I notice many different levels of decor for balls. My question is this. How necessary is all the stuff for the health and happiness of our pets? I realize a lot of it makes the cage look cool, and appealing to us, but does the snake care? I also noted that the breeder I dealt with, as well as many others I've seen, has only a hide and a water dish for each snake. These snakes appeared very healthy and content. What are your thoughts?
