A friend recommended this to us and it has been amazing!!!! This system beats scooping litter and dealing with the smell and mess of litter! It took no time for my cat to jump right into the genie and has not had any issues with using it. The only downside are the little granules get stuck in her paws and they get tracked around the house, but I'm sure litter did the same I just couldn't see it as easily. You will not regret buying this!
