The animals and bugs on "i'm a celebrity"...?

so, i was wondering about the animals and bugs on "i'm a celebrity, get me out of here!" the episode with the water boarding type thingy where they dumped all of those spiders and snakes and things together, isn't that kind of cruel? and the water tank with the alligators, that's kind of cruel, too. i mean, don't you think that some of these creatures are just as scared? i also feel bad for the live stick bugs that they eat. maybe i'm just too compionate but some of that stuff just doesn't seem right. and, i'm also wondering, who do you think cleans up all of those animals? i wouldn't think they could just let them all loose in the wild because it's not really their natural habitat. just wondered what everyone else was thinking.
