Catsan Smart Pack is the first insert pack for the cat litter tray. Thanks to its unique functionality, it can be easily put over the edges of the cat litter box and thus provides a pleasantly clean cat litter tray. To make your cat feel comfortable every day. Under the Catsan hygiene plus litter there is an extra absorbent dry fleece that actively absorbs the liquid under the hygiene litter and securely locks in. The odour binding becomes even safer and the litter stays significantly longer for your cat. Just as she likes it. In addition, the toilet floor remains pleasantly clean and saves you a complex cleaning when changing the litter.
