Flat-headed Cat

Prionailurus planiceps

A tiny riverside cat of Sundaland with backward-pointing teeth, close-set eyes and claws that cannot fully retract, all suited to gripping slippery prey.

Everything about this cat points to a diet of fish and frogs. The jaw is long and narrow, the premolars are sharp and backward-angled, the eyes sit far forward for binocular vision at close range, and the claws remain partly exposed even when retracted.

It is confined to lowland freshwater habitat in one of the most heavily converted regions on the planet, which is why it is considered one of the most threatened small cats in Asia.

Habitat and range

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

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

  • Wetland
  • Tropical rainforest
  • Mangrove

Diet and hunting

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

Hunting strategy — Shallow-water grabbing. Hunts by wading in shallow water and seizing prey with the forepaws, plunging the head beneath the surface.

Behaviour and activity

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

Nocturnal. Night active, with occasional records around dusk.

Climbing and swimming

Climbing — Capable. Climbs adequately but forages almost entirely at water level.

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

Conservation status

The Flat-headed Cat is currently listed as Endangered on the IUCN Red List, with a population trend recorded as decreasing in the assessment published in 2015.

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.

Documented threats

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

Notable traits

  • 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.
