One of the best litters I have tried in recent years. It clumps immediately, doesn't get muddy, and doesn't smell. I have a large cat and her litter box takes about 1.5-2kg of litter, since it is cleaned at least once every 1-2 days and the litter box itself is cleaned at least once every 1-2 months. I have never had a problem with odors whether it was inside the house or outside. In addition to scented options (baby powder, lavender, and orange), it also comes in unscented "antibacterial" and "carbon" varieties, but since I have used them, I don't see any significant difference in their performance (nor in their price, of course, there is not much of a price difference). So, choose whether you want a scented fragrance that you like or otherwise I would recommend the plain one.
