My cats absolutely love this tree. There's rarely a moment that there's not a cat on it.  I woke up in the middle of the night the first night it was up and noticed the 2 who pin my feet at night were missing.  I found them on the tree. 

The only con is the instructions could be a bit better. After assembling my aunt's with a friend it was easier to assemble mine. 

Make sure the poles you use on the bottom do not have the holes for the hammocks.  To put in the hammocks in, insert one end in a pole that is in place with the hole toward the center.  Keep the other pole turned a bit then turn it into place with the screw on the other end of the hammock inserted. I hope that makes sense.  But do the hammocks as you go or you have to disassemble to place them.
