text: This box has made my litter scooping job so much easier! At first I had the litter directly on the sifter which caused urine clumps to clog the holes in the sifter. I wasn't happy so I read reviews. One buyer recommended putting the sifter BETWEEN the 2 solid pans, when cleaning lift the top pan, dump it onto the pan underneath with the sifter on it, lift and sift. This works like a charm! I no longer fear scooping litter pans!
