So instead of the normal substrate ideas, I was thinking of using the methods on lizard-landscapes to make a Viv for my balls and was wondering if this should be fine for them? and had some questions about a few ideas I had. I was thinking about the # of hides in the enclosure (which will be 48x30x24) and I came up with a 2 layer bottom, like an under layer that is maybe 2 to 4 recreated borrows for them to hide in. Would this be a good idea? I would make the "Ground" removable so that I can lift it to get to them if needed. and if so how much gap would I have between the borrow floor and the ground layer to give them room in? and how big should they be? I was thinking roughly like 30"x24" each allowing me to put in 2 or maybe 30"x15" allowing about 3? Also my adult ball like to curl up and sleep in high areas, so I was thinking a "fake tree" on one end with a couple hides inside the trunk, but again I'm not sure what size I should make these hides to be sure the snake has room to be inside and move around a bit to get out, etc. I will also listen to pros and cons to my ideas, there are probably factors I haven't thought of yet. Considering that I have just barely started making their enclosures, these ideas are still in the "pen & paper" design phase. If I put this in the wrong forum, I am sorry.
