I've tried them all. The ones that claim to control odor stink while I'm scooping and the dust flies into my face. I can't imagine a little cat pawing in the litter to make a place to relieve themselves while the dust is flying into their face and nostrils.
Special Kitty has no dust and it soaks kitty's stuff up really well and there is no odor lurking around the house!
And the really best part about Special Kitty is that it costs less than the other brands.
