Instructions
Purchase a litter box. One type that can help minimize stray litter has a cover that snaps onto the bottom section. Some have swinging doors that can brush off litter once your cat leaves the litter box.
Place the litter box in a larger cardboard box if you have a regular litter box without a lid. This can help if your cat scratches the litter over the side of the box, preventing the litter from landing on the floor.
Pour litter into the box until it covers about 2-inches deep. Some long-haired cats prefer less litter. Keep in mind that most cats like the fine-grade litter since it has a softer feel. Use this type of litter for scoopable litters. Remember that this type can also make more of a mess.
Position a plastic-ridged mat in front of the litter box. This can catch litter stuck in your cat's paws once it's done using the box. If you don't have a mat, an old rug or blanket can work just as well.
How to Keep a Cat From Kicking Litter Out of a Litter Box
Once a cat uses the litter box, you're usually left with two issues: cleaning the excrement out the litter box and dealing with stray litter all over the floor. Since the litter box has to be cleaned by someone or a self-cleaning system, you can focus on limiting the litter found outside the box.
