Premature hippo gets bigger bottle

A hippopotamus born premature is well on the way to good health, steadily gaining weight and graduating to a large feeding bottle, according to the Cincinnati Zoo and Botanical Garden.

Fiona, is now 68 pounds, up from her birth weight of 29 pounds. She was born six weeks premature Jan. 24 and has needed around-the-clock care ever since.

"She's got a long way to go before she reaches her adult weight of approximately 3,000 pounds," the zoo said in a statement. "But her care staff loves the progress she's making."
