I bought this item because nothing is too good for my cat. What was I thinking ? Firstly, part of it wobbles. I've taken it apart and put it together again three times, but I can't tighten it up enough to keep it rigid. Secondly, my cat shows no interest in it whatsoever ! She ignores it and prefers to scratch the carpet. This purchase was not one of my better decisions. Update - months later. In the interest of fairness, I should say that my cat now sleeps on it (ironically on the part that wobbles) and has also started to scratch it too, so I've given it another star.
