Any other over the counter remedies, please check with your veterinarian first. Poisons Many plants are toxic to ferrets, so are rat poisons, human medications, antifreeze, and some bug sprays. If you suspect your ferret has been posioned, get him to a vet immediately. There are two animal poison control numbers, they are not free, but they may help save your ferrets life. Blockages Ferrets love to chew on just about anything, and as a result, can develop lifethreatening blockages very quickly.
Hairballs can also cause blockages, that if left untreated, can be fatal.
Symptoms of a blockage include pawing at the mouth, vomiting, intemittent appetitie, black tarry stools that come and go, and just generallly wasting away. Prevention is giving Laxatone, Petromalt, or just straight Vaseline once a week. Treatment is usually immediate surgery to remove the object. Duck Soup Duck soup was named after the ferret it was originally invented for, to help keep the ferret eating. Occasionally, if you have a sick or recovering ferret, they will not be interested in regular food.
