PHOTOS: Living With Big Cats

The Jouberts made a rule 25 years ago when they started filming African wildlife that they would not interfere with nature. "There's only one time where we will intervene," Beverly says, "[only] if it's a manmade situation. If there's poachers, or if an animal has a bullet in it, or an animal is trapped in a manmade waterhole. But never when it's nature playing out it's game. Never, ever."
