Can not believe I waited so long to make this purchase!! If the price tag scares you then just think about how much time you spend cleaning and washing litter boxes!! This is the greatest invention since bread and a great investment!! I never enjoyed pooper scooping and having to throw out the cat litter every so often and wash the litter box! And I definitely never liked the smell of the litter box. The cat genie has eliminated that daily and weekly grind. Now you must take the CatGenie apart every so often and clean it! Even IF you use the maintenance cartridges which I do. You still MUST clean the CatGenie by hand every so often. I did not know this until I spoke with someone at Catgenie. It doesn't take long to take it apart and clean it and put it back together. And I had much rather do this once every 3-4 months than deal with regular nasty cat litter on a daily basis. My cats track the granules all over the house a few at a time. I have not found a way to stop this but I prefer sweeping up some granules to dealing with a regular nasty litter box. The CatGenie was easy to put together. And my cats took to it right away. CatGenie has recommendations for cats to get used to using the CatGenie. Customer Service is excellent and very helpful should you ever have a problem. And there's no waiting on the phone because you leave your information and they call you back pretty quickly. I highly recommend the CatGenie and sing it's praises! I've had my CatGenie for just over a year now. It has spoiled me!! Do make sure that you have enough cartridges and Washable Granules on hand so that you do not run out! I've ran out of both before and had to rush to the website and spend a small fortune on overnight or 2nd day shipping. Totally my fault of course. I encourage the VIC subscription so hopefully you do not run out of either. Now that I have the CatGenie; I can not imagine ever being without one again!!
