I've had this cat tree for about a month. I have an older, large indoor cat (she's 10 years old) and she does use it every now and then. She definitely likes to scratch on it and enjoys (and fits!) into the cubby hole  on the tree...really no complaints. I bought this as a way to protect furniture (which is seems to do) and to give my indoor cat a way to play and let off some energy, look outdoors through the window, etc. All were successful in varying ways.
