For the most part it is a good solid cage … The pieces did not line up once put together leaving a gap on one side at the bottom, also one of the screw threads did not fit with the screws itcame with which was a pain. Even though the water bottle that came with it has a rat on it, the cage is most definitely not meant for rats. The spaces are too far apart. Luckily our girl gets enough attention she doesn’t try to escape from it … but totally could if she wanted it to …
