A rhino exhibit at a zoo in Florida is under scrutiny after a little girl stumbled through bars, coming into contact with one of the animals. The 2-year-girl was taking part in an interactive program called the "Rhino Encounter" at the Brevard Zoo in Melbourne. The program allows visitors to interact with the rhinos through a fence that features steel bars spread 11 inches apart. The little girl fell through the bars, touching one of the rhinos. Her father was able to pull her back to safety.
