Six levels over 64 in gives a climbing route rather than a stack of shelves, and the spacing lets a cat move up in short hops instead of one long leap. The top perch measures 20 x 16 x 4.5 in with soft padding for the highest sleeping spot in the room. Below, a 19 x 19 x 14.5 in condo with an 8 in entry hole offers an enclosed retreat. Thickened boards and solid support posts stand on a 23 x 23 in base, and the tower weighs 45.5 lbs - the mass that stops a running cat shifting it. Engineered wood with fabric and PP cotton padding.
