CINCINNATI, Ohio -- An adorable baby hippo born prematurely at the Cincinnati Zoo is growing so fast.
Fiona looks tiny for a hippo but she's actually 73 pounds, up from the 29 pounds at her birth.
She's getting a little too heavy for her care staff to lift in and out of the pool, so the staff installed a ramp so she can do it herself.
The zoo says Fiona really enjoys swimming. It's one of her favorite activities where she gets to be independent. null
