I really like this PetSafe ScoopFree Automatic Self-Cleaning Cat Litter Box but it’s more costly in the long run than a traditional litter box. It’s really easy to use and more importantly, it's easy to clean because you don’t have to do much work, it does it for you. Though, it is not perfect, I still need to scoop it out periodically. It is more expensive because you have to purchase the disposable litter trays and the crystals are a bit pricey. But I think it’s worth it in the long run because it’s much less work for me. I recommend giving it a try.
