I'm planning on making my own fleece cageliners and I'm going to be using a layer of fleece, Zorb and then Procare for the bottom layer. I've never used Zorb before and am wondering how many layers I should use? I know that it's super absorbent, but I'm wondering if it would be better to use 2 layers instead of a single layer, for added absorbency and also for a little cushioning so the lining won't be so hard under the piggies.

Thanks!
