This homemade sifting cat litter box is very easy to make and works nicely with pine or wood pellets which are both better for the environment and save money.

Make a Sifting Cat Litter Box
If you are switching to an eco-friendlier cat litter system like wood or pine pellets, you will need a sifting cat litter box as well.
These pellets breakdown into sawdust when wet. With the sifting litter box, the sawdust falls into the lower chamber. Any solid waste is removed with a scoop.
Because this litter is not clumpable, it lasts much longer than traditional clay-based litters, saving a lot of money.
To make the box, two same-size plastic bins are stacked one on top of the other.
The trick is to choose bins with side handles: these create a gap between the stacked bins, leaving room for the sawdust to accumulate.
The only DIY part of this project is to first drill holes in the base of the one of the bins.
I used a 1/4-inch drill bit and spaced the holes one inch apart.
To avoid cracking the plastic, place a scrap piece of wood underneath the bin and push the bin down against the wood while you drill.
If it helps, you can draw guide marks on the wood to keep the drill holes evenly spaced.
