Yeah, I remember hearing “one more box than you have cats”.
Man. I’d have to quit my job just to do litter box maintenance if I had 6 litterboxes.
My five share two boxes. Scoop twice a day, total change of litter twice a week (give or take), wash the litterboxes with some very hot water and Pine Sol once a week. I feed them the expensive cat food that’s low in magnesium, which actually does help their poop smell less… poopy. And keeping the scoopable litter fresh avoids the ammonia pee smell.
I’d consider buying one Littermaid, but I know my neurotic freaks would never ever use it. Good God, it makes noise! I can see their horrified little faces now. Heehee!
