We absolutely love our CatGenie! Dexter took to it immediately and it was safe enough for him even after having his front claws removed! While the initial investment is costly, the ease of use and convenience is completely worth every penny. The only problem we've had so far was the dryer overheating, and CatGenie sent us a new processing unit immediately and with the best customer service I've received in a long time. Dexter occasionally rebels and leaves us surprises around the house, but it has nothing to do with his awesome litter box. He ony does that when his routine is altered or we're gone for an extended amount of time. He just likes to cause a little drama every now and then to prove he's boss. :) Overall, the CatGenie is one of the best investments we've made and has made our daily lives so much easier!!! Thanks!
