Dense perennial forest, including peat swamps, lowland forests, and hill forests.

The Sunda Clouded Leopard is a powerful, large cat with strong climbing skills (indeed some people do not consider it a small cat). Active mostly at night and twilight, it uses both ground and canopy, and requires large, continuous forest blocks.

Preys on medium-sized mammals such as bearded pigs, deer, primates, and smaller mammals, as well as birds. It is considered an Apex predator in its habitat.
