I had similar thoughts when I visited a couple of years ago. The enclosures were all fine, though not especially spacious in all cases (and we visited on a hot day so the indoor area for the Pygmy hippo stank to high heaven!) The lady letting us all in for the show was very snotty when we asked to be on the end of a row - partly because I physically would not have fitted further along and also because I would have had a major panic attack if I had been sitting somewhere I couldn't get out from, so I am sure they would not have wanted that. The man with the stick in with the lions used a large feather instead of the stick at one point to prove it wasn't fear of the stick making the lions do things. I understand that due to the nature of the media work they do, this sort of training with the animals is inevitable (and hey, no one forced me in to watch it), but it did make me feel somewhat uncomfortable. The animals certainly didn't appear uncared for or distressed, but I guess I am just not a fan of that kind of show.
