My 2 cats really love this cat tower.  They love jumping from level to level, scratching and stretching on the 10 scratching posts, chilling in the condo with side view window and hanging out up high overseeing everything.  The tower is very well made. It took me about 20 minutes to build with the allen wrench and fasteners provided.  Instructions are merely photos... a little text would have been helpful.  I've had other cat towers but this is our favorite!
