A cat shaped by water

The flat-headed cat belongs to the narrow edge between forest and freshwater.

With a low forehead, forward-set eyes, narrow feet, and unusually developed webbing between the toes, the flat-headed cat looks different because it lives differently. Its anatomy points toward slippery aquatic prey and hunting at the water’s edge.

It is smaller than the fishing cat and more tightly associated with lowland wetlands. Fish are important, but frogs, crustaceans, rodents, and other prey may also form part of a diet that remains incompletely known in the wild.

Habitat and range

Follow the rivers, swamps, and peatlands—and then ask whether the water still works.

The flat-headed cat survives on Sumatra, Borneo, and the Malay Peninsula, with most records close to freshwater. It uses riverine forest, peat swamp, freshwater swamp, marshes, and other wet lowlands, generally below 100 meters elevation.

Its distribution is naturally patchy because suitable wetlands are patchy. Drainage, dams, plantations, and pollution do more than remove cover: they alter the water and prey system that makes the habitat usable at all.

The conservation reality

When a wetland is simplified, a specialist loses more than space.

The flat-headed cat is Endangered. Much of its historical lowland habitat has been transformed, and remaining populations are fragmented across some of Southeast Asia’s most intensively altered landscapes.

What effective work looks like

Conserve the water system, not only the strip of trees beside it.

The species needs wetland conservation that treats forest cover, water quality, prey, and human use as one connected system.

Survey the overlooked waterways

Targeted camera trapping and environmental DNA can clarify where the species persists and which wetland connections matter most.

Keep water clean and connected

Protecting peatlands, river margins, natural flow, and aquatic prey addresses the ecological system behind the cat.

Build safeguards into working landscapes

Better plantation management, reduced chemical runoff, and removal of snares can improve survival beyond protected-area boundaries.

From hope to participation

A small wetland cat can change how we value an entire waterway.

Zoo-EV will look for field partners who connect species evidence with peatland, river, and community stewardship. Until then, participation begins with recognizing that clean, functioning wetlands protect far more than the animal in the photograph.
