Right now I've got my rats in a glass aquarium, but I'm concerned that may not be appropriate for them. One has a bit of a sneezing habit, and I think a real cage would facilitate fresher air. So, I dug out my dad's old bird cage and cleaned it. Only problem is parts of it are pretty rusty. It would be a great big pain in the butt to scrub the whole thing, so I'd rather not.

Thanks in advance!
