If you adopt a ferret, be a responsible pet owner, and be prepared to care for it. Ferrets do require some special care. Dogs are easily taken to a groomer, and there are some pet groomers that will take ferrets as clients, but this can get expensive. Instead, you can provide general care for your ferret.
Never bath a ferret too often. They have natural oils that keep their skin healthy, and over-bathing them can dry out their skin and cause irritations. Some people bath their ferrets once a week. This is fine, but really still too much. Ideally, your ferret will need to be bathed about once or twice a month. You should use baby shampoo that will not irritate his eyes. Also note that ferrets groom themselves just like cats do.
