Four activity levels on this mushroom cat tree give indoor cats places to hide, scratch, and perch in one vertical structure. A mushroom-shaped condo and a large trunk-shaped condo offer enclosed retreats so cats can rest or overlook the room, while the 14 x 20 in cat condo size and 19 x 12 in top condo interior support lounging. Thick 8-in scratching posts wrapped in sisal carpet provide a durable surface for clawing, and each tier supports up to 33 lbs. A wide base helps reduce wobbling, and the polyester peach skin covering feels soft for daily use.
