A cylinder tunnel sits in the middle of this 48-in cat tree, with a ball hanging at one end so a kitten can bolt through, swat, and duck back out of sight. Above the tunnel a thickly padded top perch looks over the room, and a large condo below stays dark for daytime sleeping. Two large platforms and one small one break the climb into steps a young cat can manage. Jute rope wraps the posts for clawing, plush fabric covers the whole structure, and an anti-toppling device fixes the 18 by 16-in frame to the wall.
