Reaching 71 inches over a 34 by 16 inch base, this tower stacks two 13.5 by 13.5 by 14 inch condos, a 12 inch top perch and a side bed so three cats can each claim a level without crowding one another. Condo entrances measure 7.5 inches square, wide enough for a large adult yet snug enough to keep the interior dark. Four fully wrapped scratching posts run between the platforms and a two-in-one sisal board doubles as a climbing ladder, giving older or heavier cats a graded route to the top instead of a series of jumps. Each layer supports up to 33 lbs. Engineered board panels covered in polyester fabric give the tower a finished look that works as room decor, and its 37.5 lb weight with a wide stance holds it steady when a cat launches from the highest perch. Assembly is required, and the side bed sits low for a cat that avoids the top perch. The condo entrances measure 7.5 inches square for an adult cat.
