Elephants at the Woodland Park Zoo weren't the only ones looking for a change in scenery - a lion cub escaped from its exhibit recently.

The Seattle Times reports that the 6-month-old lion walked out of its exhibit through an open door April 15, the same day handlers moved elephants Bamboo and Chai to the Oklahoma City Zoo, where they'll be able to socialize with a herd.

The cub roamed the service area in the feline building for about an hour before being returned to his exhibit. No visitors or staff were in danger and the keeper who left the gate open was reprimanded, according to a statement from the zoo.

The escape fuels the ongoing legal battle surrounding the elephants. It was used as evidence of a pattern of unsafe handling in a complaint filed Monday by a group that wants Bamboo and Chai moved to a sanctuary instead of another zoo.
