I just bought a few boxes of fresh step cedar. I used it to fill up the booda dome in the computer room. This seems to be the room with the biggest odor problem- we are usually pretty lucky with this. I think it is b/c we use this room the most, and one cat in particular likes to do his stinky business and not cover it! Normally I use fresh step regular or w/ added crystals, arm and hammer or tidy cats. It smells really nice and natural so far and doesn't seem to be as dusty as regular fresh step. Anyone tried it?
