The most expensive and the best litter out there.
I have two cats with two litter boxes. Cleaning just poops out of box,the rest lasts for three to four weeks. No smell or odor! You can damp solids in the toilet,since the litter is organic minerals.
Then you change it completely and so on. No hassle!
I am willing to pay money to be able to not have any dust or chemicals to breath with.
Finally I found the right thing! Trust me! You won’t be disappointed! Highly recommend!
