This is how the product works. First, you put the wire mesh on top of your litter box. Next, you put another litter box on top of the wire. Third, you clamp all the pieces together. Fourth, you flip it over then you shake it a little to sift all the good litter through the wire. Fifth, you take the clamps off, then you take the top and the wire off and in the wire is the poop. Last, you throw out the poop, also you have clean litter. Comes with free air freshener! Only $19.95!
