My husband and I have been using this litter exclusively for over a year. We both hate to clean the box, and when I was pregnant, sometimes their box didn't get cleaned for almost a week. They seemed to handle it better with this litter than a previous version of tidy cats clumping.
Sometimes the urine clumps fall apart, especially if the cat(s) tend to urinate in the same spot before you get a chance to clean the box. However, I think this is the case with most clumping litters, not something specific to this brand.
