This litter has good odor control, I have 4 kittens using it and the smell is pretty good compared to other litters. One bag lasted about 3 weeks with 4 of them using it which is the longest lasting litter I have used and its a very good price for the product. The only downside is it expands and becomes sawdust when exposed to moisture, so at first I accidentally over filled the trays (was at the same heigh I normally use) but because it expanded the tray soon became full and they started kicking sawdust everywhere. As long as you're aware of over filling you wont have a problem. Overall – I'm Impressed!
