This Asiatic black bear has what seems like a very cute quirk: he walks on his hind legs like a person! Yes, it is admittedly pretty adorable on the surface — and while he's alright now — the reason he's able to do this is really quite sad.
He was rescued from a bear bile farm, where he was fed just enough to keep him alive. Those holding him captive did this solely to harvest his bile.
Since he was malnourished for most of his life, his body didn't grow to its full potential, so his spine is able to support this upright position.
As the Holiztic Vet says, while this is only an educated guess...it makes sense that he continues to act this way, as the poor guy was stuck in a cage without enough food for most of his life.
Thankfully, he's fed plenty now!
