Very little is known about the biology, behaviour and diet of the marbled cat, except what has been observed in captivity (6). The species is believed to be primarily nocturnal and more arboreal than most other cats, which would help explain its relative obscurity (2) (4), although recent studies have shown activity during both day and night (7). With its long, slender body, extremely long tail, short legs and broad feet, the marbled cat is well-adapted for tree-climbing and has been observed in trees in the wild, once stalking a bird, and is an adept climber in captivity (2) (6). Birds are thought to constitute a major part of the diet, and there have also been records of squirrels and rats being eaten, while lizards and frogs may also be taken (2) (6). Little is known about how far this secretive cat ranges, although one female, radio tracked in Thailand for a month, was found to have a home range of 5.3 square kilometres (10).
What is known of this cat’s reproductive behaviour comes from observations of just a few captive individuals. Two litters of two kittens have been recorded from January and February, and one litter of unknown size was born in September. Gestation is estimated to last somewhere between 66 and 82 days (2). Young attain sexual maturity at 21 to 22 months and individuals in captivity have lived up to 12 years and three months (2) (6).
