No one wants to scoop their cat’s litter box. Bacteria and germs can form on scoops, leading to a less sanitary environment. The Omega Paw Self-Cleaning Litter Box is the modern version of the old litter box. After your cats relieve themselves, you roll the box towards the right until the top closed section touches the floor. This movement allows the waste to be left in a pullout tray for easy disposal and the clean litter won’t be wasted. $35. BUY.
