My two cats instantly took to this high quality cat tree, ok a little cat nip didn't hurt either.  I love how many scratch posts this tree has.  It is quite sturdy as they run up and down and jump off of it and no tip overs!  The ivory color looks great in our living room.  It took my husband approx. 1 hour to assemble it.  I would highly recommend Armarkat brand to anyone looking for a high quality cat post/tree.
