Ive been trying out Skoon Cat litter. Im on my 3rd month now.
I can recommend it. The litter is like small white light-weight rocks.
The urine is immediately absorbed and does not smell at all. There is absolutely no buildup of it at the bottom either.
It comes with a special pooper scoop that has larger holes.
If you scoop daily you will should not have any kind of smells with the solids.
Tracking is reduced because the litter is not as small as normal litter particles.
I still keep an entire large litterbox filled with my kittys' other litter brand because cats are creatures of habit & do not like change. I figure Ill let them decide what brands they prefer rhe most without upsetting them too much. So far all 3 of them use both brands equally now.
Here is the webpage with videos & more info if anyone is curious.
