Clouded Leopard (Neofelis nebulosa)
All the Bornean wild cat species are basically similar to the domestic cat in body form and have 28-30 teeth. They are distinguished mainly by size, tail length and coloration. All cats have four toes on the hind feet and five on the front feet, but the inner front toe is small and leaves no impression on the ground. The claws are retractile, and do not appear in footprints. There is no definite evidence that either the Tiger, Panthera tigris, or the Leopard, Panthera pardus. occur in Borneo.
Measurements: Total length from nose to tip of tail 1.5 m or more.
Identification: The largest cat known to occur in Borneo. Varies from very pale sandy brown to very dark. Almost always has a pattern of cloud-like markings on the sides of the body - totally black specimens have been reported but not confirmed. The upper canines are very relative to the skull with a clear gap between them and the cheek teeth.
Similar species: the Marble Cat, Felis marmorata, and other cats are smaller; the Binturong, Arctictis binturong, is sometimes mistaken for a black Clouded Leopard, but has long shaggy hair, ear tufts, no coat pattern and a prehensile tail.
Ecology and Habitat: Mainly nocturnal and arboreal, but sometimes active during the day. In logged forest, often travels on the ground. Diet includes pigs, deer, monkeys, Orang-utans and similar mammals. Occurs in tall and secondary forests, sometimes in mangrove; rarely enters plantations.
Distribution: N.n. diardi. Recorded from many scattered localities; many parts of Sarawak.
