Two doorways into the 11.5 x 11.5 x 10 in condo mean a cat can slip through and out the other side rather than being cornered - a detail that matters in a household with more than one animal. Above it, a 14-in square top perch is edged in plush for napping in a sunny window, and a fabric hammock slings between the posts below. Sisal-wrapped posts run between the platforms for claws. The tower stands 44 in on an 18 x 13.5 in base and weighs 20 lbs, with engineered wood boards under the gray fabric. Assembly is required.
