“We tried the Silicia first, and noticed that we had a lot less "waste" in general, but the big pieces were all over the floor, and if you walk on socks and step in them, it hurts. But because we liked having less "waste" we decided to try the fine-grain. And this was the better option for us. It is a little bit dusty when you are doing the scooping, but it can't be completely perfect I guess. I would definitely recommend it, if you can live with having a little bit more dust near the litterbox”
