We recently got a panther chameleon and we have a screened cage at the moment that is hovering on the lower end of the humidity scale. I have implemented a fogging system, but obviously the screen is not helping hold that in. I think I'm going to partially cover the three sides, leaving the bottom 6 inches open, and the entire front. I'm also considering putting an under cage style heater pad on the tray of the enclosure. My thought is that I can place it under the live plant that I have inside and it will slowly warm up the soil (which has the dripper consistently watering). I figure this should help increase humidity, maybe add a very slight amount of warmth, and help the plant from becoming too waterlogged. Also, I have created a tray on the bottom of the enclosure so it will hold water and prevent it from draining onto anything else, instead of just the sheet of plastic that was included. Has anyone done this style heater or have any other thoughts? Thanks.
