Please don't let your ferret suffer or die because you were not prepared to take on the responsibility of pet ownership. If you can't afford high medical bills, don't own a ferret or any other animal. Pet ownership does not come with a good health guarantee . Pet ownership does come with the responsibility of caring for another life. Make an appointment, or take your ferret to a vet before you wait for an e-mail about your sick ferret.
Ferrets can become critically ill very quickly due to their small size and fast metabolism.
