"Humans make a significant - and deliberate - mistake when they place wild animals in captivity for the visitors' amusement," says Roberts. "And no matter how much money is spent on these artificial exhibits, they are never foolproof and accidents will happen - with painful, if not deadly, consequences."
The zoo suggests that such little traumas are par for the course when it comes to animals learning to suppress their instincts to wander and explore. In fact, keepers described Bao Bao's reaction to the electrified fence as "predictable," explaining that she's "still learning the boundaries of her habitat."
