Mine get a mix of dry foods (premium cat food, premium, small kibble
puppy food and Spike's Delight Hedgehog food.) They get 3-10 mealies a week and about 2-3 crickets per night. The mealies are live, but the crickets are freeze-dried from Flukers.
They occasionally get unseasoned cooked egg, meats (salmon, chicken, turkey) and fruits and veggies (berries, melon, peach, pear, tomato, sweet potato, squash, beans, peppers, etc.)
One of the best sites I have seen on hedgehog nutrition is by Laura Roberts. You can find it at:
http://www.angelfire.com/wa2/comemee.../hhcare7A.html This sites includes information on what to look for in the foods you feed your hedgehog as well as the nutritional content in many foods that are commonly fed to hedgehogs.
It is important to realize that there really hasn't been a lot of research done to determine what is best for our quilly little friends. Just because a hedgehog food is formulated for hedgehogs does not mean that it is any more suitable for hedgehogs than a PREMIUM brand of cat food (Vitakraft is a good example of a hedgehog food that although marketed for our pet hedgehogs, is not appropriate.)
