A group of tigers at a Chinese zoo were given a special treat yesterday afternoon, a live donkey. In a video that has gone viral on Chinese social media, a reluctant donkey is seen being pushed out of the back of a truck into a moat surrounding the tiger enclosure inside the Yancheng Wild Animal World in Changzhou, Jiangsu province. Visitors then look on in horror as the tigers swim out and start doing their thing. Though apparently these tigers are bit out of practice. It took them 30 minutes to kill the donkey as it struggled in the water.
