A 17.5 x 14 in top perch on a tower only 26 in tall gives the surface area of a much larger tree at a height an older or arthritic cat can still reach. Two condos share the base, each 12 x 11 in, which suits two cats or one cat that likes a choice. Each tier holds 29 lbs. Soft fiberfill under skin-friendly fabric lines the perch. The footprint is 16 x 13.5 in and the whole piece weighs 11 lbs, light enough to move between rooms. Sisal posts handle scratching; assembly is required.
