This is the closed cat litter box that avoids unnecessary waste of litter and does not need hygienic bags: thanks to the practical sieving system it is equipped with. It consists of a lid and two bottoms: a standard one for collecting and dispensing litter and a perforated one which works as a sieve for clotted litter. When you have to remove the old litter tray, just lift the perforated bottom and sift the litter that will be separated as follows- in the sieve will remain the clotted litter to be thrown away while in the standard bottom you will have the still usable litter to be replenished. The toilet box is resistant and durable, made of thermoplastic resin, easy to maintain as the upper part can be opened thanks to suitable fastening and unfastening side clips. It is complete with a swinging door that helps to retain smells inside, obscured to ensure privacy for the animal, and two activated carbon filters (also available as spare parts) inserted in the ventilation grills placed on the lid, essential to neutralize bad odours. On the roof, a comfortable handle will allow you to place the toilet box where you prefer. For a correct functioning of the sieve, it is recommended to use only fine-grain litter such as sand and not chipboard or coarse grain gel bedding. Finally, we recommend using biodegradable litter, to protect the environment and limit environmental impact, and which also helps to contain odours. Choose the model to suit your pet’s size.
