For me I like things that are overkill. Being a Professional Engineer  I don't like anything that is not rock solid. This unit is good enough  for most and it will withstand cat activity reasonably well  but it could be stronger.  I doubt it could stand up to a 40 pound Savannah  breed cat.


Pros: Goes together easily and  with minimal need to look at the instructions
Cons: Could be "beefier."
