Self-Cleaning Cat Litter Box - Large Capacity Automatic Litter Box for Multiple Cats | Open-Top Design with Safety Protection | Ideal for Home, Office & Multi-Cat Households

My cats have had the Furoomate for about a month now. One is a spunky 2 year old male tux and one is an ailing, aging grumpy female calico. The calico has been having bathroom issues for about a year, refusing to use a litter box for pooping. I have her using puppy pads at the moment- manageable but not ideal. She will still use one for urine, but it must be pristine. I have three boxes throughout the house.Anyway I bought the Furoomate hoping it might change something for us. The price point was nice and it seemed less complicated than other automatic litter boxes. Nothing to assemble, just unbox, plug in, fill and start using. When it arrived I did feel the opening was high enough I’d want a step - especially if the elder cat had any chance at liking it.My young guy checked it out for a few days before getting in. He was extra cautious, and despite the fact that it seems very small for him he was doing well with it. Until a few days later he caught it cycling for the first time. That freaked him out, and had escaped his attention because it is SO QUIET!! He stuck his head in the hole while it was turning and it stopped, which made me feel good about safety. It took a few more days for him to use it again though! He now uses it pretty much exclusively.My older cat shows no interest in using the furoomate at all. It is entirely too tall, narrow/small, with a small opening for her. That’s okay. It keeps the boy out of her box which makes her less grumpy and makes cleaning hers easier.Emptying it is easy and clean, I don’t notice a smell.My observations after a month:Good value for the price -but factor in the cost of a “step”.Very quiet operation. I’m very sensitive to noise and live alone in a small space and never hear it. I’ve walked in on it mid cycle and been surprised.Easy to operate.Easy to clean.Seems sturdy.Very small interior litter space. Especially for the size of the entire unit. Even a couple inches wider would make a difference. This is my only complaint, I’m just lucky one of my cats doesn’t mind.In the future an add on dome or lid might be nice.Overall I’m happy with the purchase.
