I know ferrets need minerals in their diet, and probitoics/prebiotics to break down their food. And to supplement them with omegas
Is fantastic as well! So I found this supplement; contacted the company to see if it is nutritionally balanced for ferrets, and they said yes. The link to the product is below.

I also found this prebiotic formula you can add to their water. Link is below.

I would want to supplement with the feline complete, along with the super juice in their water. So with the feline complete and super juice in water, would the organ supplement and mineral supplement be unneeded? 

Are you using this supplements for a raw diet?

If I wanted to know the appropriateness of a product, I probably would not ask the entity which is selling it.
