yeah, with those species, they really need to be in a screen cage (unless 4 months or younger). It is best to do as much research on the proper care for a chameleon is you have never had one before. They need a lot of special care but once you get it down its pretty easy. Jacksons are a montaine species (meaning they live in mountains) so they need more humidity than the average chameleon. All chameleons need a couple spikes of high humidity throughout the day. Most people either handmist or use a misting system, such as the Monsoon or a mist king. Also chameleons can't see standing water so the misting is a source of hydration as well as maintaining the humidity.
