Bests & Worsts Reviews from Amazon

FABULOUS litter box! Works great if you follow the advice of other reviewers by keeping the sifter tray IN BETWEEN the two litter boxes. When it's time to clean the litter: -Lift up the box currently being used (1st box). -Pour it into the 2nd box underneath (with the sifter already on top of / inside of the 2nd box). -Put the 1st box down. -Lift the sifter tray & gently shake. -Dump the contents into the garbage can. -Place the sifter back down on top of / inside of the 1st box. -Then put the 2nd box (with the now clean litter) on top of the 1st box with the sifter & you're good to go! Doing it this way prevents the sifter from becoming clogged with wet cat litter in the process of clumping. Other accessories that I recommend to use along with this box are the Petmate Ultimate Litter Scoop 22972 (for quick clean ups between siftings) & the Vivaglory Large cat litter box mat to prevent the litter from tracking all over the place.
