Boiga andamanensis, known commonly as the Andaman cat snake, is a species of rear-fanged snake in the family Colubridae. The species is endemic to the Andaman Islands.
The body of B. andamanensis is long, thin, and laterally compressed, with smooth dorsal scales. The head is distinctly broader than the neck. The eye is large, and has a vertical pupil. The tail is long. Dorsally, the Andaman cat snake is pale reddish or greyish brown, uniform, or with a series of dark brown vertebral spots or thin cross-lines. There is dark colour usually on the scale edges. The markings are most distinct on the forebody. The top of the head has faint, dark brown or black lines. The upper lip scales are white, the last few with thin black rear edges. There is an indistinct black line from behind the eye to the angle of the mouth. The underside of the body is white or yellowish, usually with a series of black spots on each side. Juveniles and sub-adults are similarly patterned, and usually dark orange above, paler below. Most of the scales on the top of the head vary in shape and size, and are distinctly larger than the dorsal scales. The average adult total length (including tail) is approximately 0.85 metres (2.8 ft), [3] but it may grow to a total length of 1.49 metres (4.9 ft). [4]
Dorsal scales in 21:21:15 oblique rows, smooth; vertebral scales distinctly enlarged. Ventrals 255–269, strongly angulate laterally; anal entire; subcaudals 118–133, paired. Loreal 1; preocular 1, reaches upper surface of head, often touches frontal; postoculars 2, rarely 3; temporals 3+3 or 3+4; supralabials 8 (3rd to 5th touching eye).
B. andamanensis is endemic to the Andaman islands of India. [4]
The Andaman cat snake is a forest species and is also frequently found in thatched roofs of houses. [4]
B. andamanensis is nocturnal and arboreal. It is occasionally seen on the ground searching for prey. It generally has a mild disposition but has been observed to strike when approached. If provoked it will raise its forebody, coil into loops, often vibrating its tail, and bite readily. It is a rear-fanged snake and has a mild venom which can paralyze small prey. [4] It preys mainly on geckos, other small lizards (especially lizards of the genus Calotes ), and rodents, but will occasionally eat tree frogs and bats. [3]
Boiga is a large genus of rear-fanged, mildly venomous snakes, known commonly as cat-eyed snakes or simply cat snakes, in the family Colubridae. Species of the genus Boiga are native to southeast Asia, India, and Australia, but due to their extremely hardy nature and adaptability, have spread to many other suitable habitats around the world. There are 38 recognized species in the genus. According to the study done by Jiří Smíd regarding Old World cat snakes, the ancestor of the cat snake originated in Africa, from where it diversified and expanded to other countries. Despite this diversity however, the different species have very similar needs in terms of temperature and precipitation.
Boiga beddomei, commonly known as Beddome's cat snake, is a species of rear-fanged snake in the family Colubridae. The species is endemic to the Western Ghats of India, in Maharashtra, Gujarat and Goa states.

Although moderate envenomations resulting in intense swelling have been reported, there has never been a confirmed fatality.

Chrysopelea ornata is a mildly venomous opisthoglyphous (rear-fanged) colubrid snake found in both South and Southeast Asia. Along with the other species in the Chrysopelea genus, the golden tree snake is very unusual, as it is capable of a type of gliding “flight” —mainly utilised during the pursuit of prey animals—from tree-to-tree. This action is also used to great effect for the snake to flee its own potential predators. Currently, three subspecies are recognised. The snake's striking looks, and potential for gliding, have made it a coveted choice for captivity.
Boiga drapiezii, commonly known as Drapiez's cat snake and the white-spotted cat snake, is a species of long and slender rear-fanged snake in the family Colubridae. The species is native to Maritime Southeast Asia and is common throughout its range.
