Habitat and range

Where each species lives and the conditions it tolerates.

Habitat types Differs

Sunda Leopard Cat

tropical rainforest, montane forest, agricultural mosaic, mangrove

  • Tropical rainforest
  • Montane forest
  • Agricultural mosaic
  • Mangrove

Lowland and hill forest, secondary growth, plantation edges and farmland; the species uses oil-palm landscapes where rodents are abundant and cover remains.

Flat-headed Cat

wetland, tropical rainforest, mangrove

  • Wetland
  • Tropical rainforest
  • Mangrove

Peat swamp forest, riverine forest and freshwater swamp in lowland areas, almost always within a short distance of water.

Geographic range Same

Sunda Leopard Cat

Asia

  • Asia

Java, Bali, Borneo, Sumatra, Palawan and other Philippine islands, and smaller islands across the Sunda Shelf.

Flat-headed Cat

Asia

  • Asia

Peninsular Malaysia, southern Thailand, Borneo and Sumatra, in an increasingly fragmented set of lowland wetland sites.

Diet and behaviour

Feeding ecology, social organisation and hunting technique.

Main prey Differs

Sunda Leopard Cat

small mammals, birds, reptiles, insects

  • Small mammals
  • Birds
  • Reptiles
  • Insects

Rats and mice dominate, along with birds, lizards, frogs and invertebrates.

Flat-headed Cat

fish, amphibians, small mammals, insects

  • Fish
  • Amphibians
  • Small mammals
  • Insects

Fish, frogs and crustaceans dominate, with rodents and insects taken as well.

Social structure Same

Sunda Leopard Cat

Solitary

Common in many surveys and comparatively tolerant of modified landscapes, provided some cover and rodent prey persist.

Flat-headed Cat

Solitary

Very rarely observed; almost all modern records come from camera traps set along watercourses.

Activity period Same

Sunda Leopard Cat

Nocturnal

Strongly night active, with camera-trap records clustering well after dark.

Flat-headed Cat

Nocturnal

Night active, with occasional records around dusk.

Hunting strategy Differs

Sunda Leopard Cat

Active ground search

Patrols plantation rows, forest edge and stream banks, hunting rodents and ground-nesting birds.

Flat-headed Cat

Shallow-water grabbing

Hunts by wading in shallow water and seizing prey with the forepaws, plunging the head beneath the surface.

Climbing ability Differs

Sunda Leopard Cat

Strong More developed

Climbs and dens in trees, though most hunting is terrestrial.

Flat-headed Cat

Capable

Climbs adequately but forages almost entirely at water level.

Swimming ability Differs

Sunda Leopard Cat

Strong

Swims capably, which has helped the species reach numerous islands.

Flat-headed Cat

Exceptional More developed

Highly aquatic, with partially webbed feet and a strong association with permanent water.

Documented threats Differs

Sunda Leopard Cat

Forest conversion to plantation, Snaring and hunting for skins, Rodenticide use in plantations, Road mortality, Pet trade

  • Forest conversion to plantation
  • Snaring and hunting for skins
  • Rodenticide use in plantations
  • Road mortality
  • Pet trade

Still widespread and locally common, but hunting for skins, snaring and the conversion of forest to plantation reduce numbers in parts of the range.

Flat-headed Cat

Drainage of peat swamp forest, Conversion to oil-palm plantation, Water pollution and fish depletion, Snaring, Extreme habitat fragmentation

  • Drainage of peat swamp forest
  • Conversion to oil-palm plantation
  • Water pollution and fish depletion
  • Snaring
  • Extreme habitat fragmentation

Assessed as Endangered, with a very small estimated population. Over two-thirds of the lowland wetland habitat it depends on has been drained, converted or degraded.

Notable traits

Details that do not fit neatly into a measurement table.

Sunda Leopard Cat

  • The species was separated from the mainland leopard cat in 2017 on genetic and morphological evidence.
  • It is one of the few wild cats that appears to benefit, at least temporarily, from rodent booms in plantation landscapes.
  • Island populations vary enough in size and markings that further taxonomic work is likely.

Flat-headed Cat

  • Its eyes are set unusually far forward, giving the wide binocular field needed to judge prey underwater.
  • The claws retract only partly, leaving them permanently ready for gripping.
  • Captive individuals have been recorded washing food in water before eating.
