescue pets within 100 yards of either of my residences, I’m sorry”. But when one of his friends found some stray kittens in a bush, Robert sprang into action like a true superhero and rescued two kittens – they are named Montgomery and Dartanian.
