As soon as we assembled our cat tree, the guys were all over it. They love it. I wish the platforms at the top were a tiny bit bigger as we have twelve pound cats. They play and nap on it all the time. The hammock/swing is too small for them, but kittens would love it. The pom pom swat toys were destroyed the within the first few days, but we've attached others. We're very happy with the cat tree and were pleased to see the stiff rope uprights for scraching.
