This is the THIRD CATGENIEI have purchased. One in each home. I talk to no one with a cat without telling them this product will change their life and their beloved cat's. If there at my home I make them watch a complete demo to prove what a wonderful item it is. You can leave home for days and not worry that your litter box is clean and healthy. With dome you see nothing and smell nothing. The VIC club purchase is an EXCELLENT saving of money and time. I cannot say enough about how wonderful this product is!
