I have three cats and found the time, effort, and money spent on maintaining two litter boxes (and about 80lbs of litter a month) was just too much. I finally decided to splurge on the catgenie and am so glad I did. I had wanted one for years bit had never had a bathroom/laundry room that would fit the catgenie (it would be nice if the overall size of catgenie could be reduced without sacrificing actual litterbowl space). Anyway the catgenie was simple enough to set up and my cats have been adjusting to the catgenie fine (we're on day 5 of transitioning and i have officially thrown out the other litter boxes and the first stools were found in the catgenie this morning). This is well worth the money to not have to buy cat litter twice a month and scoop stinky litterboxes. I'll also end up saving money in the long run in not having to buy so much litter and the granules and sanisoution cost less than litter. I have not started using the genie dome yet but will try it out once the cats have fully transitioned and aren't as wary of the catgenie.
