Tim,
In the popular Ferret Hard Cover, " A Practical Guide to Ferret
Care"(Jeans,1994), It states that ANY wood derivative can cause
potential respiratory problems.  Your not alone though, I have even seen
many Pet Shops, use wood chip bedding products- which goes to show how
grey and miscommunicated of an area it is.
Enjoy.
