We have been forced to use this litter for 2 weeks while our cat is radioactive because of radioactive iodine injection to treat (cure) her hyperthyroidism. For that period we must flush her wastes daily and this was the only flushable litter available. It hardly clumps. For the most part I've been struggling with crumbly wet litter. Also, no matter how often I clean the box there is a pervasive urine smell in the vicinity of the box; so much for the claim that "wheat enzymes naturally eliminate odor." As for tracking, it's scattered all over the place. I can't wait to go back to Fresh Step, with which we have never had a problem. I'm just grateful that we haven't had moths and maggots as others have.
