clouded leopard

:  either of two medium-sized, often arboreal cats (Neofelis nebulosa of mainland southeast Asia and N. diardi of Borneo and Sumatra) that are grayish to yellowish with darker irregular rings, ovals, and rosettes … new analysis shows the clouded leopards of Borneo (and also Sumatra) are a bit darker than their mainland cousins, with smaller cloud-shaped markings. — Helen Fields
