Who hunts the pandas?

The average adult Giant Panda doesn't have to worry about many predators, they are good climbers, and Excellent swimmers, with very sensitive hearing even at long distances. These abilities combined with their size give them good advantages, and most only worry about the occasional leopard attack. The mother Giant Panda would be on the alert for any sounds, and extra cautious, due to the helpless nature of her cub. The cubs, or young have more to fear from wild dogs and leopards both, but there are cases of the Mother Giant Panda using size, and intimidation to shield their young from attack.

Giant Pandas have very few predators. Humans are their primary predators, though animals such as leopards are also predators mostly of cubs. The largest threat to them though is not predators, but habitat loss.
