So I had my cham for about 2 1/4 months and im still feeding him in a cup but i would like to make him hunt for the food and just let the crickets out loose, the problem is i have a glass terrarium (because it keeps the humidity better) with no substrate at the bottom just glass, but thats the problem since i have to spray his enclosure with water it just fills up at the bottom and i cant afford to add a drainage system, i clean out the poop and water once a week. since the water fills up i cant let the crickets out cuz they will drown and my cham will have trouble walking on slippery wet glass. I was think of putting a green 'reptimat' at the bottom so he and the crickets can walk freely, so what do you guys recomend?
