"If it hadn't been for Hollywood, I'd have fulfilled my other childhood dream -- to be a zookeeper," says Betty White when speaking about her love for animals. We take a rare look into one of White's true passions -- big cats! Head with her to the Los Angeles and San Diego zoos to get up close to big cats. White weaves her natural wit as we look at the cats' individual behavioral traits and learn where they live, how many are left in the wild and the challenges they face.
