The clouded leopard (Neofelis nebulosa), also called the mainland clouded leopard, is a wild cat inhabiting dense forests from the foothills of the Himalayas through mainland Southeast Asia into South China. In the early 19th century, a clouded leopard was brought to London from China and described in 1821. It has large dusky-grey blotches and irregular spots and stripes reminiscent of clouds. Its head-and-body length ranges from 68.6 to 108 cm (27.0 to 42.5 in) with a 61 to 91 cm (24 to 36 in) long tail. It uses its tail for balancing when moving in trees and is able to climb down vertical tree trunks head first. It rests in trees during the day and hunts by night on the forest floor.
