When the Chinese gifted a pair of rare Panda Bears to the zoo, all eyes were on the place known to love and care for rare and exotic animals in conditions to provide comfort, food and a lifestyle to with many creature comforts taken and adapted from their native lands. You can spend an hour or two at the zoo, or stay the entire day. There are tram rides, sky rides, elevators to assist you along on the outdoor terrain, and sidewalks set aside for you to watch the animals and birds.
