I really wanted this Scoop-free self-cleaning litter box by PetSafe to be the winner for my cats but only 2/3 will use it at this time. We still do 2 other regular litter boxes. I really like that it is self-cleaning, dust free and you can just kind of forget about it for awhile. You do have to buy special litter trays and my stores do not carry them near me so have to get online. Overall, it works well and would recommend.
