I really like this cat litter. It definitely lasts for a month, I was a little nervous about that part because before I switched I was buying cat litter more often, but some of the time I even end up with extra at the end of the month. The unscented version is nice, it doesn't have that cat litter smell, it does have a slightly woody scent to it when you first pour it out of the bag, but its not unpleasant at all and doesn't stick around in the room. My cat has no problem using it, she didn't mind the switch over at all. I started using it as a more ecofriendly version of cat litter, but it stands up as a great cat litter without even taking into account the environmental benefits, which just makes it even better.
