both will be a PITA to clean, the have tiny doors and while I've made sure to avoid rats I think they are smaller then ferrets and friends fuzzies have escaped from super pet cages. I'd look into a Ferret Nation- you'd just need to make some coroplast boxes for the floors then the cleaning would be a breeze and the space would be great.

whatever you decide i'd look into pricing on another site.
cage 1 - $142.49
cage 2 - $78.99
and www.ferret.com has $6.99 shipping on anything
