Lightly used. I love this litter box. It is extremely quiet and rotates quickly. The disposal container is large and with our four cats I emptied it only every day and a half. It came with deodorizing blocks which we never used and we could not smell the litter even standing right next to the machine. Our problem is the number of cats we have. We have four cats and the litter area needed to be filled 2 times a day because of this. The large size of two of our cats and the fact that we have a cat with diabetes does not help. Ideally I think that it would work great for a household with 1 or 2 normal size cats. New it sells for $700 and we are asking $450. If you are interested please call Darlene at 204-823-3187.
