Twin Sumatran tigers and two baby orangutans are buddies, sharing a nursery room at the Taman Safari zoo in Bogor, Indonesia.
From the Associated Press:
After being abandoned by their mothers shortly after birth, the four play fight, nipping and teasing each other, and cuddling up for a shared nap when they are worn out."This is unusual and would never happen in the wild," said zoo keeper Sri Suwarni, bottle-feeding a baby chimp on Wednesday. "Like human babies, they only want to play."
