A horrifying video shows Chinese zoo keepers pushing a helpless donkey into the moat of a tiger enclosure. The terrified animal can be seen clinging on as workers push it down a ramp and off a steep ledge into a tiger compound. According to Chinese media reports, a zoo official said that the incident was the result of an internal dispute with a shareholder, who was stopped from selling off some animals, including the donkey, so fed it to the tigers instead. The zoo said that the incident is currently under investigation.
