What Do Hedgehogs Eat? A Fact-Checked Guide to Wild and Pet Diets

Wild diet: 70-80% invertebrates · Pets main food: High-quality kibble + insects · Safe produce: Tiny portions only · Key warning: No milk, nuts, or hard raw veg

What wild hedgehogs actually eat

In the wild, hedgehogs are generalist insectivores — their digestive system is built for chitin-rich invertebrates, not plant matter. The UK-based conservation group Hedgehog Street (wildlife charity) reports that their diet is mostly made up of invertebrates: worms, beetles, slugs, caterpillars, earwigs, and millipedes. These provide the high protein and low carbohydrate profile hedgehogs evolved on.

• Beetles and earthworms are the top two food items by frequency (Hedgehog Street)
• Slugs and caterpillars are also common, especially in damp conditions
• Less frequently: carrion, frogs, baby rodents, baby birds, birds’ eggs, and fallen fruit

The implication: wild hedgehogs are not designed for fruit or grains. Their occasional fruit consumption is opportunistic, not nutritional, and never makes up a meaningful part of their diet.

Key invertebrate prey by occurrence

Here’s a breakdown of the most common invertebrate prey and their role in a wild hedgehog’s diet.

What this means: if you’re feeding a wild hedgehog in your garden, the best offering is unseasoned cat food or specific hedgehog food — not bread or milk, which cause severe digestive distress.

What pet hedgehogs should eat

Pet hedgehogs have the same biological constraints as their wild cousins, but their activity levels are far lower — making diet composition and portion control absolutely critical. VCA Hospitals (veterinary network) advises that the staple should be high-quality hedgehog food mixed with high-quality, low-fat cat food. This provides balanced protein and fat without the excess carbohydrates that lead to obesity.

Six key foods, one pattern: insects are supplemental, kibble is foundational, and produce is strictly limited.

Safe fruits and vegetables — with major caveats

Multiple sources agree that fresh produce can be offered, but only in very small amounts. Hedgehog Program (specialist care guide) states that vegetables and fruit should never exceed a few percent of the diet. Their safe list includes carrot, courgette, and apple without seeds. Olympia Veterinary Hospital (veterinary practice) adds apples, bananas, berries, melons, tomatoes, green beans, and cooked squash.

But here’s where advice diverges sharply. Pro Igel (German hedgehog conservation group) explicitly warns against feeding any fruit, vegetables, cheese, nuts, quark, or yoghurt to hedgehogs. They recommend moist cat or dog food, eggs, poultry meat, minced meat, and bred feed insects as suitable items. This stricter position reflects a precautionary approach: hedgehogs simply don’t need produce, and any potential benefit is outweighed by the risk of digestive upset or obesity.

The pattern: produce is a garnish, not a meal component. If you offer fruits or vegetables, keep portions to a pea-sized amount once or twice a week at most, and remove uneaten pieces within hours to prevent spoilage.

Foods to avoid — the danger list

Olympia Veterinary Hospital lists a long set of banned items: raw meat and eggs, milk, nuts, seeds, hard foods such as raw carrots and dried vegetables, avocados, chocolate, garlic, onions, starchy foods like corn and potatoes, xylitol, lettuce, and celery. Many of these cause either choking risks (hard foods), toxicity (chocolate, garlic, xylitol), or severe digestive problems (dairy).

Confirmed dangerous foods at a glance

Why this matters: many of these “human foods” appear in kitchens daily, and owners may assume a tiny bit won’t hurt. But a hedgehog’s digestive system is radically different from ours — even a small piece of avocado can be toxic.

Feeding schedule and portion tips

Consistency and control are the twin pillars of feeding a pet hedgehog. VCA Hospitals recommends feeding once daily, in the evening, matching their nocturnal activity pattern. Kibble should be left in a bowl for the hedgehog to graze on overnight, but uneaten wet food must be removed after a few hours to prevent spoilage.

• Portion size: 1-2 tablespoons of kibble per day, depending on size and activity
• Insects: 2-3 times per week, 5-10 mealworms or 2-3 crickets per serving
• Treats (fruit/veg): once or twice a week, pea-sized portion
• Always provide fresh water in a heavy ceramic bowl (not a bottle — hedgehogs struggle with sipper tubes)

The trade-off: owners want to spoil their pets with treats, but every extra gram of sugar or starch moves the hedgehog closer to fatty liver disease, dental problems, and shortened lifespan.
