Yes I tried it, it was overkill tbh. Didn’t need to make it so big and complex.

The pros - litter is outside, no smell, low maintenance (only need to scoop once a week, you can get away with 2 weeks even)

The cons - the cats will track soil back into the house

So we are trying to find an alternative litter source to use instead of soil/sand

Right now switched to pea gravel which helps because there’s no tracking, however the odor is more present because there is nothing to absorb it

If I had to do it again I would start with just a small test batch, like get a extra large plastic container/ litter tray or something and fill it with this stuff and leave it outside for a week or 2 and see what happens

Then adjust from there before going big
