I am getting a cage for 2 rats, and do the floors have to be solid(like this http://www.petmountain.com/product/s...w-x-30-h-.html), or can they be mesh(like this http://www.martinscages.com/images/full/r-680.jpg)

would the rats foot get caught in the mesh? I would prefer to get a mesh one because the waste would fall into the bottom for easier cleaning, and in the solid cage the waste would just sit around and make it much more difficult to clean.

do any of you have a rat cage with mesh?

hope you can help
