Habitat and range

Where each species lives and the conditions it tolerates.

Habitat types Differs

Fishing Cat

wetland, mangrove, agricultural mosaic, tropical rainforest

  • Wetland
  • Mangrove
  • Agricultural mosaic
  • Tropical rainforest

Marshes, reedbeds, oxbow lakes, mangrove creeks, tidal channels and flooded rice paddy — always close to permanent water with fish.

Rusty-spotted Cat

dry forest, tropical rainforest, semi-arid scrub, agricultural mosaic

  • Dry forest
  • Tropical rainforest
  • Semi-arid scrub
  • Agricultural mosaic

Deciduous forest, scrub, grassland with rock cover, bamboo and cultivated land; it is not restricted to dense forest as was once believed.

Geographic range Same

Fishing Cat

Asia

  • Asia

Scattered wetland populations in India, Nepal, Bangladesh, Sri Lanka, Myanmar, Thailand, Cambodia and Indonesia (Java), with historical records from several other countries.

Rusty-spotted Cat

Asia

  • Asia

Most of India, plus Sri Lanka and the Nepalese terai, with scattered records extending the known range in recent decades.

Diet and behaviour

Feeding ecology, social organisation and hunting technique.

Main prey Differs

Fishing Cat

fish, small mammals, birds, reptiles

  • Fish
  • Small mammals
  • Birds
  • Reptiles

Fish supply the majority of the diet, along with rodents, waterbirds, snakes, frogs and molluscs.

Rusty-spotted Cat

small mammals, birds, reptiles, insects

  • Small mammals
  • Birds
  • Reptiles
  • Insects

Rodents and small birds dominate, with lizards, frogs and insects taken regularly.

Social structure Same

Fishing Cat

Solitary

Adults hold ranges centred on water bodies. In several countries the species now lives largely inside human-dominated wetland, including aquaculture ponds and paddy landscapes.

Rusty-spotted Cat

Solitary

Nocturnal and secretive; most records come from camera traps, road surveys and occasional rescues of kittens from farmland.

Activity period Same

Fishing Cat

Nocturnal

Strongly night active, resting during the day in dense reed or scrub near water.

Rusty-spotted Cat

Nocturnal

Almost entirely night active, sheltering by day in tree hollows, rock crevices and abandoned structures.

Hunting strategy Differs

Fishing Cat

Aquatic ambush and diving

Waits at the water's edge and hooks fish with a forepaw, or swims and dives to take prey below the surface.

Rusty-spotted Cat

Rapid ground and tree hunting

Hunts small prey with quick rushes, and readily follows rodents and birds into trees.

Climbing ability Differs

Fishing Cat

Capable

Climbs competently but spends most of its time at ground and water level.

Rusty-spotted Cat

Exceptional More developed

Extremely agile in trees for its size, using branches for both hunting and shelter.

Swimming ability Differs

Fishing Cat

Exceptional More developed

One of the strongest swimmers among cats; it will swim long distances and dive fully underwater.

Rusty-spotted Cat

Very limited

Little recorded association with water.

Documented threats Differs

Fishing Cat

Wetland drainage and conversion, Aquaculture expansion, Retaliatory killing at fish ponds, Snaring and hunting, Pollution of waterways

  • Wetland drainage and conversion
  • Aquaculture expansion
  • Retaliatory killing at fish ponds
  • Snaring and hunting
  • Pollution of waterways

Wetland loss is the central problem: drainage, aquaculture conversion, pollution and settlement have removed much of the habitat this species requires, and remaining populations are highly fragmented.

Rusty-spotted Cat

Conversion of scrub and forest to cropland, Road mortality, Killing near poultry, Trapping and pet trade, Predation by domestic dogs

  • Conversion of scrub and forest to cropland
  • Road mortality
  • Killing near poultry
  • Trapping and pet trade
  • Predation by domestic dogs

Assessed as Near Threatened. Habitat conversion is the leading pressure, though records from farmland suggest more tolerance of modified landscapes than previously assumed.

Notable traits

Details that do not fit neatly into a measurement table.

Fishing Cat

  • Partial webbing between the toes of the forefeet helps with swimming and with scooping fish.
  • The species is the state animal of West Bengal, India.
  • Conservation projects increasingly work with fish farmers, since much remaining habitat lies on private land.

Rusty-spotted Cat

  • It competes with the black-footed cat for the title of the world's smallest wild cat.
  • Kittens are often mistaken for domestic kittens when found near villages.
  • Its known range has expanded considerably as camera trapping has spread across India.
