Clumps, doesn't smell
My cat does pee a lot on the edge of the litter tray, so it sticks there of course, but otherwise the litter clumps really well and doesn’t fall apart quickly. There’s no cat toilet smell and it’s completely dust-free. Yes, some small bits do get tracked out on the paws, but that’s happened with every litter I’ve tried so far. An old piece of carpet as a mat helps with that. The price is really steep, but I haven’t found a better litter yet.
