The only colubrid I have is a Northern Pine Snake. Out of the three snakes I have (Ball Python, Northern Pine Snake, Boa Constrictor) he is the only one I call "fun". Do check them out.

They just have a heck of a lot of personality can can be just down right goofy. Mine loves to explore everything, and wants to crawl all over everything, too, almost to the point of being annoying. Rather like a child. I'm really glad I got him and recommend them.

Pros: Funny, curious, personality, outstanding eaters.
Cons: Poo a lot (more than they eat it seems), no warning when they are going to do so (you will learn to have paper towel with you). Shedding seems to take an obnoxiously long time but he's in his first shed with me.
