This plastic container should be included with the main unit. No one wants cardboard. And sure not for $70.

The plastic bin is so much better than the cardboard. Just replaced my 2 year old cardboard one, the original that shipped when I first bought the unit, and am mad at myself for not replacing it sooner. It was so beat up, tape holding it together and the smell... omg, the smell. I didn't realize it was that bad until I had pulled the hole thing out. At least with the plastic, I can sanitize it every once in a while. Would have been a 5 star, but the price is a bit absurd for what it is, but I hope to get longer use out of it.

My cats enjoy using their new cat box. Works great! Hopefully it lasts!

I prefer the plastic base and cover because I have Maine Coons and once win awhile they sit on the box…when it was cardboard the whole thing caved in. This is much better.

Works great, cats can't destroy it like cardboard and the plastic waste bag fits easier and more securely than on the cardboard one.
