These polar bear cubs, born and raised at Tianjin Haichang Polar Ocean Park in China, were so tiny and frail at birth that they weren’t expected to survive. Keepers whisked them into an incubator, and have been caring for them around the clock since then. But at 100 days old, the babies are now healthy and playful and super, SUPER cute.
It looks like hand-rearing them has gotten a little more challenging, though.
