In the wild, a hedgehog is opportunistic and will eat many things, but the majority of their diet comprises insects.
Our suggestion is to feed Exotic Nutrition Hedgehog Complete. Keep this diet available at all times. You may also offer Exotic Nutrition Canned Insect-Eater Diet in order to offer variety, this food contains 3 types of whole cooked insects.
As insectivores, hedgehogs need a diet that is high in protein and low in fat. They also require chitin, which comes from the exoskeleton of insects; fiber in the diet may substitute for the chitin component. There are prepared foods specifically for pet hedgehogs and insectivores, including foods made from insect components. Exotic Nutrition's Hedgehog Complete is one such diet. It was formulated specifically for hedgehogs, and contains dried mealworms which contain chitin. Also available are alimentary powders to sprinkle on other food which provide chitin and other nutrients, hedgehog booster is one such product. Hedgehog caretakers should read labels on packaged food to ensure a basis of protein, rather than a basis of carbohydrate.
Pet hedgehogs may eat such table foods as cooked, lean chicken, turkey, beef or pork (in moderation due to fat content). Hedgehogs will often eat small amounts of vegetable and can be given small amounts of fruit as treats . Baby food is a common way to feed treats. Hedgehogs are lactose-intolerant and will have stomach problems after consuming most dairy products, though occasional plain lowfat yogurt (yogurt contains bacteria that naturally process lactose) or cottage cheese seem to be well tolerated. Sugar intake should be restricted to fruits, avoid any treat with added sugar.
Fresh, canned, or freeze-dried mealworms, waxworms, and crickets are appropriate as limited treats though in moderation as many feed insects are high in fat. Hedgehog caretakers should avoid bait-shop or wild caught insects, which may be contaminated with insecticides.
Hedgehogs can easily become obese. If a pet hedgehog appears to be gaining too much weight, it is important that the hedgehog’s caretaker cut back on high fat foods and increase exercise. Hedgehogs vary in size so there is no "goal weight" for a hedgehog, but if they can no longer roll completely into a ball it is a pretty clear sign of obesity. Many people believe that there is a relation between a high-fat diet and fatty-liver disease in hedgehogs.
Due to their mouth shape hedgehogs should not be fed any nuts. Nut butters are acceptable, but are very high in fat so they should probably be avoided. Hedgehogs should never be fed avocados, onions, grapes or raisins, chocolate, any raw meat or egg yolks, or any canned or processed food.
