The collared cat snake is a nocturnal, tree-dwelling, rear-fanged colubrid endemic to south-western India. It is small to medium in length with a moderately long tail, reaching about 1.2 m, and has an egg-shaped head distinct from the neck with a rounded snout. The body is deep rusty brown with numerous rich reddish-brown crossbars (Wikipedia, general species account).
It prefers low to mid-elevation hills (300–1,200 m) in tropical evergreen and moist deciduous forests. It is occasionally seen on the ground searching for prey and especially feeds on Calotes lizards, though it can also eat tree frogs and geckos. It has recently been recorded in the southern Eastern Ghats in Tamil Nadu (Sirumalai, Shevaroys, Kolli Hills, Melagiri and BR Hills).
