Keeping a ferret’s coat shiny and smooth is relatively simple since ferrets naturally have an oily coat. The key is to not over cleanse your ferret – that could lead to dryness, itching and a dull coat. Realistically, ferrets only need shampooing once a month. Over-bathing strips the coat of essential oils and can actually cause a ferret’s musky odor to increase! Brushing your ferret’s coat is important, not only because it makes the coat brilliant and glossy, but it also aids in the prevention of hairballs by removing loose fur. This is especially important during shedding season. Ferrets do not cough up hairballs like cats and they are prone to getting hairballs; so always keep some Lax or petrolatum on hand to help those hairballs move through their system smoothly.
