I am hyper-sensitive to smells of any kind, and I work full-time and go to school online full-time. Even if I had time to maintain a cat box, it's such a disgusting chore! I bought a motion-activated self-raking box for about $250, but then I had to buy another one when the first one quit working. I was getting ready to buy a THIRD box because the second one was so caked with filth and smelled so bad that I couldn't stand it anymore. But I am so glad I found the Cat Genie for around the same price! I've had it for a year and a half and it has completely changed my life. When anyone comes to my house they don't even know I have a cat right away. There is never the faintest hint of cat box odor--ever! And it stays squeeky-clean by itself. I have it programmed on a sleep schedule, so the solution lasts an amazingly long time. And anytime that I've ever needed help (like when my cat ate a rubber toy and it clogged the Genie), I have had the most amazingly knowledgeable and infinitely patient Customer Care Reps who have walked me through anything I couldn't figure out on my own (the instructions are marvelous and include pictures). I truly don't know what I would do without this miraculous innovation!
