Zookeepers in the Philippines captured video of a young orangutan bottle-feeding a baby tiger after the two animals were introduced.
The video, posted to YouTube by John Mills, shows the orangutan using a bottle to feed milk to the baby lion at the Davao Crocodile Park.
Zookeepers said they introduced the two animals in the hopes of forming a bond.
The experiment was successful and the orangutan showed nurturing behaviour toward the cub, including bottle feeding.
