In the late 1990s a doc student ferret owner did a review of the literature regarding cedar and pine toxicity. His name is Jeff Johnston and we were both members of the Triangle Ferret Lovers Club (TriFL). You can find this paper at http://trifl.org/cedar.shtml thanks to his generosity and the maintenance of webmaster extroidinaire, Pam Sessoms. If, for some strange reason this does not open for you, let me know and I will email you a copy of the paper. -- renee :) It's amazing how much can be accomplished if nobody cares who gets the credit!
