Ferrets are obligate carnivores and therefore require a diet high in protein and low carbohydrates. They need meat for protein to help maintain muscles and they need fat to provide their energy needs. There are many available kibble choices on the market. To provide the best for your ferret be sure to read the label to ensure there is at least 35-40% protein. The first item on the label should always be meat. Another option for feeding ferrets is offering a whole-prey diet which consists of thawed frozen rodents, quail, rabbit and chicks.
How often should you feed your ferret? Most healthy ferrets are often allowed to "free feed." That means they have food available for them at all times.
Treats to avoid: Chocolate, Raisins, Fruits and Vegetables
And of course water should be kept available at all times as well either by bowl, water bottle or both.
