How to Identify Beddome's Cat Snake (Identification Guide)

Key identifying features

Beddome's Cat Snake (Boiga beddomei) is identified by a series of darker brown blotches over a lighter tan or grayish-brown background, along with a broad head clearly distinct from the neck and the large, vertically slit pupils shared by all cat snakes. Its restricted range within the Western Ghats of India is an additional helpful clue for identification.

Coloration & pattern

The base coloration is typically a light to medium brown or grayish-tan, marked with a series of darker brown or blackish blotches running along the back, sometimes forming loosely connected bands in places. The pattern provides camouflage against bark and leaf litter in its forest habitat. The belly is usually pale, often cream or light yellow, and largely unmarked.

Head, eyes & scales

The head is broad and clearly wider than the neck, consistent with the cat snake body plan, and may show additional dark markings or streaking that continues from the body pattern. The eyes are large, with vertical pupils adapted for low-light activity, a hallmark trait of the genus. Scales are smooth, giving the snake a glossy sheen.

Size & body shape

Adults typically reach around 1 to 1.4 meters in length, a moderate size for a cat snake. The body is slender and laterally compressed for climbing, with a long, tapering tail that assists with balance while moving through vegetation and branches.

Range & habitat where you'll see it

This species is largely restricted to the Western Ghats mountain range of southwestern India, inhabiting moist forests and hill country with substantial canopy cover. It is nocturnal and arboreal, sheltering during the day in tree hollows or dense foliage and emerging at night to hunt.

How to tell it apart from look-alikes

Beddome's Cat Snake can be distinguished from the widespread Common Cat Snake by its more restricted range within the Western Ghats and its somewhat different blotch pattern and coloration. It differs from the uniformly green-toned Green Cat Snake and from finely spotted species like the Many-spotted Cat Snake by its moderate, connected blotching. Its localized distribution within a specific mountain range is often the most practical clue for confirming identification in the field.
