I know on the internet everyone has a different opinion so I was hoping the knowledgeable members of RatForum might have a little insight on this. I know that the orange peels have D-limonene which can cause cancer in male rats and it isn't good for females either but I read somewhere in my uber research that the fleshy part of the oranges can actually reduce the chances of a female rat developing mammary tumors. Of course I found that tidbit on my phone and now that I'm trying to find the article again on the computer it seems to have disappeared into cyberspace so I can't site where I found my information. But has anyone else heard of this or actually used this risk reduction method with their girls? I bought a box of clementines last week and Mamma was trying to steal a section from me last night but I wouldn't let her because I wasn't sure of the risk. If there could be health benefits for the girls though, I'd love to share the sweet orangey goodness with them.
