World’s oldest known pygmy hippo turns 52: ‘Anyone who meets her falls in love’

Hannah Shirley, born in November 1973, was celebrated with Hungry Hungry Hippos-themed party

The San Diego Humane Society's Ramona Wildlife Center is feeling festive, and it has nothing to do with Thanksgiving, but instead a birthday celebration for a hippo that turns 52.

Hannah Shirley, the world's oldest known living pygmy hippopotamus, turned 52 years old on Thursday, and celebrated with a Hungry Hungry Hippos-themed party. Hannah was surrounded by guests as she played with different-colored balls and presents.
