well sorry to jump in here as I do not own, nor have I worked with the beautiful JCP. I have heard that they can be nippy when younger, but then again what snakes aren't really nippy when younger (besides BP's ) I have also heard that they are very nice to keep as display animals and such. I believe I read earlier that they are semi-arboreal but that is just something i'm throwing out there because I think that I read that when I was researching them. Here are some links:
