Litter invariably sticks to your cat's feet and is tracked on the floor. Some cats kick the litter with their back feet and scatter it. This isn't a problem with covered boxes. You can get one made especially for litterboxes or use rugs, carpet remnants, the bottoms of cardboard boxes, etc. Having a small handheld vacuum cleaner next to the box is also handy.
Scoops come in a wide variety of shapes and sizes.
A sturdy plastic scoop is easy to use and clean. Some scoops let you attach a plastic bag so that clumps are scooped and dropped into the bag at the same time. It pays to get a sturdy scoop because litter is quite heavy and poorly made scoops will break. Look for scoops that are rounded rather than flat because litter clumps tend to slide off of flat ones. You just need to make sure your cat doesn't feel trapped and refuse to use the box.
