Things You'll Need:
- Standard rectangular litter box
- plastic tub with plastic lid. Sides must be over 16 inches tall (40cm), the litter box must fit into the bottom of the tub.
- A strong kitchen scissors or tin snips or jig saw with wood/plastic blade.

Step 1
Dog-proof cat litter box.Find a plastic tub that has an attractive color that will transmit some light. White, gray, light blue and pink are good choices. Make certain that your litter box fits into the plastic tub with enough vertical clearance for your cat to be comfortable. If you would like to keep your litter scoop in the box, make sure there's enough room.
-
Step 2
Draw a hole on the lid.Trace a circle big enough for your cat to be willing to enter into the top of the box. Anywhere near the middle will work. You can trace a plate to make it perfectly round.
-
Step 3
Safely cut the hole.Carefully cut the circle out using a tool that you feel safe with. Do not use a utility knife or box cutter as they can snag and lead to severe cuts.
