I was very excited about this cat tree, but unfortunately it is a disappointment. First of all, it really would only be suitable for very small cats or kittens. The platforms are very narrow, the base is narrow, and the ladders take up all the room my cats need to comfortably move from level to level. The base being so narrow, combined with the height of the tree, makes it very wobbly too. We had to add another board at the bottom to give it stability or it would have toppled with the first attempt to climb it. Finally, the little houses on it are very tight, and even my average size cats (9 and 12 lbs) can't fit inside comfortably. They are very sad that their old tree is gone in favor of this one. Despite the expense, I'm going to have to go out and get a new tree that they like more. Very disappointing.
