The gray cat snake (Boiga siamensis), also known as eyed cat snake or Siamese cat snake is a species of catsnake found in northeastern India, Bangladesh, Myanmar, Cambodia, Thailand, Malaysia, and Vietnam.
The Siamese cat snake resembles the dog-toothed snake but it occupies a different geographical range. It is a large snake, reaching almost 2 m (6 1⁄2 ft) in total length. Colours are greyish-brown with black crossbars that are most distinct interiorly. The head is dark brown with a dark streak from behind the eye to the first body crossbar that is broken just beyond the last supralabial. The chin and throat are white, the ventrals white to light brown.
Behavior and venom
Mostly nocturnal, it is a potentially aggressive snake. It is a rear fanged venom snake but there are not known casualties registered. In 2014 while a study for the Prayao forest department (Thailand), herpetologist Frank Cuesta was bitten by a juvenile. The bite caused a very large edema along the entire arm and had to be treated at a hospital for over a month.
