This Is the Fallacy....
....Of such "wild animal" shows. You are putting a predatory animal into an unnatural enviroment, and training/coercing/encouraging/whatever it to do things it doesn't normally do, for the entertainment of humans. Since the animal is doing things it would not normally do, there will be "accidents" and problems from time to time. Once an incident has occurred, it is not humane or just to kill the animal (though that sometimes happens), but the animal is left with the knowledge that its captors are vulnerable. It's also not feasible to return the animal to the wild in most instances, because its captivity has deprived it of some of its coping skills and blunted its instincts.
The solution, of course, is to leave wild animals in the wild, and to conserve their wilderness so that they'll be able to fend for themselves. This seems never to occur to opportunistic humans wanting to make a buck.
One of the very few people who understands the problem is actress Tippi Hedren, who starred in Alfred Hitchcock's The Birds. She operates a nature preserve called Shambala, which is dedicated to protecting big cats who have been discarded from circuses, badly run "nature" attractions, and even by pet owners. Hedren aims to give them as natural an environment as possible, while still recognising that these animals would no longer fare well in the wild. There are no shows at Shambala, no performances, and tours are very limited; you cannot get close to the animals. Basically, Shambala is set up so the big cats can be big cats again, instead of performers or pets.
I have long refused to patronise zoos, circuses and other "attractions" that enslave animals who would be much happier in their own, natural environments. A certain, very few, species of animal have become thoroughly domesticated (like cats and dogs), and those are the ones to have as friends. You will never truly make friends with a tiger or an ocelot or a killer whale; they are not cut out for it, no matter how much you "train" them. Sooner or later, their instincts and wild nature will re-surface. Even Roy Horn of Siegfried & Roy learned that one the hard way.
