Every chameleon that has ever been in one of these cages seems to wear out their nails and they fall when climbing on this screen. I move them to the large Zoomed enclosure and they have no issues. The zoomed enclosure has a lot better and a more sturdy screen. What is the deal w/ these aluminum screen enclosures? I have weaved vine and lined the top of the enclosure and on the sides the green plastic fencing ( wich looks tacky I think). Any recommendations on these enclosures? Thanks for the advice.
