Duck Soup, also called Ferret Soup and similar things, is a high-calorie, high-protein concoction meant to be fed to sick or old ferrets in order to fatten them up and help them regain their health.

There are many different recipes for Duck Soup. A number of our members have asked for the recipe we use, so here it is.
It will cost about $50 to buy all the ingredients initially and many of the ingredients have a shelf life. To extend the life, after making a batch, you can pour it into an ice cube tray and freeze them. Then transfer them to a plastic bag so you can have them available when you need it. You would use 1 or 2 cubes, microwave until they are just slightly warm. Make sure you test the temperature on your wrist before giving it to your ferret.

Here is the recipe:
1 can a/d by Hill's Prescription Diet (5 oz)
1 tablet crushed papaya 65-75 mg
1 tablet crushed chromium 250 mcg (use for ferrets with insulinoma - otherwise, omit)
1 cc Karo syrup

Take these above ingredients and thoroughly mix. Let stand for about 45 min.

1 tsp. Pet Tab granules
1 tsp. Brewers yeast
1 Vitamin E 400 IU
1 cc Pet Tinic

Add the 4 ingredients above to the first mix and stir well.

10 oz. Water or chicken broth - heated but not boiling.

Add water/broth slowly until well blended. Serve warm

Refrigerated shelf life is 24 hours. Soup can be frozen in ice cube trays.
