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. There is no set recipie for duck soup, each batch is made up for the individual ferrets preferences. Mix the solution well and puree in a blender. If the ferret does not like the taste, try different amounts of the ingredients, or feed with a feeding syringe.
