amelia, for the RUUD, lay out all the pieces, it will make sense if you lay them all out together. I have put together an R-670, and R-660, 4 R-680's, an R-695 and the RUUD. Go slow, lay it all out so you understand how it works and if you can get someone to help you, thats even betterameliaflame said:Martin's does make excellent cages at an excellent price, and mine came within 4 or 5 days, but a warning: The larger cages come in pieces with (at least for me) complicated, short instructions. I still have not been able to get mine togethor for fear of putting it togethor wrong and having wasted $150. Plus it requires extra tools to put it togethor which I do not have so it is a huge hastle. If you are handy with things like this though you should love your cage!
