Fishing cats live in the wetlands of South and Southeast Asia, spread across countries including India, Nepal, Sri Lanka, Thailand, Bangladesh, Cambodia, and parts of Indonesia. They are true wetland specialists, sticking close to marshes, mangroves, swamps, and riverbanks in mostly lowland areas. Their distribution is patchy, though, tied to wherever suitable water and vegetation remain.
Countries and Geographic Range
India holds the largest known populations of fishing cats, with significant numbers in both freshwater floodplains and coastal estuarine habitats. Nepal’s southern lowland belt, known as the Terai, supports populations along rivers and marshes that stretch across the country’s flat southern border. Sri Lanka is home to fishing cats not only in wild wetlands but also in the urban fringes of Colombo. Thailand’s fishing cats make heavy use of rice paddies and coastal wetlands, and a recent study in southern Thailand documented population densities of 18 to 24 cats per 100 square kilometers.
Beyond these core countries, fishing cats have historically been recorded in Bangladesh, Cambodia, Myanmar, Vietnam, and Java in Indonesia. In many of these areas, populations are fragmented or declining as wetlands disappear. The species has a scattered, island-like distribution rather than a continuous range, which makes each remaining pocket of habitat critically important.
Wetlands Are Everything
When researchers track fishing cats and analyze where they spend their time, wetlands dominate every other habitat type. One study using GPS-collared cats found that while the animals physically spent the most time in tall grassland and shrub (about 32% of locations), wetlands were the only habitat they actively preferred. Every statistical measure of habitat selection pointed to wetlands as the top choice, both day and night.
The specific wetland types fishing cats use include freshwater marshes, mangrove forests, swamps, reed beds, tidal creeks, and the vegetated edges of rivers and ponds. Dense stands of cattails and similar tall aquatic plants are especially important. These thickets provide year-round cover for resting and denning, even in the dry season when surrounding vegetation dries out. Fishing cats also frequent the banks of slow-moving rivers and the shores of lakes and lagoons, anywhere shallow water and dense shoreline vegetation come together.
Key Protected Areas in India
The most thoroughly documented fishing cat populations are in India, where surveys have produced actual population estimates for several reserves. Among estuarine (coastal) habitats, the Sundarbans Tiger Reserve in West Bengal leads with an estimated 385 fishing cats. Chilika Lagoon in Odisha, one of Asia’s largest brackish-water lakes, supports roughly 341. Bhitarkanika National Park in Odisha holds between 83 and 115, and Coringa Wildlife Sanctuary in Andhra Pradesh has 95 to 100.
For freshwater floodplain habitats, Kaziranga National Park in Assam recently emerged as a stronghold, with at least 57 confirmed individuals. That makes it the highest recorded population in any floodplain ecosystem. Kishanpur Wildlife Sanctuary and Dudhwa National Park in Uttar Pradesh follow, with populations estimated between 35 and 51. Pilibhit Tiger Reserve in Uttarakhand holds 14 to 17, and Katerniaghat Wildlife Sanctuary has 12 to 14.
Life Outside Protected Areas
One of the more surprising facts about fishing cats is how many of them live outside national parks and wildlife sanctuaries. In India, roughly half of the fishing cat population is believed to occur in unprotected habitat. That includes agricultural landscapes, fish farms, and rice paddies, places where shallow standing water and fish attract these cats even though the land is actively used by people.
In Thailand, fishing cats make extensive use of paddy fields, hunting fish and frogs in flooded rice plots. In Nepal and India, they’ve been recorded around commercial fish ponds, where cattail thickets along pond edges provide cover. This ability to survive in human-modified landscapes is a double-edged sword. It means fishing cats aren’t entirely dependent on pristine wilderness, but it also brings them into frequent conflict with fish farmers and exposes them to roads, dogs, and pollution.
Fishing Cats in Cities
Perhaps the most remarkable example of fishing cat adaptability is in Colombo, Sri Lanka. About 15% of the metropolitan area is covered in wetland habitat, and fishing cats have established themselves as the city’s top land predator. An ongoing research project led by wildlife biologist Anya Ratnayaka has been studying this urban population, which navigates drainage canals, marshy vacant lots, and waterlogged areas woven through neighborhoods. These cats hunt at night in the city’s remaining wetland patches and rest in dense vegetation during the day. It’s one of the few documented cases of a wild cat species thriving inside a major city.
Elevation and Terrain
Fishing cats are primarily lowland animals, and most populations live near sea level or in low-lying river plains. But they aren’t strictly limited to flat ground. They’ve been recorded in forested areas of the Himalayas at around 1,525 meters (about 5,000 feet), and in Sri Lanka’s mountainous interior as high as 2,100 meters (roughly 7,000 feet). These high-altitude records are exceptions rather than the rule. The vast majority of fishing cats live below 100 meters elevation, in the kind of flat, water-rich terrain where marshes and floodplains naturally form.
What Makes Habitat Suitable
The common thread across every place fishing cats live is the combination of water, prey, and cover. They need water bodies that hold fish, frogs, and crustaceans. They need dense vegetation along the water’s edge for concealment while hunting and for daytime resting spots. And they need these features to persist year-round, not just during the monsoon season. Permanent marshes with standing water and tall reed beds are the gold standard.
When any of these elements disappears, fishing cats disappear too. Wetland drainage for agriculture and development is the primary threat across their range. In many parts of Southeast Asia, mangrove forests have been cleared for shrimp farming, and inland marshes have been drained for construction. The fishing cat’s tight dependence on wetlands means it functions as an indicator species: where fishing cats are present, the wetland ecosystem is still functioning. Where they’ve vanished, the wetland has likely been degraded beyond recovery.
