I cant say enough on how easy this was to put together. No rocket scientist required.  The cats were a little hesitant then the youngest jump on the box and began paying with the balls. Next everyone wanted part of the action. The only negative I have is I will the dangling fur ball was attached by Velcro.  The baby leaped, grabbed, and tore the thing down within a day.  I attempted to tie it together but no good results came of that.  Other than having a destructive kitten there is nothing better for the price than this tree.  

Pros: great value, easy assembly, nice to look at
Cons: dangling fur toy tears off easily
