The Louhe City Zoo in China's central Henan province has an absolutely amazing lion habitat. What's so amazing about it? The lion in it is a dog.
When the original lion was sent to a breeding program (which I assume is probably code for, "We taught the lion to smoke. It was funny but he's dead now"), zoo officials did what any responsible, upstanding institution would do: They replaced the lion with a dog. A Tibetan Mastiff to be precise (pictured below). Then they stood next to the cage avoiding eye contact with guests and whistling conspicuously. The switcheroo was only revealed recently when someone heard the lion bark.
