“Not published” means the maker does not state it. One rule per row: a bigger figure wins (cat weight, days between emptying, warranty), a smaller one wins (smallest cat, floor space, height). Shape, big cats, odor, app, litter and sensors get no winner: makers and testers describe them in their own words.
