This is Ferrets NorthWest FNW in Seattle reporting on the temperature today. My outdoor thermometer is now registering exactly 100 degrees Fahrenheit. My ferretarium thermometer is registering exactly 80 degrees F., and thereby a 20 degree F. differential exists between the outside my house and inside my house (daylight basement) in the ferretarium. All windows and drapes on the west and south sides of the house are closed. The furnace blower motor is running and forcing air through the heat registers that duct air into the house and down into the daylight basement and also into the ferret reception room. No heat is being generated, since the gas flames have been turned off in the furnace and the gas fueled fireplace insert. However the blower motor is running and is pulling air through the plenum chamber at the base of the furnace wherein I've placed a shallow plastic tray and have it one-half covered with a 1-ft by 2-ft blue cotton surgical towel, the remaining half lying on the concrete floor. To this shallow plastic tray I've added 102 ice cubes (the total output of my Whirlpool refrigerator freezer compartment) and over these ice cubes I've poured one gallon of cold water such that the shallow plastic tray inside my furnace looks like a tiny version of the antartic with ice floating in the water. The use of the blue cotton surgical towel half in and half out of the water is very useful in that it dramatically increases the surface area of the ice water and thereby increases the iced water vapor that is blown thoughout the house and into the ferretarium. I call this the ferretarium cooling system, or in German: Der Frettchentarium erfrischende Anordnung. I offer this information so that those of you who are similarly situated may put this very inexpensive cooling system into place for the benefit of your Frettchen.
