My cat Roslyn loves this cat tree. Very easy to assemble and she decided to go inside the condo before I was finished. She sleeps on the upper platform with the padding every day. She occasionally uses the hammock and other levels. I chose to install her favourite mouse toy (the first toy she received when I adopted her) rather than the fur ball and she plays with it frequently. I used treats and catnip to convince her to use all of the features of this cat tree. Highly recommended purchase.
