I ordered this for my 7-pound cat to give her an elevated place in our apartment. She is much smaller than the average cat, but even she could not fit into the tunnel. The tower is very cute, and the material covering the surfaces the cat will touch is very soft. However, the base did arrive broken, and the instructions were not entirely clear when assembling the cat house, so it is not facing forward. This works for our cat, which prefers her privacy but this could frustrate someone who wants to see her cat. Overall, this is an effective cat tower for the cat that we have.
