@SivatheriumGuy Haha! @twilighter and I actually asked the Curator that question, as we had a partially guided tour of Songkhla Zoo that included off-show Flat-headed Cat, tortoise and civet breeding centers. I'm not quite sure why they have Schomburgk's Deer on the sign.
@Zhao yun Prior to the trip, there was a lot of email correspondence with the zoo and eventually they allowed my friend and I to see the behind the scenes area.
