I bought the Tuxedo package for my kitten Annabelle almost 2 months ago, and we both love it! As a child, I cleaned a traditional litterbox by hand for 10+ years and it was awful. When I got my kitten, I knew I didn't want to clean the litterbox by hand again. I bought a rake-style self-cleaning litterbox from another company, but I was very disappointed with it. The poop would actually get stuck in the rake and cake on, which smelled terrible! That never happens with the CatGenie due to the unique design. The cat acceptance guide was very helpful, and Annabelle adjusted to her CatGenie within 24 hours. The Tuxedo package is perfect because it includes the sidewalls and hood, which prevent Annabelle from kicking the granules outside the box when digging.
