Woven cattail fluff replaces the usual carpeted box for the condo, and it does two things: it breathes in summer heat and it looks like a basket rather than pet equipment in a living room. A 16 in top perch, a 15 in hanging basket, a jumping platform, a climbing ladder and two beds spread across 50 in of height on a 28 x 20 in base - enough separate spots for two or three cats to settle at once. Solid plywood carries 33 lbs per layer, sisal takes the scratching, and the finished tree weighs 44 lbs.
