The Chengdu Research Base in China might be the only place in the world overflowing with cuteness. Home to the endangered giant pandas that we all love, this center is crucial for the survival of this species.

This panda “daycare” is a dedicated center specialized for breeding and nursery care of baby pandas to revitalize the sharpy declining wild population. It is estimated that there may be only 1,864 pandas on left in the wild.

While all panda cubs almost resemble each other and are very cute, each cub is special mainly because it is hard to get pandas to breed. Females are able to breed for only 2-3 days a year, and they only give birth to one cub every two years.
