This commenter, though, is neglecting one thing: That these wild cats are certainly not roaming in the wild as one would hope. They are part of the theme park, and placed in an enclosure, with roads that the bus can drive through.
This theme park isn't the first to put humans in cages so that they can better view captive animals. Another park in New Zealand has a similar exhibit (though without feeding the animals live chickens ... hopefully.)
When covering the Orana Wildlife Park in September, The Dodo asked the experts what they thought about this kind of reversal of who is in a cage: "This appears to present a positive change away from the traditional arrangement of animals in cages being surrounded by visitors," Chris Draper, programs manager at Born Free Foundation, told The Dodo in September about Orana Wildlife Park's Lion Encounter.
"However, is the lion enclosure any bigger or better than in any other zoo or wildlife park? This set-up might improve the view of the cats for the visitors, but the benefits to the lions are unclear. Does this experience turn visitors into passionate conservationists, or is it just a cheap thrill?"
