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)
