this is a wonderful tree for our furr babies.  our two kittens are not sure about the hole in the middle of the first level. but then they have never had this either. they will get used to it. the carpeting is extremely soft. i love the different colors. it is visually appealing. our kitties love the condo and the rope. they are starting to check out the basket. i was worried they would not get to the next level. oh yea of little faith. LOL they will find their way. they have been checking it out. one of our kitties is all about heights, so it wont be too long before she is on top.  this is a fun tower for both kitties and humans. do want to make sure it is attached to the wall. it is a little top heavy and can be tipped if the kitties start running at full speed going up. the instructions on doing this are simple.
