I am considering getting a pair of pine snakes this year and I was hoping that you all could give me some guidance as to what a good cage size would be for an adult. Since pines can get rather large, I was looking at some of the advice the boa folks were giving about their set ups. Would a 3x2x2 design be sufficient? I was thinking about building 2 display cages that would be stackable. Alternatively, would a rack system with sweater boxes be the better way to go?
