The cat tree arrived in a timely fashion as usual. Directions were not the easiest to understand but if you take everything out of the box and mark the parts yourself it moves along. 

There is a LEFT and RIGHT square where the top portion of the upper ladder connects - be sure to look on the bottom for those extra holes.

The cats (4) love it and have been claiming their space/doing acrobatics since its gone up!

It would get a 5 star rating if it were sturdier.
