I have had the cat tower for almost two months and my kittens love it.  I have two boy kittens that are about 4 months old now.  They love to run up and down the tower chasing each other. My favorite is when they play in the house attacking each others tale.  I have a small one bedroom apartment and this fits in a corner of the room without taking up to much space.  It is tall though and if you are shorter than 5'8" then you will not reach your cat on the top shelf.  Some of the reviews said it wobbles, which is true but it is not going anywhere. The only way any cat tower won't wobble is if you screw it to the ground.  The only downside is that I can't find a toy to attach that the two boys won't chew off.
