This has been a game changer for the litter boxes. With 3 cats and kids I have a hard time remembering to scoop everyday. This litter box does it for me. So amazing! I love that it is corded so I don’t have to rely on batteries. The litter is excellent quality and I love the cardboard tray liners. They are so worth the money for the quality you receive. My cats have not had an issue adjusting to this litter box at all. It’s silent when it’s working and everything gets sifted out. 10 out of 10 for cat owners!
