We'd have to find space for another 2 litter boxes in the house. We have 2 LARGE litter boxes as is ....
I hear you on that one, Masaki. That was always an issue for us, too, when we had multiple cats. There just aren't a lot of places in a house to put such an item.
It sounds like you have thought of and tried everything and that Shadow is just a sprayer.
