I've only just come across it, actually through my Sky news website when I was searching for something. So I took to Youtube to find more on this guy, Kevin Richardson. Thought I'd share in case you haven't seen it. I found this video... Part 2, 3 and 4 are on Youtube. He's been doing this for years it seems but I've never seen anything like it. I must say I am blown away. I mean I can understand a gaining of trust for a wild animal, but for how long? Because we cannot forget, these lions and these hyenas are wild predators that their wild instinct can take over at any time and rip this man to shreds, it's in their nature and if they are hungry or feel threatened, they could easily do it. So this has actually blown me away. There's more of his different documentaries floating about as well if you're intrigued.
