Secrets of the Zoo

Tiger cubs take on new turf; an orphaned baby Manatee is rescued from the wild; and a male Oryx makes his move on a herd of females.

Zoo docs rush to save a Cheetah with an orthopedic problem; rescued macaws get new lives; and baby polar bears go off the deep end for swimming lessons.

Keepers try making a love match between young male Kangaroo Fergus and older female Beatrice; Warthog Zuri gives birth; 34th b-day for silverback Gorilla Mac.

A white rhino ultrasound shows surprising results, and a sick guinea fowl becomes an emergency. From Florida to California, the zoo team hits the coasts, returning two rescued manatees to their native waters, and transporting four wild cats to Los Angeles for an appearance on "The Late, Late Show With James Corden."

Baby fever spreads through the zoo as a cheetah repopulation program goes into full effect, and Jack Hanna chases chaos through the zoo as he prepares to delight a crowd. Meanwhile, the park's most chill residents get a frozen spaghetti seal treat.

The keepers make their morning breakfast rounds at the Heart of Africa exhibit, a young bull elephant has a play date while his expectant mother gets an ultrasound, a rare okapi gets a checkup, a cougar has a concerning abscess and it's a winter herd roundup at The Wilds.
