How have Pandas evolved to support their eating habits

A panda's daily diet consists almost entirely of the leaves, stems and shoots of various bamboo species. Bamboo contains very little nutritional value so pandas must eat 12-38kg every day to meet their energy needs. While they are almost entirely vegetarian, pandas will sometimes hunt for pikas and other small rodents.

Explanation:

While they are almost entirely vegetarian, pandas will sometimes hunt for pikas and other small rodents. In zoos, giant pandas eat bamboo, sugar cane, rice gruel, a special high-fiber biscuit, carrots, apples, and sweet potatoes. However, the giant panda still has the digestive system of a carnivore, as well as carnivore-specific genes, and thus derives little energy and little protein from consumption of bamboo. The limited energy input imposed on it by its diet has affected the panda's behavior.
