I, too, read Dr. Susan Brown's comment on whipping cream. If you read the response carefully, she specifically says not to use the canned kind of whipping cream. We have a 9 year old female with insulinomas and have been using a small amount of heavy whipping cream mixed into chicken baby food to add fat and protein to help balance the insulinomas. The whipping cream is the kind that comes in a carton, and it does not contain sugar. Since we started doing this, Tabu's insulinoma episodes have stabilized. Also, it is an excellent way to get her medications down. We had been using Nutrical, but it definitely contains sugars so that has been eliminated. I have noticed that several people have posted to boards saying that they have had difficulty getting their ferrets to take other protein foods that help with insulinomas, and I think that the whipping cream would help. I don't "whip" the cream; I just shake it up really well in the container. I limit her intake to about 1 teaspoon a day. Tabu has gained weight since doing this, and she does not get runny poops. I totally concur about watching for sugars with ferrets with insulinomas, but I disagree that heavy whipping cream is a problem. "It's just another day in paradise!" [Posted in FML issue 1757]
