Those are very nice links Brenden, and there are many ways to do the job.
This is the way I prefer because it makes it easy.
After the cats start to eat, they will will poop little pellets called frass, these have to be cleaned out of the box everyday.
Since the box is lined with paper it makes it easy to clean, it just rolls off, and you can add a new paper if needed.
You don't need to give them water because the leaves contain enough moisture for them.
Just give them a few leaves everyday as they need it.
I will talk about it more later.
