We rescued a 4-week old kitten (found in a trash dumpster!) and while we were happy to adopt a cat after being without one for a few years, the idea of the litter, the litter pans, the odor, the litter all over the house (in the joints of hardwood floors!)... it was just not a happy idea. Found the CatGenie online, and ordered it immediately. First of all, it's high-quality. Installed easily. Works perfectly. At first, we thought it was a bit noisy, but after a few days, I guess WE became acclimated to it, and now we never hear it at all. The only issue we had was acclimating our kitten to the CatGenie... he was using a normal litter pan without a problem, but wouldn't go near the CatGenie. We left it alone for a week or so, then followed the advice of another user and used the original litter pan and litter and gradually incorporated more and more of the CatGenie granules into the existing litter (25% CatGenie granules, then 50%, then 75%...). It meant discarding the CatGenie granules used in that process, but it WORKED, and the kitten got used to the new granules. We also moved the existing litter pan closer and closer to the CatGenie in the laundry room over the period of a week or so, and that did the trick. After about 10 days the kitten was using the CatGenie exclusively, and out went the old litter pan. And litter. Another thing we love... the granules do NOT track all over the house. A VERY few will be on the floor outside the CatGenie, but VERY few, and we almost never see the granules anywhere more than a foot or so from the CatGenie. The kitten is now almost 3 months old, and life with him, and the CatGenie, is glorious. We would recommend this product to anyone and everyone! Oh, the dome is also terrific... makes this look less like a litter box than it is! Bravo, CatGenie! Bravo!
