A Nebraska zoo triggered emergency protocols on Tuesday after a cheetah escaped from its enclosure.
According to a statement from Omaha’s Henry Doorly Zoo and Aquarium, the incident occurred at 3:40 p.m., when the 5-year-old female cheetah named Gretchen was spotted outside her primary enclosure.
The zoo added that the 60-Lb. feline didn’t pose a threat to the public during her escape because she remained “behind the public barrier,” and zoo staff members had eyes on her throughout the entire incident.
In response to Gretchen’s escape, the zoo “immediately activated” its emergency protocols, sealing off zoo entry points, including the park’s main entrance, “to ensure the safety of guests, students, animals, and staff.” Zoo guests and staff members were directed to secure indoor locations, where they stayed until Gretchen returned to her enclosure, per the zoo’s release.

Omaha’s Henry Doorly Zoo and Aquarium said it is investigating how Gretchen got out of her enclosure and added that they would review her area to “ensure best safety practices.”
