My cats love it!  The younger one took to it right away and  likes to be in the top "bucket."  The older sticks pretty  much to the lower ones. Both use the scratching post which is good for me.  I had some difficulty putting the top bucket on as hard for me to keep it centered and still while trying to screw in the 3 screws that were already  started in the bucket.  I ended up putting extra nails in it to keep it secure.  Nice looking too.
