One word first: "dust" does not mean "free of dust." The Klum litter consists of the standard material and bentonite is quite finely pulverized; Prerequisite for good "lumps". Nevertheless, the development of dust is limited. The bags are quite stable, the carrying straps do not tend to tear. My three seniors who are not in any case particularly picky cat litter, have adopted the stray without Mäkelei. Moreover, the two 15 kg bags delivery by post, despite quite favorable. I will go and stay with it.
