The attack is raising questions at zoos across america - including right here in Evansville. Just like many of us - they are shocked. They say something like this is incredibly rare at any zoo - and its even more unlikely at mesker park. Every child loves a trip to the zoo. And tigers are one of the highlight. Thats the case for these visitors saying hello to mesker park zoos Samatran Tiger Tsunami. With such a close view of the beast bouncing back and forth its easy to forget just how dangerous he is. But visitors in San Francisco know. "I was really shocked because it is so rare," says Charlotte Roesner with Mesker Park Zoo. A tiger attacked three visitors - killing one earlier this week. "Usually if an incident occurs its something that happens in a keeper area," because its unheard of that an animal would even get out of its exhibit. The tiger in San Franciso was kept in a grassy area surrounded by a moat. "Pur zoo had that same moat type setup for our lion exhibit". Visitors had to view the animal from the top of a 20 foot wall. Police believe to get out, the tiger jumped that wall. "Here in Evansville the setup is much different. Tsunami is kept behind a cage with no way to get out. The incident bears the question why are the animals in a zoo in the first place? "If we didnt have those animals in exhibits they wouldnt exist." Many including Tsunami are endangered. Hes here just like all the animals across the country to teach." The San Francisco incident isnt hurting attendance at Mesker Park. Today they saw at least 100 visitors a huge amount considering its the day after Christmas.
