ferret only will eat dog food

Question
I have had my 9 month old ferret for 3 weeks now and I also have 2 large dogs. My ferret will only eat dog food, I have tried the marshells ferret food 8 in 1 canned ferret food also have made a soup with it and she will not eat any of it. She has pretty bad diarrhea so I am making sure she has lots of water and I put her away when the dogs are eating. But she still won't eat regular food. Ps we rescured her and they were feeding her cat food. How do I get her to eat ferret food without depriving her of food because I know she needs to eat.

Answer
First, she needs to get to the vet for the diarrhea.  Since a ferret is so small, it doesn't take a lot of liquid loss to cause a problem.  Next, if she was on cat food, try a high quality kitten food and keep the dog food away.  Kitten food it better than dog food.  Mix in a high quality ferret food with the kitten food (Totally Ferret or Natural Gold)to switch her over.
