I can just see a bunch of 5 year-olds sitting in a circle at group counseling.
At first I would have thought that as well, but after watching the interactions at the tiger exhibit over the last few years I've noticed something different. At least with the kids who are around 2 to 3 years old or so, they are just fascinated by watching the tigers eat. As they get older, especially into pre-teens and older, and have picked up "sensitivities" from maybe their parents or whoever, then they complain or get grossed-out.
Right after I took that shot above, the tiger took the rabbit into a little cave that has a glass wall on one side. There were a couple of little maybe 2-3 year-old girls just pressed up against that glass watching the tiger, who was maybe 3 feet from them, ripping that rabbit to shreds and eating every bit of it. They were having a great time. Obviously PETA had not gotten to them yet.
