The black-headed cat snake is arboreal, but frequently comes down to the ground in search of prey. They occupy lowland and mid-elevation tropical rainforests of Southeast Asia.Food
The black-headed cat snake feeds on lizards, frogs, birds, small mammals and other snakes in the wild.Defense
Little is known about the black-headed cat snake's venom toxicity on humans, but it is thought to be comparable to the severity of a copperhead. This rear fanged colubrid's bite rarely results in adverse effects due to its poor venom delivery system. Luckily their fangs' positioning doesn't result in any significant envenomation.Symptoms tend to stay localized to the envenomation site, limiting the victim to minor pain.
