The meerkats at Taronga are some of the most entertaining inmates.
They always look like they're enjoying themselves digging holes and keeping watch. Or maybe they're trying to dig their way out of the zoo and the watchmen are keeping an eye out for the keepers.
In fact, maybe Taronga zoo is the meerkat equivalent of Colditz. Or a furry version of Hogan's Heroes if you prefer a humourous prisoner of war analogy.
