This invention has made such an improvement in our daily lives! It's keeping our home fresher with the automatic cat activation cleaning cycle for our 2 cats. The cats adjusted to the CatGenie on the same day. I put it in the same location as the original litter box. No more trails of clumping cat litter throughout the house. No more daily scooping of litter. These granules track but nothing like the clumping litter. I put a Black Hole Mat (Beige Color) in front of the CatGenie and it captures most of the granules. Quality materials and a product that has really enhanced a busy lifestyle.
