That tall one from Wal-Mart has a pole to the ceiling like an old Johnnie Pole...I have ben thinking of getting it as well, but it has no little houses that mine like to sleep in...it might be good as a frame though and build off it...
What I really need to do is get off my lazy arse and build the perfect one from scratch...that is the only way you can rally get one that suite your cats needs.
