Great cat tree!  It's first come, first serve on who gets to sleep in the top crow's nest with my two they both love it. My cats weigh 9 lbs and 11 lbs. 2nd favorite place is hanging out in the top house!  They do like to play with the vines, so don't think they will last long though.  Have the brown/green one, looks good! Beware, very large so you need a place with room!
