Red pandas may look like terrestrial animals like raccoons, but they're arborial--they're awkward and clumsy on the ground, which is super cute, but misleading. They're designed for life in the trees, with super-sharp claws for climbing. The Association of Zoos and Aquariums notes that, to prevent depression, red pandas have to be given items to climb on. "Provide climbing apparatus for older animals," it reads, "but beware: red pandas are escape artists." They might not be great jumpers, but that's about their only weakness as far as escaping goes; they're excellent swimmers as well as climbers. That plus an energetic, curious, and playful personality and metabolism makes them one of the best and most frequent jailbreakers at the zoo.
