Apparently you can tell a lot by a person by the way they treat animals...If the same is true about a city and the way they run their zoo, then I may be going of Beijing.
Granted, most of the place was built in the 50s, but considering the massive investment that I have seen in almost every area of Beijing to ensure it presents a 'modern' face to the world over these few weeks it certainly highlights where the zoo comes in the city government's priorities. But then again, the bureaucrat are not the only issue...
Despite innumerate and prominent 'do not feed the animals' signs (in Chinese and English) at almost open-fenced every exhibit I witnessed either parents or teenage boys (trying to photograph their child or impress their girlfriends) by either taunting the animals or teasing them with nutritious fare like processed cheese sticks. At first I had thought it a shame so many cages were featureless sealed glass and concrete, but at least these creatures were spared the junk food and poking.
Of particularly poor order, and odour (of stale urine ammonia), was the big cat 'enclosure'; a wide range of tigers, a panther, a siberian tiger and a pair of lions were all housed alone and continually pacing up and down their concrete boxes that were barely twice their length square!
Anyway, I have posted a few snapshots here (including, the obligatory Pandas).
