But as they got older, Wang began to notice some unusual qualities in his pets. The "puppies" developed large appetites and started killing Wang's chickens, the Daily Mail reports. Each pet also grew to 100 pounds.
According to the Daily Mail, Wang's stunning realization came after he read a Public Security Bureau pamphlet: His pets were Asian black bears, Category 2 protected endangered animals. Wang handed his pets over to the authorities, who took the animals to the Yunnan Wild Animal Rescue Center. A spokesman for the facility told the Daily Mail that both bears – one male and one female – are healthy and doing well.
