We have had our CatGenie for 2 years. I just received the GenieDome & absolutely love it! We have 2 cats & they don't seem at all bothered by the new addition to their 'potty'! The Dome & sidewalls went together with ease & was super simple to attach to the Genie. I only wish I had seen the new door to complete whole thing! Oh well! My oversite but it will definitely be my next purchase! I highly. highly recommend this product to help save on granules & to give your purrbabies bathroom privacy!
