I bought this for a second home for my critters while visiting my parents in another state,so they would have ample room and not be uncomfortable in a small cramped travel cage. I have not tried it out but did pay a  short visit long enough to put it together and get it ready. The box indicates " no tools needed" okay that is a joke!!! you need tools especially a hammer to bang the peices together that do not fit and were not propery saudered.No way could I have done this without the help of some brute muscle power from my dad,it actually took three of us working together to put the cage together.It does look really nice and hope it serves it's purpose, I really won't know if there are any quirks until I go for an extended stay with my animals, I bought the cage for my 2 prairie dogs and resued squirrel. This looks like a very safe cage for the prairie dogs,which is hard to find for them.
