Ceylon Cat Snake

The Ceylon cat snake is a small to moderately sized member of the genus Boiga found primarily in Sri Lanka, with a limited distribution extending into southern India. It shares the characteristic cat-like vertical pupils common to its genus, along with a subdued reddish-brown patterning.

It is a nocturnal species associated with forested and semi-forested habitats and is not commonly encountered by the general public.

As a rear-fanged species, it is mildly venomous, and its bite is not considered a significant health concern for humans.

• Small to moderate, slender body, reddish-brown to grayish-brown dorsally
• Faint darker blotches or crossbands, often less distinct than in larger Boiga species
• Broad head with vertically elliptical pupils
• Smooth scales
• Pale venter

Distinguished from other regional cat snakes primarily by its smaller size and more limited, Sri Lanka-centered range.

Inhabits forests, forest edges, and adjacent scrub and agricultural land in Sri Lanka and the southernmost parts of India. It is arboreal, using shrubs and low trees as well as ground cover.

It occurs from lowland to mid-elevation habitats within its range.

Nocturnal, emerging after dark to forage among vegetation. It tends to be secretive and relies on cryptic coloration, though it may display defensive posturing if disturbed.

Its diet includes small lizards and possibly other small vertebrates. It is oviparous, laying small clutches of eggs, though specific reproductive details are not extensively documented.
