A Chinese zoo is facing some backlash today after some visitors noticed that a “lion” was barking.

The Henan Zoo in the People’s Park of Luohe had placed a large Tibetan mastiff–a breed which has a fluffy mane around its head–inside the lion’s cage without an explanation. Now, paying visitors say they feel ripped off.

“The zoo is absolutely cheating us,” said one guest, who was charged 15 yuan ($2.45) for the ticket. “They are trying to disguise the dogs as lions.”

Zoo officials said that the dog belonged to an employee and had been put in the cage for “safety reasons” while the lion was at another zoo to breed. However, further inspection at the zoo led to the discovery of a cage advertising leopards which actually contained a white fox, a snake cage which actually contained coypu rats, and a wolf cage which contained another dog.

While some have speculated that the faux wild animals will actually drive traffic into the zoo, officials say the will correct the signage promptly.
