Its chin, throat, inner side of the limbs and belly are whitish with tiny brownish spots. Its paws and tail are uniform reddish gray.
Captive ones are mostly nocturnal but also briefly active during the day. At Horton Plain National Park in Sri Lanka, they were mostly recorded between sunset and sunrise, with limited daytime activity.
Several individuals were observed hiding in trees and in caves. It feeds mainly on rodents and birds, but also preys on lizards, frogs, and insects.
It hunts primarily on the ground, making rapid, darting movements to catch its prey. It apparently ventures into trees to escape larger predators.
Captive females and males both scent-mark their home range by spraying urine. The female'estrus lasts five days, and mating is unusually brief.
Since the female is likely to be vulnerable during this period, its brevity may be an adaptation to help it avoid larger predators. She prepares a den in a secluded location, and after a gestation of 65–70 days gives birth to one or two kittens.
At birth, the kittens weigh just 60 to 77 g (2.1 to 2.7 oz), and are marked with rows of black spots. They reach sexual maturity at around 68 weeks, by which time they have developed the distinctive adult coat pattern of rusty blotches.
The Sri Lankan population is included on CITES Appendix II. The species is fully protected over most of its range, with hunting and trade banned in India and Sri Lanka.
