# Clouded Leopard — Facts, Threats & Conservation

*Neofelis nebulosa & Neofelis diardi*

> A clouded leopard is a medium-sized arboreal wild cat native to the forests of Asia, recognised by its cloud-shaped coat patches and famous for having the longest canine teeth relative to body size of any living cat; two species exist, the mainland (Neofelis nebulosa) and Sunda (Neofelis diardi) clouded leopards, both listed as Vulnerable.

**IUCN status:** Vulnerable (both species) — island subspecies assessed Endangered  ·  **WARN range:** Indonesia, Malaysia

## Scientific classification
- **Kingdom:** Animalia
- **Phylum:** Chordata
- **Class:** Mammalia
- **Order:** Carnivora
- **Family:** Felidae
- **Subfamily:** Pantherinae
- **Genus:** Neofelis
- **Species:** Neofelis nebulosa (Griffith, 1821) — mainland; and Neofelis diardi (Cuvier, 1823) — Sunda

## Conservation status
- **Status:** Vulnerable
- **Population:** Mainland (N. nebulosa): ~3,700–5,580 mature individuals; Sunda (N. diardi): fewer than 10,000 mature individuals
- **Trend:** Decreasing
- **Assessed:** Mainland assessed 2021 (IUCN Red List 2022.2); Sunda assessed 2015
- **CITES:** Appendix I (both species)
- Both species are rated Vulnerable, but the two Sunda subspecies — Bornean (N. d. borneensis) and Sumatran (N. d. diardi) — are each assessed as Endangered. Estimates carry wide uncertainty because these cats are elusive and live at low densities.

## Key facts: Clouded Leopard
- Two distinct species exist: the mainland clouded leopard (Neofelis nebulosa) and the Sunda clouded leopard (Neofelis diardi), split into separate species in the mid-2000s based on genetic and pelt differences.
- Relative to body size, clouded leopards have the longest canine teeth of any living cat — around 4 cm (about 2 inches) — earning them the nickname 'modern-day sabre-tooth'.
- They are among the most arboreal of cats: rotating ankle joints let them climb down trees headfirst and even hang from branches by their hind feet.
- Both species are assessed as Vulnerable by the IUCN with decreasing populations; the mainland species is estimated at roughly 3,700–5,580 mature individuals.
- Within WARN's network range, the Sunda clouded leopard occurs in Indonesia (Borneo and Sumatra) and Malaysia (Borneo), where oil-palm-driven deforestation is a leading threat.
- Both species are listed on CITES Appendix I, banning commercial international trade, yet illegal hunting for skins, teeth and bones continues.

## Two species, one cloud-patterned cat
For most of the 20th century all clouded leopards were treated as a single species. Genetic and morphological studies in the mid-2000s showed that the island populations of Borneo and Sumatra were distinct enough to be recognised as a separate species, Neofelis diardi, the Sunda clouded leopard, leaving the mainland populations as Neofelis nebulosa. The two look similar but differ in detail: mainland cats tend to have larger, paler cloud markings with fewer interior spots, while Sunda cats are darker with smaller, more densely spotted clouds. The Sunda species is itself divided into two subspecies, the Bornean (N. d. borneensis) and Sumatran (N. d. diardi) clouded leopards, both of which the IUCN has assessed as Endangered even though the species overall is rated Vulnerable.

## Built for the canopy
Clouded leopards are arguably the most accomplished tree-climbers among the wild cats. They have short, powerful legs, broad paws and exceptionally flexible ankle joints that can rotate roughly 180 degrees, letting them descend trunks headfirst, run along the undersides of branches and hang by their hind feet. A tail almost as long as the body acts as a balancing pole. Their most striking feature is dental: their upper canines are the longest of any living cat relative to skull and body size, reaching about 4 cm, which has led scientists to compare them loosely to the extinct sabre-toothed cats. They are largely nocturnal and secretive, hunting birds, monkeys, deer, wild pigs and small mammals both in the trees and on the ground.

## Why they are threatened
Both clouded leopard species are in decline, and the IUCN infers a population reduction of more than 30 percent across recent generations for the mainland species. The dominant pressures are habitat loss and fragmentation — Southeast Asia has some of the world's fastest rates of forest clearance, much of it for oil-palm and other plantations — together with hunting. Clouded leopards are killed deliberately for their distinctively patterned skins, teeth and bones, which feed illegal wildlife markets and traditional medicine, and are caught incidentally in the wire snares set across their range for other animals. Because they are elusive and live at low densities, reliable range-wide population counts are difficult, and estimates carry wide uncertainty.

## What rescue and protection involve
Protecting clouded leopards is mostly about protecting forest and stopping snaring rather than hands-on animal rescue, because wild individuals are rarely seen. Practical work in their range includes anti-poaching and snare-removal patrols, camera-trap monitoring to track where cats survive, securing and connecting protected forest blocks, and caring for cubs and adults confiscated from the illegal pet and skin trade. In Indonesia and Malaysia, this depends on locally based ranger teams, wildlife rescue centres and sanctuaries that can respond to seizures and rehabilitate animals where possible.

## Mainland vs Sunda clouded leopard
| Feature | Mainland (Neofelis nebulosa) | Sunda (Neofelis diardi) |
| --- | --- | --- |
| Range | Mainland Asia: Himalayas to Indochina and Peninsular Malaysia | Islands of Borneo and Sumatra |
| Coat pattern | Larger, paler cloud blotches with few inner spots | Smaller, darker clouds with many inner spots |
| IUCN status | Vulnerable (2021) | Vulnerable (2015); both subspecies Endangered |
| Population estimate | ~3,700–5,580 mature individuals | Fewer than 10,000 mature individuals |
| CITES | Appendix I | Appendix I |
| WARN range overlap | Largely outside WARN's five countries | Within Indonesia and Malaysia — WARN's funded focus |

## What WARN does
WARN CIC is a registered global not-for-profit animal welfare organisation that funds local partner shelters, sanctuaries and rescue teams in Pakistan, Indonesia, Malaysia, Brazil and Colombia. The Sunda clouded leopard's range falls squarely within two of those countries — Indonesia and Malaysia — so this species sits inside WARN's funded focus: supporting partners that run anti-snaring patrols, monitor forests and care for confiscated wildlife on Borneo and Sumatra. The mainland clouded leopard ranges across other Asian countries outside WARN's five, so for those populations WARN's role is education and awareness rather than direct funding, and we are honest about that limit.

A gift to WARN helps fund the local Indonesian and Malaysian partners working to keep Borneo's and Sumatra's forests standing and snare-free — the difference between a future with the Sunda clouded leopard and one without.

## Frequently asked questions: Clouded Leopard
### How long do clouded leopards live?
In human care they commonly live to about 11 years, with some individuals reaching around 17. Lifespan in the wild is poorly documented but is generally believed to be shorter.

### What do clouded leopards eat?
They are carnivores that hunt a range of prey including monkeys, deer, wild pigs, porcupines, squirrels, birds and other small to medium mammals, taking prey both in trees and on the ground.

### How big is a clouded leopard?
They are medium-sized cats, weighing roughly 11.5–26 kg (about 25–57 lb) depending on species and sex, with a head-and-body length of about 69–108 cm and a tail nearly as long as the body.

### Are clouded leopards dangerous to humans?
No. Clouded leopards are shy, secretive and largely nocturnal, and there are no records of them being a meaningful danger to people. They avoid humans and are far more threatened by us than we are by them.

### How many clouded leopards are left?
There is no precise count. The mainland clouded leopard is estimated at roughly 3,700–5,580 mature individuals, and the Sunda clouded leopard at fewer than 10,000 mature individuals; both populations are decreasing.

### Why are clouded leopards endangered?
Both species are assessed as Vulnerable, mainly because of rapid deforestation for plantations and logging, deliberate hunting for their skins, teeth and bones, and accidental capture in snares. Island subspecies in Borneo and Sumatra are rated Endangered.

### What is a baby clouded leopard called?
A baby clouded leopard is called a cub. Litters usually contain one to five cubs, most often two or three.
