I found a few articles, but unfortunately not very much. It's odd how few rabbit care articles on the web are actually informative.
Anyway, I saw the discussion on this thread shift from "caged vs. non-caged" to "wire vs. solid floor" and since I didn't know which you wanted, I included a little of both. Threw in some "indoor vs. outdoor" as well in case you wanted to add that to the paper.
Quick note to any RTers who see these articles: I'm not taking sides in any of the mentioned debates. As long as a person's rabbit is healthy and happy, I don't care whether they're in outdoor hutches or sleeping at the end of their owner's bed. I'm sharing these links solely for the purpose of helping bunnychild with her research.
