I've tried many kinds of litter too. I used to use Swheat Scoop but it seemed too dusty to me. I've now been using Ever Clean Unscented Extra Strength Litter. It clumps very hard and the cats seem to love it too. It's kind of expensive but if I buy it at Pet Club it's reasonable and it lasts a long time too. It comes in 4 different formulas. The scented one is probably better for odor control but I didn't want to buy this one because sometimes the scented ones will be too strong for my cats noses and they won't like them. Good luck.
