The tiger's trail, dubbed Big Cat Crossing, is part of a bigger initiative called Zoo360 that has changed the way humans and animals experience the nation's oldest zoo. There's no question the experience is compelling for the humans. On a recent visit, I watched children drop their lunches in awe of white-faced saki monkeys hanging out in the trees. I witnessed one couple stop midconversation when a gorilla lumbered overhead, and saw more than a few families startled by the appearance of a large cat that seemed eerily close to them. But the bigger impact of Zoo360, says its chief operating officer, Andrew Baker, may be its effort to transform the experience of animals in captivity.
At a time when scientists know more than they ever have before about the inner lives of animals--and when concerns about animal rights loom large--many experts think that zoos need a major overhaul if they're going to last.
