This litter is supposed absorbed all the smells that qu'ele done well but it created another! Because even if they pick up the droppings can we filtered the area contaminated by the urine and so even if the urine does not smell, if the litter! Especially that according to the indication on the box on the left is supposed to 4 weeks! I confirm the other comment that indicates the odor concerns. I much prefer the aglomerante litter.
