Recommended Diet for Pygmy Hedgehogs: A Guide for Owners and Veterinarians
Pytheas the Greek explorer once referred to hedgehogs as "walking pincushions," but to owners and veterinarians, they are unique insectivores with specific nutritional needs. Proper nutrition is the cornerstone of a hedgehog's health and longevity.

1. Natural Diet and Classification
In the wild, African Pygmy Hedgehogs are primarily insectivores, but they are also opportunistic omnivores. Their natural diet includes:

Insects and invertebrates (beetles, caterpillars, earthworms).
Small vertebrates (small lizards, frogs).
Occasional fruits, roots, and fungi.
2. Key Nutritional Requirements
Hedgehogs require a diet high in protein and low in fat. Because they are prone to obesity, calorie control is essential.

Protein: Should be around 30-50% (on a dry matter basis). High-quality animal protein is preferred.
Fat: Should be kept low, ideally between 10-15%. Excess fat leads to hepatic lipidosis (fatty liver disease) and obesity.
Fiber: Essential for digestion, ideally 7-10%. Chitin from insect shells provides a natural source of fiber.
3. Recommended Foods
Commercial Hedgehog Food: Nowadays, there are specialized pellets formulated for hedgehogs. However, if unavailable, high-quality Low-Fat Cat Food (Senior or Weight Management formulas) can be used as a substitute.
Insects: Mealworms, crickets, and dubia roaches should be provided as supplements. Note: Insects should be "gut-loaded" (fed nutritious food) before being given to the hedgehog.
Fresh Foods: Small amounts of cooked unseasoned chicken, scrambled eggs, or safe fruits/vegetables (like apples or carrots) can be offered as treats.
4. Foods to Avoid
Dairy Products: Hedgehogs are lactose intolerant; milk can cause severe diarrhea.
Hard Foods: Raw carrots or nuts can get stuck in the roof of their mouth.
Sticky/Stringy Foods: Raisins or dried fruits can cause choking or dental issues.
Seasoned/Processed Foods: Avoid anything with added salt, sugar, or preservatives.
5. Feeding Management
Frequency: Hedgehogs are nocturnal. It is best to feed them once a day in the evening.
Water: Fresh, clean water must be available at all times. A heavy ceramic bowl is often better than a dropper bottle to prevent dental injury and ensure adequate hydration.
Weight Monitoring: Regularly weigh your hedgehog. If you can no longer see their face when they ball up, they may be overweight.

Summary for Veterinarians
When examining a hedgehog, clinicians should assess the body condition score (BCS) and discuss the diet with owners. Common nutritional-related issues include Obesity, Metabolic Bone Disease (MBD) (due to improper Calcium:Phosphorus ratios in an all-insect diet), and Dental Disease.
