On another note regarding kiang's reply, it is surprisingly hard for Singapore to get animals from Malaysian zoos. Ego and politics easily get into the way.
That doesn't surprise me... By the way, I've seen some very nice collections in malayan zoos such as Storm's storks, flat-headed cats, lots of civet species, sumatran serows... really interesting despite the fact that most zoos have old enclosures, most of the time not quite suitable...
Thanks for your answer, zooish.
