My husband and I are moving to the Seattle area. We have a lease on an apartment and my husband tells me that it has base board heating. I have not seen this yet, and am not familiar with this. He has said though, that it will be a problem when the ferrets are out to play. There is one unit that has holes at the end that the ferrets could get into. Does anyone have suggestions on how to ferret proof these types of heating units? Thankfully I have a few months to work on it. Any suggestions would be appreciated. BK [Posted in FML issue 3832]
