The animals do not look well cared for, I wonder if the lion has any claws either or surely the horse would be injured each time the lion jumped on?
In any case, I can't imagine what that must be doing to the horse's psyche. That's not entertainment, it's pure cruel IDIOCY.

"I used to look at [my dog] Smokey and think, 'If you were a little smarter you could tell me what you were thinking,' and he'd look at me like he was saying, 'If you were a little smarter, I wouldn't have to.'" - Fred Jungclaus
