My 2 year old cat hasn't liked traditional scratching posts in the past, but she loves these posts.  We've had the tree set up for almost a month now and I thought maybe she would use it less as time went on, but she's on it multiple times a day whether napping, watching the dog, grooming herself on the rope, using the posts, or going crazy with the toys.  The only thing she doesn't like is the hammock--I tried to put her in it once and she freaked out.  Only took about 45 min to set up, and that was with having to undo two pieces because I didn't look at the directions before I screwed them on.  :)   Looked all over the web for months and this was the best deal, totally happy with it!
