I have 2 of these PetSafe self cleaning litter boxes. Both were used maybe once, the cats were very uninterested in using them so instead of letting them collect dust in storage i'm hoping that someone will get a good use out of them. The way the Litter box works is the dish at the bottom that holds the litter continuously turns slowly enough so that by the time the waste gets to the lift it had time to clump up. Both in very good condition 10/10. No box but i keep them wrapped in plastic bags. I originally paid $150+tax each, I'm asking for $100 each or $150 if you buy both litter boxes. PRICE IS NEGOTIABLE! Pls message me on here for details or to come by and take a look at them. They are too big to lug around so you will have to come to Sherbourne st and Earl st (Downtown Toronto close to Sherbourne and Wellesley) ONE WAS SOLD, THE OTHER STILL AVAILABLE.
