Flat-headed Cat Facts: Webbed Feet, Pets and Why They Are Endangered

Flat-headed cat Prionailurus planiceps

Red List Status: Endangered

Locations: Scattered and restricted populations in the lowland tropical rainforests, peat swamps, and coastal wetlands of Borneo, Sumatra, Peninsular Malaysia, and extreme southern Thailand.

Appearance and behaviour

Flat-headed cats have highly distinctive, almost mustelid (weasel-like) appearances that perfectly suit their semi-aquatic lifestyles. Their heads are exceptionally long, cylindrical, and flattened on top, equipped with short snouts and eyes set close together to provide excellent stereoscopic vision for tracking fish underwater. They have thick, short coats that are reddish-brown on their heads, dark roan brown on their bodies, and feature mottled white underbellies, with striking white streaks running from their noses to their eyes.

Flat-headed cats webbed feet are like fisherman’s boots

Unlike most felines, the cats’ claws do not fully retract, much like cheetahs, providing excellent grip on slippery rocks, useful for hunting. Flat-headed cats webbed feet are another remarkable adaptation to their environment. Their legs are relatively short, ending in long, narrow feet with prominent interdigital webbing that gives them excellent traction, stopping them from slipping. Although rarely caught on camera, while hunting, flat-headed cats are known to completely submerge their heads to snatch prey and often carry their catches several metres away from the shoreline to prevent them from escaping back into the water.

Threats

There are many reasons why the flat-headed cat is endangered on the Red List. They are considered some of the most threatened felines in the world due to their extreme specialisation and the rapid destruction of their specific wetland habitats for palm oil and mining.

Flat-headed cats and palm oil

The single greatest threat to flat-headed cats is the complete annihilation of their habitats for industrial agriculture. Over 70% of their historically suitable habitats have been transformed into unsuitable land, driven primarily by the relentless expansion of oil palm plantations across Southeast Asia. Flat-headed cats and palm oil are a dangerous combination. Unlike some adaptable species, flat-headed cats generally cannot survive or reproduce in monoculture plantations. When swamp forests are drained, logged, and bulldozed to plant oil palms, the cats lose their homes, their hunting grounds and their lives.

Wetland pollution and pesticide run-off

Their absolute dependence on fresh water makes them highly vulnerable to aquatic degradation. The run-off from agricultural fertilisers, pesticides used in oil palm plantations, and debris from destructive logging operations severely pollute the rivers and peat swamps they rely on. Furthermore, widespread overfishing by humans depletes the fish stocks that form the foundation of their diets, effectively starving the remaining populations.

Hunting and trapping

While not heavily targeted for the international wildlife trade, flat-headed cats are frequently the victims of incidental trapping. They are known to be caught in snares and traps set by local people intended for other bushmeat species or placed to protect domestic poultry. As their natural habitats shrink and they are forced into closer proximity with human settlements, the risk of deadly human-wildlife conflict dramatically increases.

Keeping a flat-headed cat pet

The exotic appearance and rarity of flat headed cats make them attractive targets for the illegal pet trade, despite strict legal protections. Keeping the endangered flat headed cat as a pet would be cruel to the individual and fatal to the species. This threat compounds why the flat-headed cat is endangered in the wild. Any cat removed from their swamp home steals a breeding individual from a collapsing population. Moreover, domestic settings cannot provide live fish prey, wetlands or night hunting opportunities that they require to survive.

Geographic Range

Their range is highly restricted and heavily fragmented. They are endemic to the Sundaland region, found only in the lowland tropical rainforests and wetlands of Borneo (Malaysia, Indonesia, and Brunei), Sumatra (Indonesia), Peninsular Malaysia, and a tiny sliver of extreme southern Thailand. They are rarely found at high elevations; the vast majority of records place them below 100 metres above sea level and almost exclusively within three kilometres of significant water sources like rivers, lakes, and coastal peat swamps.

Diet

Flat-headed cats are highly specialised carnivores with almost exclusive preferences for aquatic prey. Fish form the bulk of their diets, and their long, sharp anterior premolars and powerful jaws are perfectly evolved to seize and grip slippery, struggling aquatic animals. They also hunt for frogs, crustaceans, and shrimp along muddy riverbanks. While fish are their primary food sources, they are opportunistic and will occasionally take small rodents, birds, and even domestic chickens if given the chance. Interestingly, captive individuals have been observed “washing” their food and objects in water, displaying raccoon-like behaviours.

Mating and reproduction

Due to their extreme rarity and secretive nature, very little is known about these cats and their mating habits in the wild. Most data comes from the handful of individuals kept in captivity. They appear to be solitary outside of the mating season. Their gestation periods are relatively short, lasting approximately 56 days. Unlike many other small cats that have larger litters, flat-headed cats typically give birth to very small litters, often just single kittens, or occasionally two. These low reproductive rates make it exceptionally difficult for their populations to recover from heavy losses.

FAQs

Take Action!

Flat-headed cats cannot survive the draining of their wetland homes. You can help protect them by refusing to support the industries that clear their habitats. Choose a #vegan lifestyle to reduce the demand for agricultural land expansion, and avoid products containing palm oil, which is the leading driver of deforestation in their range. Stand up for these unique wetland ghosts and #BoycottPalmOil #Boycott4Wildlife.

Support Flat-headed cats by going vegan and boycotting palm oil in the supermarket, it’s the #Boycott4Wildlife
