Sealion swallowed rock of a fist size allegedly thrown into his exhibit from adajacent chimps exhibit, now this. This zoo keeping RARE! white tigers rather than some endangered tiger subspecie may be actually a good thing.
I find regular rotating outside exhibits of big cats quite odd.
What is not clear from this version of the story is that they actually are going to keep lion in the infamouse one outise exhibit and the crossroads like path from indoors will stay... for now.
