All over the house!
I love the fact that this litter hides smells, clumps, is flushable ... but i HATE the fact that it tracks literally all over the house! Alsdo, since I have a Bengal cat, who loves to 'stir' her water in the bowl (Bengals like to drink running / moving water), I have to change the water extra frequently as the litter sticks to her paws and ends up contaminating her drinking water! However, I keep on using it, because it really is good in all ways other than the tracking.
