I had to write because I love the cat genie!! I was so skeptical about it, and I do consider this to be a bigger purchase. We installed ours 1 month ago, and have not touched it since!! We put it in the laundry room (far away from our cat's old box) I put her old box next to the cat genie and she used her old box for 5 days. After 5 days I couldn't take the filth, so I threw the old box away and locked her in the laundry room with cat genie over night. She meowed all night, but in the morning I saw she used her genie, and we haven't worried since. I can honestly say our cat is happier and friendlier since she's had the cat genie!! The cat genie is loud, but that's really it---I will take that over dealing with a cat box any day...also I bought a $16 dust buster at Walmart to keep in the laundry room to sweep up the scattered granules (yes we have a hood, and they still scatter) STILL much better to spend a few seconds with the dust buster that clean that old box!! My cat used the cat genie for about a week before adding the dome, I wasn't sure when the best time to add it would be? Also, we have not had any bad smells from the cat genie. Overall, this product is amazing, and I'm so happy with it!
