Disposable/Temporary Litter Box

Step 4 Putting in the Plastic Bag

Now i just used a plastic bag from a random grocery store. Lay the bag flat in the cereal box and then tape down the sides that hang over the top. If they're too long (like on the handles) you can cut them with the knife, and if you want to decorate the litter box you will need to cut them shorter. Tape it to the box all the way around it.
