Ferrets are obligate carnivores, meaning their diet should primarily consist of animal-based proteins. A balanced diet for ferrets includes high-quality commercial ferret food, which is specially formulated to meet their nutritional needs. It's important to choose foods that are high in protein (at least 30-40%) and low in carbohydrates, as ferrets have a short digestive tract and require easily digestible nutrients. In addition to commercial food, ferrets can benefit from occasional treats like cooked meats or raw eggs. However, avoid feeding them fruits, vegetables, or grains, as these can lead to digestive issues. Always ensure fresh water is available, as hydration is crucial for their health.
