I've tried many many natural and scoopable litters and now I'm using unscented litter. My cats also prefer this. It seems like all of the new and improved formulas are just too strongly scented these days and if I think it's too strong then I know it's even stronger to my cats.

Ever since I had peeing issues I've switched to Dr. Elsey's Ultra Precious Cat Litter in my uncovered boxes and I also use Premium Choice Extra Strength With Baking Soda Crystals in my 2 covered boxes. Both are unscented and clump very well and there's very little dust. I scoop twice a day and there's no odor unless one of the cats has just recently done a big poo.
