A double-decker cat house sits at the heart of this 55.5-inch tower, giving two cats separate floors inside one enclosed shell instead of forcing them to share a single condo. The bucket-shaped house measures 16 inches across and 31.5 inches tall with an 8.5 by 7.5 inch doorway. Above it, a wide top perch is broad enough for a cat to stretch out flat rather than curl up. Jute-wrapped posts over a solid wood core stand up to hard scratching, and a 2-inch thickened MDF base spreads the load across a 31.5 by 19.5 inch footprint. Teddy fleece covers the platforms for grip and warmth. The tower ships in two boxes and weighs 54 lbs assembled, which is the reason it stays planted when a cat arrives at a run.
