Cold and flu viruses thrive in warm, dry environments. These are precisely the conditions we find ourselves in during the winter when the cold reduces the amount of moisture that the air can carry, and our heating systems further dry out the air in our houses. Humans, ferrets, and other pets can benefit from having a humidifier running, at least during the night. A humidifer could help reduce susceptibility to colds, and also make us and our pets more comfortable. Unfortunately, humidifiers may also spread certain bacteria and fungi that like moist environments. Be sure to change the water and wipe out the reservoir daily. Your ferret does better with colder temperatures. As long as your pet is healthy and has a full coat, keep her in a colder room if you need the heat cranked up for your own comfort. -- Lee, one of the Massachusetts Ferret Friends -- Lee [log in to unmask] [Posted in FML issue 1821]
