Catit Design SmartSift is an automatic litter sifting system that takes the chore out of litter maintenance. Simple yet innovative, SmartSift’s litter sifting design does the scooping for you. So you can say goodbye to your litter scooper!To refresh the cat litter pan, all you have to do is pull the lever-it’s that simple. It’s so easy and mess-free, even a child can do it.
