In captivity, it was discovered that Flatheaded Cats possess a "raccoon-like" quality and will wash objects in water.
Sightings indicate that the Flatheaded Cat prefers swampy areas, oxbow lakes and riverine forests. It has also been seen hunting rodents in oil palm plantations.
The Flatheaded Cat can be found in Indonesia, Malaysia, Myanmar, Thailand, Singapore and Brunei.
Flatheaded Cats take readily to water and show no hesitation at completely submerging their heads in search of prey.
The Flatheaded Cat has a long sloping snout with the top of the skull being flattened, and it has unusually small ears.
Its eyes are large and close set which allow for maximum binocular vision.
Flat Headed Cats do not have completely retractile claws. They can be seen at all times, but do not rub up against the ground.
A Flatheaded Cat has feet even more completely webbed than the Fishing Cat.
