I absolutely love this litter box for my cat. Setup was simple and you just have to plug it in. It comes with a disposable litter pan and you will have to purchase replacements. The cartridges only last about 3 weeks, so you'll have to make sure you purchase those along with this. After about 20 minutes, the rake pushes the feces under a hidden hood and it helps with the smell! There isn't much litter debris that pops out, but it still does happen. They do sell a hood attachment and I will be purchasing this to help hide the smell even more. It is a bit on the larger size, so take that into account. Overall, I don't have to change the litter as often and it is more convenient. I would definitely recommend this to any cat owners!
