I have used one bag and would not use again. Some people must like it but it is a no from me. I found it smelt very quickly and you use more than say with a clumping litter as it spreads further and goes yellow. At least you can see where it’s spread to. I used a very expensive brand that is supposed to be very good, can’t remember what now, thinking you get what you pay for. Maybe a cheaper brand would be better but I would never try one again. The other thing it is very sharp on their paws and they weren’t as keen to use it. I use Natusan now and it is brilliant, though expensive. No smell and clumps very well.
