Like every-one’s comments, I was a little hesitant to purchase due to the price. It was the best buy I could have invested in. It works great and my cat adapted right away. It is so nice not having to clean a litter box daily. One thing I would recommend is buying the gate. My cat kicked litter out the Litter Robot but once the gate was installed that was the end of that. The Litter Robot is quiet, hardly any smell and it does what it says. You only deal with the smell when changing the box. I love it and defiantly recommend this product.
