At 25.5-in tall and 24-in wide, this cat tower stays under most window sills while still carrying two condos and a 19 by 16-in upholstered perch. The perch is filled with PP cotton and wide enough for a cat to stretch flat rather than curl at the edge. Below it, two 13.5-in condos sit side by side with openings large enough that a heavier cat does not have to squeeze through. Sisal-wrapped posts run between the levels, thickened boards carry 22 lbs per layer, and an anti-tipping device secures the 18-lb frame to the wall.
