My cat loves this thing!...he started to used as soon as I was putting it together, which is REALLY simple (I love that). The material it's made off is really nice and soft, and my cat explores all the places in it. He abandoned his place in my bed to sleep in the highest place of the cat tree (and come backs in time for me to wake up). The only reason I don't give it a 5 start is that sometimes when he jumps to it, it wobbles A LITTLE.
