I love having the autoship! It makes life so much easier. The savings involved plus the free shipping is a plus, too! We have two cats, an 18-year old Bombay which has some health issues, and a 6-year old. The 18-year old has chronic diarrhea, despite the antibiotics and steroids. We go through product a little faster than the norm because of her frequent usage and the crystals sticking to the eliminations, but it is still worth every penny!! Life in the household would be miserable for everyone without it. I wish there was a subscription with a little more product available because of our situation, but for now we just order a few extra boxes of Granules or Sani-Solution every once in a while to keep on hand so we don't run out. I recently contacted the company to have them send out our autoship a few days early, and they were wonderful with it!
