Winston, don't let the name fool you. I bought this when Vlad was still a kitty. I found it to be terrible at odor control. And if I found it bad when I only had one kitten, I don't even want to imagine what my apartment would smell like with 5 grown cats.
I use Swheat Scoop and scoop once a day. I change my three boxes every two weeks, and refill in-between. When I can, I buy the Multiple cat swheat scoop, because it does clump faster and firmer. Swheat scoop is about $10 for a 14lb box, so it's not cheap for me, but so far it's the best thing I've found at keeping odor down, and my cats are okay with the way it feels. It is also dye and chemical free, so I like that.
