Secrets of the Zoo

An orphaned baby manatee is rescued from the wild, and the zoo staff manages to retrieve an important urine sample from a beloved manatee mom. It's a big new world for the zoo's newest additions — adorable tiger cubs. A male oryx joins a herd of females, while the zoo staff collects lifesaving blood from a giraffe, and has some fun feeding their hyenas.

The zoo doctors go into hero mode, attempting to replace a missing bone in a cheetah's shoulder and rescuing 16 macaws from a hoarding situation. They also perform pregnancy tests on rare mares, give baby polar bear cubs swimming lessons and treat rambunctious — but loveable — flamingos with leg problems.

Young kangaroo Fergus gets a gut check in the love department while Zuri, an expectant warthog, delivers unexpected results. Baby, a beloved black rat snake, develops a concerning mass, while Mac, the zoo's oldest silverback gorilla, gets a surprise birthday party.

At the zoo, 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, a takin has a hitch in his getalong and Jack Hanna causes chaos through the zoo as he prepares to delight a crowd, while 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.
