Pandas are bears, but they almost only eat one thing: bamboo. Bamboo is a tall, woody grass that grows in fast green forests. A panda will sit down for hours and munch through bamboo stems like a person chewing celery sticks - except they eat around 12 to 38 kilograms of it every single day.
Bamboo isn't very filling, which is why pandas spend so much of their time eating. To save energy, they don't run around much. They sleep, eat, then sleep again. A wild panda might spend 10 to 16 hours a day just eating.
Baby pandas are tiny when they are born - about the size of a stick of butter. They are pink, almost hairless, and have their eyes closed. The mother is over 800 times bigger than her baby. By six months, the cub looks like a fluffy black-and-white teddy bear.
Pandas almost disappeared from the wild because their forests were being cut down. China protected huge areas of bamboo forest as panda reserves, and now their numbers are slowly going up again. People around the world have helped too, by raising money for panda conservation.
