Hello everyone, Does anyone know whether or not the powdered form of boric acid is harmful to ferrets (it's the kind that you can buy a big thing of at Walgreens)? I have been researching it and some places say it's ok and others say it's a don't. I don't want to put it on the ferrets directly, I just want to put it in the corners and cracks to keep out bugs. Thank you for your help. Sincerely, Kayla, Harley, Ihop, and the angeled Vienna [Posted in FML issue 4924]
