“Stinky's human rates kitty litter on three aspects: odor, clean up, and tracking. She appreciates not dealing with clay clumps, and the stuck on litter at the bottom of the box. Also there is zero odor, except when Stinky decides to leave his fresh poop on top as a reminder to his human to clean up his $#!t. The silica does track, but it doesn't stick to human children feet like regular clay litter did. Overall, we are very happy with KPC, and I can't wait to throw the entire box in the trash and see the prints on the next box.”
