New England housing has a variety of heating methods. Forced hot water is usually found in baseboard units or radiators in homes. Ferrets can be very good at prying the covers off baseboard units, exposing themselves to the hot pipes. Radiators and baseboard heaters need to be isolated from your ferrets to prevent burns. Dehydration and shock can occur in severe burn situations, and pain medication will be needed in all cases.
Different dangers exist with forced hot air heaters.
Ferrets have been known to crawl into vent systems, requiring owners to search the house with squeaky toys while disassembling the ductwork. Make sure all vents are securely fastened. Heating of all types leads to dry air in the house. Humidifiers and an increase in water available to all pets will offset the dehydrating effects of dry heat. Vaseline or aloe can be used on dry noses and paws.
