I do a variation of the baby food gravy without the sugars and fruit because my ferret has insulinoma. I mix chicken or turkey 2nd stage Gerber baby food with Iam's canned cat food and a teaspoon of ferretone. I also insure that she gets her daily vitamin. The Gerber baby food is approved by ferret smart vet Mitsie Vargas in Winter Haven, near Tampa, FL. Dr. Vargas has performed hundreds of surgeries for insulinoma and adrenal disease.
I also insure that she gets her daily vitamin dosage. She has put on weight and is feeling much better. My vet in Clearwater, Dr. James Hughes, special ordered her some prednisone in a chewable chicken flavored morsel. This is much easier to get down her.
