This is a nice cat tree and with a little catnip encouragement my 2 cats took to it.  I only gave it a 4 as the tall part does wobble a little even though the screws are as tight as can be.  Also, the bottom long sisal post that is suppose to roll while they scratch it is made too tight and doesn't roll.  I think if it did roll the cats would have enjoyed it as a both a toy and useful scratching post. Otherwise they love the middle perch, the hanging toys and the round top area. Well worth it and a nice size.
