I have been extremely happy with my PetSafe ScoopFree Smart Self-Cleaning Littler Box that I got for our cats. If you hate cleaning the litter box then this is the product for you. It's so easy to set up and it self cleans. It's extremely convenient and time saving. The cats had no problems switching to this system. The other very cool feature about this product is that it connects to your smart phone and gives you tons of really cool information about your cat's bathroom health. I highly recommend this product to anyone with cats. It's a fantastic product that saves money and time.
