Check out Martin's cages:

I just purchased the R695 for my 2 girls and absolutely love it. It's a mansion! You can only purchase them via their website. All of their rat cages are made specifically for rats (not ferrets, hamsters, etc.). They do however make cages for other types of critters. The sides are 1"x1/2" and the flooring is 1/2"x1/2" inch. Most ratteries swear by these cages. Be sure to spend the extra for powder coating.
