Sadly the Red Panda we saw in that adorable video passed away yesterday. If you don't recall, the abandoned baby was taking up with surrogate mommy – a tabby – after being rejected but her own mother.

It was the first time that a red panda was suckled by a cat within the European breeding program for endangered species, and the lil one was raised along with four kittens born around the same time. Turns out the cub suffocated when her windpipe was filled with milk, but was otherwise in good health. So sad, but kudos to the feline for helping out while she could.
