Ultimately, I only purchased one bag to help rule out any problems before rushing my cat to the vet. She had peed in my husband's shoes twice within a month or so, but was otherwise acting totally normal. We were assuming it was not enough play time, and the litter ruled out any other health concerns.
The bonuses are that the litter has great smell/odor control and very minimal tracking and dust. I also appreciate having to scoop only the poop. So, one bag turned into a subscription when I tried to switch back to a more traditional litter. I was frustrated with not being able to see her urine color which had really grief gauge on her water consumption. I won't go back and have had the subscription for close to a year.
Bottom Line: Yes, I would recommend this to a friend
