This litter box works great! I have 6 cats so it gets a workout. It is very well made and helps control the odor. Noise level is a little loud but not unbearable. I like that it tells me when a cat has used it and the approximate weight of each cat. I also love that if it senses a cat or a human during its cleaning cycle it automatically stops until it is clear. Litter draw is easy to access and clean. It's big enough that my 15 pound cat can fit into it.
