Really neat contraption, great way to monitor litter box habits. If you have multiple cats you can individually monitor by weight. Only one of my cats will use it, as my chonky cat (shown in last pic) is too chonky to move around inside it. But if your cat is under 20lb they should be good. Inside the trash compartment on the bottom there’s a charcoal type filter that helps with absorbing odors which I love! I did get a notification on the app to replace it every 15 days, which seems way too frequent. Can’t even purchase the filters yet from what I can tell. I’m curious to see how it holds up long term, I have a feeling it’ll get kinda nasty on the inside but haven’t had it long enough to tell how easy it’ll be to clean. Hope that some accessories will be released for it, like stairs!
