Tatiana and Tonghua, Siberian tigers, are introduced to each other for the first time. Tatiana has never been introduced to a male before. Simon is a tamandua, a South American anteater. He's being moved into a new home because he wrecked the last pen he was in. Patsy is the matriarch of the zoo's African elephant herd. Lately she's been acting out of sorts. Today Barb Luciano, the young elephant keeper, has to get the crafty old matriarch to sit still for a blood test that could help the zoo figure out why she's not been herself.
