My cats started using this right away, with no issues. It was amazing how smooth the transition from litter box to CatGenie was!
The CatGenie is absolute amazing, and I absolutely love not having to deal with litter on a daily basis.
The granules do track a little bit, but no where near as bad as the litter did, and most of the time it gets caught on the mat, so I just pour it back in and wa-la! Problem solved. Very nice. Also, trimming my cats' nails really helped the issue.
The only thing I think would improve this product is if I could put a little door on it, so when the cats got in, it would be completely enclosed. My male cat loves to kick things up and around, and it would be wonderful if the door was there to keep it from getting kicked out.
Also - customer service was great! The CatGenie had an issue with the bowl rotating, and they got a new one out to us immediately, and talked me through getting it all fixed up. They were nice and knowledgeable. :)
