I have a Crane Teardrop cool mist humidifier (made for people) hooked up to PVC pipes that take the mist directly to the cage. It's on a timer to be on for 30 minutes every other hour. My cage has never been very moist after it's been on and it dries completely between timer sessions. But it helps tremendously with humidity, especially in dry climates. Mine shed so much faster now with it. You want a cool mist humidifier, not a warm mist - those give off steam that could burn your cham. My panther will actually go sit on the the branch right in front of the mist so it blows on him directly, especially on warm days. Then they also have droppers for drinking.
