I built my own cage, put about 600$ into it, making it awesome and getting everything perfect... and then I got more snakes. and then had no where to put them. Its all good to say that you only have three snakes so you only need space for three, but collecting is adictive.. I switched to racks that i build, holds 9 adults in one, and the other holds 10 sub adults and 16 babies, taking up the same amount of space as the one i had made and it only cost me 200$ for everything. It's saved me so much time and effort and the snakes seem happy and healthy.
I dont mean to be harsh, but just sharing from my own experiance.
