while perusing the KS dart frog site (no, I am not leaving the cham's behind, just need something to fill my vivarium and have always been intrigued by these stunning creatures) I was on this guys site and he has a VERY comprehensive page on building a cage for his veiled cham! He has nearly 2 dozen photos from the floor up (literally), part list, etc.. So any of you looking to build a cage you may want to check it out:
