This 58-in modern cat tower stacks two condos, a woven cat basket, a hammock and an upholstered top perch onto a 24-in by 18.5-in base. Both condos open through a wide entrance, so a larger cat does not have to squeeze through a narrow hole to reach the bed inside. Broad jumping platforms bridge the levels for climbing practice, and scratching posts sit along the route up. Hanging balls dangle for a swat in passing. Thickened wooden boards and sturdy posts carry the 40-lb frame, and the wide base holds it steady in a corner.
