Man Scales Fence Into Big Cat Country at Saint Louis Zoo, Climbs Down Before Guards Arrive

A man climbed over a fence into the Saint Louis Zoo's Big Cat Country habitat Saturday evening, sitting on an artificial rock barrier above the enclosure before climbing back down to the public path on his own, before security staff ever reached him. No person and no animal was hurt in the encounter, according to the zoo.

The incident happened near 5 p.m. Saturday, when a zoo spokesperson said the man climbed over the fence and sat above the habitat, according to First Alert 4. Zoo security arrived within minutes, but by then the man had already climbed back down to the public walkway on his own, according to KSDK. Security staff took him into custody and turned him over to police, First Alert 4 reported.

Zoo officials said the man never came into contact with any of the animals inside the habitat. Wild animals can become territorial or frightened in scenarios like this, the zoo noted, and officials stressed that entering or attempting to contact animals inside their habitats is unsafe for anyone.

A High-Stakes Habitat for Rare Cats

Big Cat Country currently houses 12 big cats across six species, including African lions, Amur tigers, jaguars, Amur leopards, snow leopards, and pumas, per the Saint Louis Zoo. Several of those species, including the Amur leopard, are critically endangered. The habitat was also the site of a milestone for the zoo's conservation work: in November 2023, three critically endangered Amur tiger cubs were born there, marking the zoo's first successful tiger births in over a decade.

The exhibit itself dates back to 1976, when it replaced the zoo's old concrete lion house, according to the St. Louis Historic Preservation office. Its design was considered progressive for its time, swapping barred cages for open-air yards separated from visitors by moats rather than iron bars. That naturalistic approach, nearly five decades old, is now part of what the zoo is examining as it reviews Saturday's breach.

Legal Stakes and a Pattern of Perimeter Concerns

Under Missouri Revised Statutes § 569.140, knowingly entering or remaining unlawfully on posted or restricted property is first-degree trespassing, a Class E felony punishable by up to four years in prison, according to Justia. Separately, Missouri law under § 578.608 permits law enforcement or individuals to kill a large carnivore if it is observed or believed to be attacking or injuring a person, even inside its own enclosure, underscoring the life-or-death stakes when a human breaches a predator habitat.

This is not the first time the zoo has faced scrutiny over its perimeter security. In February 2023, a four-year-old Andean bear named Ben escaped his outdoor enclosure twice, an episode that made national headlines and eventually led the zoo to transfer him to a Texas facility with a moat-based containment system, as reported by KSDK. Decades earlier, in March 1989, a pack of wild dogs breached a perimeter fence from surrounding Forest Park, causing seven springbok antelopes to die of panic inside their enclosure.

Zoo Reviewing Habitat, Public Urged to Report Concerns

The Saint Louis Zoo said it is now evaluating whether modifications to Big Cat Country are needed to prevent similar incidents going forward. The zoo has not detailed what changes, if any, are under consideration, and it remains unclear what criminal charges, if any, the man may face from police.

The zoo, which is free to the public and draws roughly 3 million visitors a year as an AZA-accredited institution, maintains two direct lines for reporting security or animal welfare concerns: 314-781-0900 for Zoo Security, and 314-646-5463 for the Animal Care hotline. Officials say prompt guest alerts helped enable security's rapid response to Saturday's breach.
