Paula I'm so very sorry to hear of your loss. The first question that came into my head when I read this was....do you have natural gas heating? If so it could be carbon monoxide poisoning? Carbon Monoxide is both tasteless and odorless. It often goes unnoticed until it is fatal. People will often complain about dizziness/headaches in the morning without even realizing that this poison is leaking into their homes. Small animals like ferrets/hamsters/birds etc would succumb to it first. If you are unable to determine the cause of your babies deaths please have someone out to check your furnace. I've also posted this to the list as it is something everyone should be aware of if they heat with natural gas. Barb Gustafson Alberta Ferret Society President [Posted in FML issue 2897]
