I'm using Soft Sorbent for the cage and using Yesterday's News for the litter box. I've been picking up poops from the floor and into the litter box and tossing some of them out too to keep them out of the SS. The YN is getting pulled out and mixed, should I take that out of the cage and toss it and keep the SS from getting in the litter box so they stay distinctly different? Or is a little mixing okay?
