What a nice, sturdy cat litter box! I selected the grey unit. The best part of this unit is the scoop being attached to the unit. The unit is very roomy and the box that holds the kitty litter is not attached and is easy to remove. It also has a litter tray to catch kitty litter that falls off your cats' paws. It has two handle holes to grasp and carry the unit. Buying this unit will not disappoint!
