IMPORTANT: Many snakes have significant variance in coloration and pattern even within the same species. There can also be extreme differences in appearance from juveniles to adults so it is important to never assume you have properly identified a snake.

The Jasper Cat Snake is a largely arboreal snake and as such is prone to seek out high ground when confronted. They also commonly display initial aggressive behavior by positioning their front half into a defensive 'S' position. They will strike with largely false bites and occasionally real hits, but their diminutive size renders any genuine bite relatively harmless. Capable of puffing up their throat into a distinct sphere shape when defensive.


Due to their largely arboreal nature Jasper Cat Snakes are generally found in forested areas, often close to some water source. They have also been observed in more open areas like fern groves. During the day they hide in hollow logs or under ledges closer to the ground.


NO SNAKE SHOULD EVER BE HANDLED BY ANYONE BUT EXPERTS: The Jasper Cat Snake is a relatively uniquely patterned snake and is difficult to mistake with other species especially when considering their arboreal behaviors.
