I have a painfully shy and nervous cat rescued from a shelter.  He hardly plays with any toys but he loves this car tower.  In 5 minutes of assembling (easy for my daughter to do the job), he started scratching and exploring the tower. The on,y thing is that I wish the top resting areas are a bit more stable and bigger. He jumped on them and got scared of the shake. Besides that, this is perfectly fine looking tower. The best xmas present for my cat ever!

Pros: Easy to assemble, looks good, very soft, cat loves
Cons: A bit shaky when an adult cat jumps on the top
