There are, of course, a lot of trials. One, for example, is feeding of giraffes, for example. In my mind, that’s the wrong way to go. We should respect the animals as they are and we should be able to observe their natural feeding and not to give tidbits at the border of the enclosure. I think just a guided tour is already helping very much. The visitor wants to learn more about individual specimens, their favorites. Youngs that were born and became famous in the zoo and in the city. I, for example, I always had a big dispute with my staff about guided tours.
