Officials believe P-22, a wild mountain lion that prowls Griffith Park in Los Angeles, made a meal of a koala found mauled to death at the LA Zoo.
John Lewis, the zoo's director, said this week that workers found the koala's body outside its pen March 3.
The big, 7-year-old male cougar cat was spotted on zoo surveillance video from the same night.
Zoo workers are now taking extra precautions, like locking up smaller animals in barns at night.
Lewis says the zoo will learn to adapt to the wild cougar, just like it has learned to adapt to the zoo.
P-22 wears a tracking collar and was famously photographed near the Hollywood sign for National Geographic.
Griffith Park sprawls over 4,355 acres of rugged wilderness surrounded by urban sprawl.
