Overall, it was easy to put together. The package arrived safe with no damage. The doors were not lined up good at first, but I left it like that and after a couple of uses it sorted itself out. I also purchase the catching cat litter tray. It helps reduce the litter from getting to the floor. I still added and extra layer of carpet I had left over just to be safe. I also like the liner that comes with the litter box. It does not come with the filters but I personally don't like filters. It looks very nice and better than a regular cat litter box being exposed. My cat had no trouble adjusting to it and I even moved the litter box to a new location.
