My kitten absolutely loves this. I gave a poor review because it did not last more than 6 months. My kitten is only about 8 months old, and barely weighs anything, and the two tall tiers with the round thing that they sit on or lay in, the first lower one last about 3 months and had to be taken off because it wobbled it didn't hold my kitten on it. The the highest tier after about 6 months, same thing, became so wobbly that it is no longer usable. If my kitten attempts to jump on it, it just tips over. This is very poorly made, which is sad because my kitten loved it.
