I have finally assembled the cat genie and I am loving the relief it gives me from having to think about cleaning the litterbox. I watched it during a cleaning cycle and it truly is amazing how it works and it works perfectly. One of my cats sniffed it, realized it was a little different but went "oh well" and happily went inside it. My other cat is finnicky and does not appreciate it for the time being, but hopefully it will grow on her as today is my first day using it.
As for setting it up, the t-adapter provided may not fit on your toilet so you may need to go to Home Depot and get an adapter and universal stainless steel braided connector (as I was advised upon calling CatGenie customer service. However, after that was complete, setting it up was a breeze. In this package specifically, I wish it came with two boxes of the granules, so I will be ordering one more soon.
All I can really say in the end is I love it!! It's definitely at least worth a try for every cat owner!
