The simplest way to bathe a ferret is in the sink. Fast and easy. Or you can put a couple inches of water in the sink or tub. Never leave your ferret in the tub with the water running or unsupervised. Ferrets cannot swim well and can quickly drown if the water is too deep or left unsupervised.
Some ferrets also like to take showers and baths with their owners.
After their bath, dry as well as you can while they're squirming then place a couple towels on the floor, couch, or chair and let them finish the drying process. After baths, ferrets are extremely frisky and you're sure to enjoy their post-bath antics. Too frequent bathing causes the ferret to replenish skin oil and will result in a musky smelling ferret. Bathing a few times a year, unless they get into something, works well. B. Ears - Ferret's ears get dirty easily.
