Bringing home animals may be an occupational hazard for the actress and animal advocate (also the daughter of Clint Eastwood), who cohosts National Geographic's Animal Intervention, a new series that takes her to roadside zoos and magic shows where captive animals are living in peril and need rescuing.
In each episode, Eastwood and animal expert Donald Schultz try to convince overwhelmed or incapable owners to relinquish their lions, bears or bobcats to sanctuaries where they'll live fuller lives.
As Eastwood and Schultz cross the country exploring the strange world of exotic animal ownership, they are confronted with the truly bizarre: like Sara Jo, a monkey with breasts like a human, who they meet in the second episode.
"[It was] a Jayne Mansfield-looking monkey," she jokes.
