As a vet nurse, anything to help make monitoring my pets health easier I was willing to give it ago. Previously, using regular crystals, I was only getting a couple weeks at best from a bag, but with Fit litter, I've been getting full month from each bag. The super fine crystals dry out faster and hold the smell much better than the larger crystal brands.
I didn't think it would actually last a full 30 days, but now I've tried it for my little man and, we love it!
