Alligator at Beijing Zoo.

Back in 1998, I visited a Chinese zoo in Chengdu. It gave me nightmares for weeks. Elephants and big cats were rocking back in forth in their barren concrete enclosures, clearly suffering from "zoochosis". Monkeys sat in rotting metal cages, scratching themselves and masturbating until their skin was raw. Chinese visitors spat at the animals and threw packaged junk food into cages. Meanwhile, in the reptile exhibit, it was obvious that many animals were long dead. Their carcasses were already furry with mold.
