How to Make a Cat Litter Box Out of a Rubbermaid Container?

Material required to make Rubbermaid litter box.

Step 1

Simply take a paper, then cut that into 18 cm wide straps. This will be your template. So keep that safe; you can also use this template later on too.

Now, use this and try to mark the side of the box.

Step 2

Take a marker pen, measuring scale, and the paper template you made earlier. Now, make a 4 cm horizontal line at the bottom of the box.

Step 3

It’s time to do some strength work!

Take your soldering gun and cut the marking that you made earlier. Make sure to use a flat-top soldering gun for cutting the plastic. But, if you don’t have that, don’t worry. Just make sure the plastic doesn’t break while soldering. It’s like when you cut the plastic box with a saw, the plastic splits. So, to avoid those cracks, try to do it gently.

Pro Tip: If you don’t have a soldering gun, you can also try a saw to cut the plastic. But make sure you cut it slowly and with a fine blade. Large Rubbermaid containers are tough. So make sure the cutting part is done smoothly.

In case you are using a saw, make sure you don’t rapidly cut back and forth. Also, if cracks occur, then you have to cover that with plastic packing tape!

Step 4

Now, keep it on two sides. Once the entry point is made, and the plastic is removed, this is when you have to do the filing! The edges are sharp, and it can hurt your kitty while using. So, to avoid such mishaps, always smoothen the edges.

If you are making a Rubbermaid litter box for your kittens, you have to cut it shorter than 10 cm from the base. In this way, she can easily use the litter box without litter being wasted!

You can make the entry point a bit narrow if your cat is slim. Furthermore, keep the measurement 7″ in that case.

Now, your Rubbermaid cat litter box is ready for use. Add some fresh litter and place it wherever your cat likes!
