Your veterinarian can give you the best advice in regard to your ferret's condition and the treatment options available. The important thing to remember is that neither insulinoma nor adrenal tumor is an automatic death sentence. Nutrition Ferrets are obligate carnivores. This means they need meat-based diets to stay healthy. Because ferrets do not have cecums or ileocolic valves, they are physically unable to digest fruits and vegetables, or to get the nutritional value out of pelleted food that is not animal based.
Ferrets have three to four hour digestive tracts.
This means that three hours after they eat, they pass the waste from that meal. This requires ferrets to eat frequently throughout the day. They should have free access to food unless there is some special circumstance. Ferrets who get out of their cages to run and play on a regular basis will rarely develop weight problems provided they are being fed a balanced ferret diet. Ferret food is available at pet supply stores, but be careful, not all ferret food is created equal.
