Anyways, it was designed so that we walked above the animals on a wall (like a mini Great Wall of China, with animals on both sides). There weren't any fences over the animals. It was concrete and a few electric wires. Most of the walls were 9 to 15 feet high. Just knowing that if a leopard really wanted to eat you he could skip to the top of the wall was exciting. Hearing them roar added to that feel of fear. The lion roars reverberate through our chests. I wish we could experience that in the States but there is no way that kind of exhibit would be allowed!
