Fiona the preemie hippo celebrates 3-month-birthday

- Fiona, the adorable hippo that was born prematurely at the Cincinnati Zoo And Botanical Gardens, turns three-months-old today.

The zoo celebrated by sharing "day in the life" videos of Fiona on its Instagram and Snapchat accounts.

Fiona was born six weeks early in January at just 29 pounds. The average birth weight for hippos is 55-110 pounds, and Fiona also couldn't walk.
