This photo is taken in 2011. To be honest, even many of us who always pay close attention to Beijing Zoo didn't know they had kept this species until we saw this photo.
We saw the cage just near the nocturnal house and hog badger when we were there last year but despite many visits back never saw them
when I was there the hog badgers were in the last on the fox runs (behind the nocturnal house of horrors).
In fact I also don't know what happened on them now...... I don't think skunk is a difficult species as they are kept as pets in USA. The place of skunks' exhibit was changed frequently, every year I saw them in a different location, the last time I saw them just next to the entrance of the Nocturnal House and next to the corsac foxes.
The stripes on those skunks are yellow in colour, in skunks this indicates certain things are missing in their diet.. it's not a good sign. I have three skunks in my own collection, they're not the easiest of species to keep but not the most difficult either.
