A 58-in cat tower built vertically on a 22-in by 18-in base, so it fits a corner in a small apartment while still giving a cat plenty to do. The padded top perch measures 14-in square and holds a full-grown cat stretched out for sunbathing. Below it a roomy 11.5-in condo offers a dark place to sleep, and climbing platforms step up between them. Three hanging balls swing at paw level for solo play. Natural sisal posts absorb the scratching that would otherwise land on furniture, and an anti-tipping device secures the 29-lb frame to the wall.
