I use the + HYGIENE Catsan long and 'am satistait. Cats apparently also. By against the packaging 20 l. seems totally abhérant. The position of employees and subscribed clients are not all weightlifters or movers! Moreover lessacsde 10 l. corresponded to the dimention litter. In short, I think stop my subscription for this product and regain for bags of 10 l. AMAZON if returned to this conditioning that is still, fortunately, super market.
