I have noticed with this season change, the humidity has dropped in my boy's cage. It may also be due to heaters on in the house sucking the moisture out of the air. i have a fogger and hand sprayer and use both daily. I also have two sides, the back and right side of his 2x2x4 reptibreeze sealed and keep the fogger on the sealed side. I mist the plants in the morn and afternoon and if the humidity is low i mist the top screen below the basking lights as its evaporation will increase humidity too. if you keep a fogger on thru out thenight, keep it low and in an area where your cham cant sleep under it. my cha!m loves sitting directly under the fogger but got URI as a result. so i learned the hard way. The primary reason why humidity is crucial for chams is because they get much of their water by the moisture in the air. my cham never drinks off of leaves or anything and I recently took a small eye drop bottle, cleaned it out, filled it with bottled water and tried dripping water on his mouth. I am shocked at the response. He not only opens up and tongues for more, he actually tries to suckle it like a bottle. Cant wait to get a video of this. He just loves it. Seems to do better while he is upright in my hand. good luck i hope you can figure it out. I live in calif so winters get dry.
