I have for auction or sale our nearly new litter tray. It is a BossCat model. After only 3 months our cat, a Maine Coon has already grown out of it. It has been a wonderful toilet, a great system. Easy to use and very easy to clean. It is in immaculate condition, and has been thoroughly cleaned. It uses pine pellets as the litter, which break down into dust, which are then discarded, after the solids have been removed. A great system. Virtually no odour. The size is 50cm x 40cm and approx. 18cm high(the splash guard) Pick up Maranui St area. Please ask questions and I will try to answer them. The asking price is very reasonable, as I have seen them advertised for $99, which I paid. Please note, the bag of pine pellets does not go with the item as they have been used, but I can give you some pellets to start.
