Thank you a lot for that link, thats a really really neat cage, she did end up using a shower rod or something for support over the bottom cage i believe? Thats essentially what im thinking about doing with the extendable long rod i had already from the medium cage lid, im not making it a multilevel cage, just an area they can go in while im cleaning the upper cage, so i dont believe ill need to make a flip side, especially because theres another entire grid level so i should just be able to lift the coro up and out of the bottom cage if that makes sense (i could also modify it to hold a piggy if she so happens to get sick) but i might look into that design of the dual level cage if i decide to get more grids later on
