Yup, I'm back. Just a quick note. About redwood chips that someone mentioned a while back. Just like cedar, long term exposure to redwood dust can cause respiratory problems as well as throat or nasal cancer. Rather like smoking ... This is well established with humans in the woodworking/lumber (particularly planer mills etc) industry, and is listed in NIOSH (National Institute of Occupational Safety and Health (or something like that)) advisories and regulations. I don't recommend using cedar or redwood for bedding. Other known toxic domestic woods are juniper (aromatic cedar), oleander and mimosa. The woods that are rot resistant tend to be rot resistant because they produce compounds that are toxic to organisms that cause wood to rot. Hence it should be no surprise that sometimes these compounds are toxic to things other than wood rot organisms. Like people. Or ferrets. [Posted in FML issue 0946]
