Another tip - when you use the foam, put down a thin layer and then let it set before putting on the next layer. I have 3 Large Clearside Dragonstrand cagees, and inevitably we try to do too much foaming at a time and it bulges out the side. For my cages I use the silicone, then use the foam (typically I'm foaming in pots for plants), then a layer of silicone and the coco fibers to cover it all. I let everything air out at least a week or 2 before putting in a chameleon. I'm doing my third cage currently and if we ever finish it I'll make a photo blog how-to guide (though I've been saying that for a year, but this time I really mean it!)
