Yellow-green Cat Snake is a nocturnal and semi-arboreal species which shows activity both at moderate heights of vegetation and rocks found in its habitat. Locomotion slow like most of the Cat snakes. Behavior shy, elusive and usually non-offensive. On threatening it throws much of fore body into tight loops with head above the ground to frighten its enemy. Gives regular mock attacks to maintain safe distance. Gives chew bite on rough handling. Reproduction oviparous. No specific information is known about its breeding biology. Like most of the snakes of India new born of this species are expected in monsoon months with mating time possible during summer.
Diet: 
Feeds on lizards, frogs and rodents.
Threats: 
Threats includes killing due to misidentification with venomous species like Bamboo Pit Viper. As this species lives majorly in rocky hills, population of it largely depends on status of such rocky hills and vegetation covering them.
