Dave Salmoni bears a more-than-passing resemblance to Timothy Treadwell of 'Grizzly Man' infamy. Salmoni's approach to his subjects is particularly similar: baby-talking to the lions, getting closer than is safe, pseudo-scientific approach to the supposed study he was conducting.
The alleged purpose of his excursion to Africa was to acclimate a dangerous pride of lions to the presence of humans, so the lions could be safely observed by tourists thereby raising revenue for the preserve. I can't see how this so-called captive cat expert can justify yelling "Cut it out!" at every threat by the cats is supposed to positively impress these wild animals.
The only positive in the show was his attempting to play with the cubs but he only demonstrates that even wild youngsters love to play and can be tempted with a ball and string.
No actual naturalist with valid credentials would stoop so low! Avoid!
