Rated for 22 pounds per tier this 21 by 17 by 22.5 inch rattan cat litter box enclosure pairs a lower 20.5 by 16.5 by 15 inch washroom with a padded upper perch. Pe rattan panels reinforced by a galvanized metal frame keep the unit lightweight at 12.5 pounds yet sturdy enough for daily use. A lockable flip-down front opens for cleaning a removable cushion lifts out for washing and an included litter mat with collection layer catches scattered litter.
