"Pet Paradise," a unique type of indoor zoo, recently appeared in several places in east China's Shanghai Municipality, attracting many visitors to closely interact with small animals. Zoolung Zoolung, an indoor zoo that opened last June, covers an area of 4,000 square meters. It has more than 80 small animals including toucans, auricular foxes, and capybaras. The total experience time is about two hours, during which staff members provide an all-round instruction, guiding visitors to feed and touch the animals.
