I don't know who had it on here, but someone was using a sort of glass bowl... it looked like a fishbowl laid on its side, but then imagine the opening on the top. And the opening had scalloped edges. It was basically a very large, squat glass jar. I thought that was so cool, because you can see through it, not like the plastic dust house I have and many people use.
I usually put 2 inches or so of dust in , and sift it to get poops out, but my boys don't pee in there, so that's why I reuse a lot. If your chin pees in the dust, I would use less, so you won't waste as much.
