Again, not that it matters but the Cincinnati Zoo is replacing the fence with a 48" high version with rope netting to prevent this from happening again. The Zoo has been open since 1875 and is known for having one of the most active and successful breeding programs for endangered animals. I hope that this never happens again and I hope that zoos across the nation are taking a hard look at their enclosures. You can't totally dummy-proof things but you can make it more difficult for children to get in. Zoo Enclosures should be rated 12 and up. It's why I typically go to the Columbus Zoo instead because I really enjoy the more spread out feel. The Cinci Zoo is bordered by homes and is in the middle of a neighborhood with no real expansion room.
