I have been using various baby formulas in my duck soup for about a year now. They aren't nearly as sweet as things like ensure and the ferrets switched over without a problem. Since I never seem to use all of it, I finally tried the powdered formulas available and mix it up as needed. It is so much more convenient for me that way. And it seems to work just fine. Freds had a bought with his ulcers flaring up and it got weight back on him really well.
