Coming from a similar (catmania) I have a lot of positive things to say about this litter.
Firstly, it is 12 liters, which is 10 kilograms, while others are about 10 liters, approximately 8 kilograms.
Secondly, it is coarser compared to the other one I had, and it clumps very well, especially in the first few days.
Thirdly, with thorough daily cleaning, I can say that it lasts me at least two weeks (half a bag, 5 kilograms)!!! Of course, this also depends on how many times your cat goes!
In general, for me, it is a value for money litter, both in terms of quantity and clumping. Towards the last few days, it loses its scent, of course, and it creates a little more dust when the cat comes out, always based on my cat's usage!
