2 Natural Enemies

The giant pandas hold themselves aloof from the world, but in the habitat, there are still some animals that are their enemies, such as the Asian golden cats, the leopards, the jackals, the wolves and the yellowthroated martens, which will mainly attack the baby pandas, the sick ones, the weak ones and the aging ones. Because the young and strong giant pandas still haven't lost the ferocity of their flesh-eating ancestors, they will not be afraid to face the strong ones, and make the enemies be scared. If the giant pandas in the zoo that seem to be docile and naive are provoked, there could be accidents.

The jackals: mainly attack the giant pandas in childhood, the sick ones, the weak ones and the aging ones. The unique hunting skill is to climb onto the back, gouge out the eyes first, then snap at the anus and pull the intestines out, which is called "dig dog".

The leopards: attack the giant pandas in childhood, the aging ones, the sick ones and the weak ones.

The Asian golden cats: often attack the baby giant pandas.
