I followed this tutorial (http://ball-pythons.net/forums/showt...my-Ball-Python) for making my own set up; don't get me wrong I think this set up is awesome but the only form of security is a clasp at each end and the corners and sides can be pushed up. My ball python escaped and I found her and put her back (that was this morning) and she hasn't escaped since then but I put some heavy books on each corner

This is not very convenient as I have to remove each book if I want to open the cage; is there any other way of locking this container?

Thanks
