The White-spotted Cat Snake is a species of lowland rainforest, reportedly occurring up to elevations of 1100 metres. The species has also be sighted close to freshwater swamp forest habitat.

This snake has two colour forms. One form is predominantly green with faint bands of pale green with darker specks, or thin dark banding. The other form (illustrated here) is predominantly brown with thick bands of orange and minor bands of white speckling. The ventral surface is pale yellow to white.

This species is one of the most slender of all Cat Snakes (Boiga sp.), with a laterally compressed body. The width of the bulbous head is two to three times that of the neck. The eyes are large, with vertical pupils. 

It appears to be almost exclusively arboreal, feeding on a variety of prey including large insects, lizards, tree frogs, birds eggs and hatchlings. The female is known to sometimes lay its clutch of eggs in arboreal termite nests.

As with other Cat Snakes the species is rear-fanged and mildly venomous, but is not known to be aggressive.

The White-spotted Cat Snake ranges from southern Thailand, Peninsular Malaysia and Singapore to Sumatra, Java, Borneo and the southern Philippines.

In Singapore the species was recently rediscovered after not being seen for over 100 years.
