writes "Caught on an infra-red camera, this panda eating an antelope is a rare sight, as panda stomachs have evolved to digest the complex cellulose found in bamboo stalks. However nature, ever red in tooth and claw, means that if pandas are hungry, they will eat meat. It's unlikely that the panda stalked and killed his antelope snack though. In May, a panda was caught killing and eating a peacock at a zoo in China.
Although a panda's diet is 99% bamboo, they do belong to the species group Carnivora, or carnivores. They have to eat vast quantities of the hollow plant to gain enough energy and nutrition to survive. Panda behaviour has evolved to cope with their weak bamboo diet, which is why they often appear to be slow, lumbering beasts."Link to Original Source
