We are preparing to adopt two guinea pigs from a local rescue. (Thanks to this website for the cage idea and information -- we never would have a chosen such a large and suitable home without it!) I purchased a large bag of kiln-dried pine bedding, and have been airing it out before using it...we had planned to cover it with a light layer of carefresh as well to help with any remaining phenols. But the more I read, the more concerned I am about whether it is a good choice. Does anyone out there use pine, and are you happy with it as a bedding in general? How long to you air it out before using it? I'm just trying to muddle my way through this, so ANY help would be appreciated!!!
