The Chengdu Research Base in China seems like it just might be one of the cutest places on earth – and it’s vitally important for the survival of the endangered giant pandas that we all love so much, too. This panda “daycare” is actually a specialized breeding center and nursery that seeks to breed new pandas to revitalize the dwindling wild population, which may be as small as 1,864.

Each panda cub is special – not just because of how cute they are, but also because of how hard it is 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.
