Might start a separate thread with that question, as I think some here do that exact thing- so they can tell you how or where they got theirs. Have you looked on sites for herp supplies? Like on Bean Farm or Reptile Basics? Or just googled "safety cage for CHE"? I think a lot of members use RHPs, actually. I don't though, so I can't advise you on that. Enclosure upgrades are both welcome & nerve-wracking...but you'll get it all figured out.
