Pandas were originally carnivorous animals just like their cousin bear. It is hard for a predator to change from meat eating to feeding on vegetables. However, the giant panda is the only opposite case, and they chose the most difficult thing to digest. High-fiber bamboo is difficult to digest.

New research shows that panda genome is insensitive to the flavor of fresh meat, resulting panda not feeling the love for meat any more. Of course, another reason is that panda living environment has been constantly on the change.

Scientists have discovered in panda's gastric juice samples the existence of a large number of ciliates. Experts say that the ciliate may be effective in help the panda digest bamboo.

Docile and cute, pandas are not predator, but they catch bamboo rats, because they are a threat to panda's staple food bamboo. In order to catch them, pandas show no mercy. Although pandas look clumsy, they are particularly sensitive to any smell. They first smell out bamboo rats' hiding cave, and then firmly blow wind into the cave. Their two front paws at the same time slap the mud surface of the cave. The rats cannot afford the big noise and flee right into panda's hands.

When the rats are caught, panda will play the cat and mouse game. First they play with the rat in their palm or using the other palm to caress the rat. It often scares the rat into fake death, and panda will go away at certain distance. When the rat sneaks out under radar, panda p will quickly come back and capture the rat again. The game will repeat three or five times until the panda gets bored, and then the panda will EAT THE RAT ALIVE FOR GOOD!!!

When pandas drink, they behave like a toddler. They drink a few mouthfuls and leave, walk a few steps and return to the river to drink water again – Back and forth non-stop; but they are also massive drinkers like a drunkard. They drink happily, drink to the belly bulging into a ball, but even so they do not want to leave, often they drink the "hell" out of the water.

Male pandas pee with his body standing upside down and their rear end high up leaning on the tree. This "gymnastics stunt" can help panda's urine reach a higher tree location, thus enabling them to spread their odor, thereby increasing the success rate of their brief mating period.

Panda often takes the trouble to find the thickest trunks possible, ideally long rough bark, which helps the urine penetrate deeper into the trunk, so that the smell can remain longer. And scientists have found that their urine concentration is higher than any other kind of bears.
