No. The Simply Clean™ Automatic Litter Box has no exposed moving parts, and the litter bowl rotates at a rate of one rotation every 1½ hours. It is whisper-quiet and will not startle or disturb your cat.
Yes. Since waste is continuously sifted and moved to the covered waste bin, you will notice a considerable reduction in odour compared to other litter boxes. To reduce odours even more, you can add some fresh litter and baking soda to the bottom of the lined or unlined waste bin. The carbon filter in the conveyor hood will also help to reduce odours in the waste bin area.
Depending on the level of use and how many cats you have, we recommend that you empty the waste bin when it is nearly full, or every other day, to better reduce odours.
