Consider wearing a scarf around your neck to protect the collar, which can be quickly matted. Avoid insecticides, mothproofing and other chemicals around on your fur, including perfume or hairspray directly on your fur. Perfume contains alcohol, which can dry your pelts. Oils in the leather of your fur can become rancid and smell. If your fur gets wet, don't panic.
Most furs handle snow and a light rain with ease.
Shake it out and hang it to dry in a well-ventilated room, at home or office. Resist the temptation to speed the drying process by using a hair dryer or hanging it near a heat source. Fur does not like heat. After it dries, shake it again. Do not comb or brush it.
