Ferrets have a natural musky scent, and occasional bathing with a gentle, ferret-safe shampoo cleans the coat and can help manage odour, though over-bathing actually increases scent. The best shampoos are gentle, ferret-appropriate and kind to skin. We compared ferret grooming shampoos on gentleness, deodorising and safe ingredients, so you can clean your ferret without drying its skin or worsening the smell.
