Due to a medical condition, we keep our house at about 64 during the winter and 68 in the summer (with non-stop complaining from Larry). We keep a small heater in the room with the ferrets and they actually only deal with the cooler temperatures when they are out running around. We've not seen any problems with the ferrets from this, but Larry is convinced it will be a problem. Any thoughts? Debbie Whorley [Posted in FML issue 5159]
