In North America there have been at least two mall zoos that I'm aware of.
The once (and still?) largest mall in the world in Edmonton, Canada had a zoo in the 1980s with big cats and monkeys I think. Maybe snowleopard visited it in his youth? This mall also once had bottlenose dolphins and an aquarium with penguins and sea turtles.
There was a zoo in the mall in Ontario, California that focused on native California species. I never visited it before it went under, but it had harbor seals, bobcats, armadillos, and several other native species. When it closed down most of the animals went to the Orange County Zoo in Irvine.
