Query: cat litter box

It does not work and is messy, leaks cat litter and does not get out all of the dirty litter, you have to go over with a scoop, not for multiple cats, poor design because the grate that sifts the litter does not get the smaller clumps, the box is very big and so you cannot have as many in the same spage. expensive for not working and now that I have tried it out, I cannot return it. If it works best with a certain kind of litter, then they should have recommended it. When you have as many cats as I do, you need good products, not one that waste your money. I would have paid more for a box that does what it is supposed to do - but to pay 2x what a regular box is and then have it be a waste, really is not very nice. I hope to discourage others from wasting their money.Omega Paw Self-Cleaning Litter Box, Pewter
