This is not very sturdy. My 6 lb cat goes to the top and it wobbles. My 15 lb Maine coon makes the whole thing shake. I tightened all the screws and a day later they were all loose. Weird. The faux fur feels cheap. The ramps are still loose after being tightened as much as possible. I would have returned but it would cost too much. I wouldn't buy this brand again I'm going to keep it while it last and then buy a higher quality tree for my babies.
