I use the crystal litter and I love it. I used to use this natural pine litter and that stunk really bad. I never smell anything now that I use the crystals. Its easy to see where the pee is and if it builds up in one spot, I'll usually scoop that part of the litter out and add a little more. I only do a full litter change about once every month or month and a half now. I scoop poop about every other day though.
