Loving rats since 2002.
I was linked to this article, which is pretty good and it states that aspen bedding has some ill effect on rats, not as bad as pine and cedar but not good either. When I used aspen a while back, it really bothered my allergies and my breathing, I often wondered it if affected the rats as in a similar way.
"rats kept on aspen had greater sneezing rates and lung pathology than those on paper bedding, but also had higher body weights."
