Terrible black at first smells nice after a week all the dirt smells the urine does not flush they sit down and stick to the walls of the toilet bowl

I rate it with 5 stars because this specific pellet smells wonderful and never has that awful urine smell like the gravel.
It is suitable for long-haired cats because it doesn't stick to their paws like the gravel of the gravel...
Also, when it gets wet, it forms small balls that are very easy to collect.... The only disadvantage is that even in big cities I can't find it except in a specific pet shop...
