This literally box is huge! It’s a good design and the WiFi enabled part is pretty neat. We only have one cat so it’s nice to not have to empty the box very often. We haven’t had it long enough for her to really be used to it but she’s gotten in it and sniffed it so far and doesn’t seem to be scared. The cords a little short so that’s the only thing it has to be close to a plug which is hard in an unfinished basement.
