What can i say?  My two cats can be found on it night and day.  I took care to tie the toy short enough to keep them safe, as per warnings from other customers.  Watching my cats run up this tree, scratch, reach for the toy, then settle down to nap, one on each platform, is the best feeling.  They've even stopped tearing up my rugs.  I can't say enough about how cool this tree turned out to be.
