The lions in both videos look like they have been raised since they were cubs. You don't form bonds like that with fully grown lions...unless they have been accustomed to human presence since they were newborns or very young. It may look like they are friends and tame, but it is more like they tolerate him and her in some symbiotic relationship where they feed the animals or don't recognize them as a threat or see them as a food source. You can see the guy in the lion kennels after having taking them out to play. But IMO, they are messing with a ticking time bomb. Lions, tigers etc. can be trained but they cannot be domesticated or made "tame". The cheetahs look like they are wild, but most likely live in a preserve. They probably see safari trucks every once in a while, but definitely don't look like they have been cub raised like the lions. I think that chick being raised in "the bush" is probably well versed in animal behavior and knows what the right and wrong things to do in front of certain animals are. I think she was showing how cheetahs will not typically attack anything that is much taller than them (a person standing on 2 legs probably also looks nothing like their 4 legged usual prey), but she plays into their instinct of chasing anything that moves. If you have ever owned a cat, you know that they love to go after anything that moves. They can't help it. If that girl were to trip and fall I'm sure they would be all over her (the Cheetahs)...but I'm sure what we didn't see was the guy with the shotgun standing just out of the camera frame, lol.
