No litter is perfect
In the world of cat litters, it's always hard to find the right one, because there's no such thing as perfect. Only your wallet sets the limit between qualities. This one isn't the best either, but after 14 years of experience, I can say it's truly premium. It instantly traps odours. It clumps rock-solid, doesn't fall apart, and doesn't get dusty. The downside is that compared to the usual litters, the grains are much bigger, so it runs out faster, and if you don't keep topping it up, it sticks to the bottom of the tray.
