I think cage designing is the second best thing next to actualy owning your ball. If you can make a comfortable enclosure for your little friend, while at the same time making a decent looking reptarium and keeping your room looking good you have done a really good job. I try not to change my tank to much because of the stressfullness for the snake but sometimes I might move things around or add a little bit. I usualy change my designs everytime I clean the tank. 8)
