The litter that can be changed in seconds! Change the litter... lift the bin, fetch the shovel, scrape the clumps, push the cat who comes to monitor your work just at that moment, empty the bin into another container while you clean the first one, recover with shovel all the clumps, clean the box a second time because the cat has just come to do its business there before you have had time to put back clean litter, then put the litter back in the right box and add more. .. Or, get the easy-to-clean sieve litter box and: Lift the first box, which contains the droppings and the still usable litter. Shake it gently over the second bin. Throw away any droppings that remain trapped in the first bin. Replace the first tray, now empty, under the last one, turning it over beforehand (so that the sieves fit together in a staggered pattern). Add a little new litter, if the quantity of remaining litter seems insufficient to you. And it's done ! Characteristics of the easy-clean sieve litter box: 3 stacked boxes, 2 beige and 1 brown.
