Mango’s been on this litter for his whole life, aside from before he was adopted @9weeks. This litter is long lasting, can be used for 3-4 weeks before doing a full litterbox clean and change. Relatively low amount of dust for a clay litter. As others have stated, go for the bag not the box. The box leaks litter and is very frustrating. I believe for a short time this litter was sold for a very low price($10.49 for the 40lb bag) until it made the top selling cat litter list on amazon and then the price was raised to be similar with the competition. I’m not a fan of this tactic because my cat was accustomed to the litter and I simply took the price hit because I didn’t want to put him through switching litters as a young kitten that just got home. However I did enjoy the amazing price while it lasted and the price is still not tooo bad.
