I knew I should have checked this forum first. Just posted the same topic in "general." I'm having great success with the "pearls." My new kitten loves it, and even my 10 yearold has adjusted to it fine. I haven't noticed any dust; at least a lot less than the scoopable litter I have been using. As for cost...I find it to be the same cost or less. With two cats, I've been buying 4 8lb. boxes a month. At 7-8 dollars a week, it ends up costing me a lot less with the pearls. And it weighs almost nothing. A big break! I was having the worst time with tracking. Litter scatter embedded into the spaces between the boards of my 200 year old floors! Having to "dig out" the litter with a knife every day! There also seems to be virtually no odor after scooping the poop!
