I have three cats so keeping the litter box(es) clean can be a real chore. I bought one of those expensive self-cleaning litter machines but for the price I thought it could have been done simpler.
I have already made this for the two very large litter boxes I use. I recreated this in a smaller version for this instructable.
Step 1: Items Needed:
Wire mesh fencing -- I'm not sure exactly what this kind is called (rabbit fencing, perhaps) because it's been so long since I bought it. It is very stiff and has about 1/2 inch squares. Be very careful when opening the bundle as it is under pressure and kind of explodes open! I wouldn't recommend chicken wire as it is too flexible and the holes are too big to sift properly.
Litter box -- for this type of project you'd probably want to use something much bigger like an under-bed plastic storage case. The one I have is 2x3 feet. (not the one pictured)
Step 2: Measure the inside bottom dimensions
This is an older, spare litterbox, much smaller than the ones I originally did this project for.
Step 3: Measure and cut the mesh.
Add up to 24 inches to the inside bottom dimensions to allow for the sides. This extra will fold down to make 6-inch sides.
Cut the mesh. YOU WILL GET CUT HERE! Those little prongs are very sharp and you will invariably get scraped or cut. Be very careful!
Step 4: Shape for cutting.
Turn the box over and shape the mesh to the bottom (length and width). This helps guide cutting out the corners in the next step.
Step 5: Cut out the corners.
These can be discarded.
Step 6: Begin to shape the box.
With the corners cut out, you can see where the extra 24 inches was added to form what will be the sides. 12 inches on each side.
Step 7: Bend the sides out and down.
I used the edge of my workbench to keep a relatively straight edge. Again, be very careful here! You still have a lot of exposed sticking points.
Step 8: Check the fit.
It's still a little big here, which is better than too small.
Step 9: Cut the corners if too large.
You only need to snip a couple squares at the bottom if needed.
