Understanding the Natural Hedgehog Diet
For wild hedgehogs, a healthy diet is one rich in protein and naturally sourced from their environment. Primarily, they are insectivores, meaning insects form the bulk of what do hedgehogs eat. This includes a variety of invertebrates found on the ground and in vegetation, such as beetles, caterpillars, earthworms, slugs, and snails. A single hedgehog can consume hundreds of insects each night, playing a crucial role in natural pest control within gardens and meadows across the United Kingdom. Their foraging behaviour is nocturnal, making them active hunters under the cover of darkness.
Beyond insects, their diet can also extend to other small creatures. If the opportunity arises, hedgehogs may also eat small frogs, slow worms, or even fallen bird eggs or nestlings, although this is less common. They are opportunistic feeders, adapting to what is available in their immediate surroundings. The presence of a diverse range of invertebrates signifies a healthy ecosystem capable of supporting a thriving hedgehog population. A garden that attracts a wide array of insects is therefore a naturally appealing habitat for these spiky mammals.
It's important to recognise that the hedgehog's natural inclination is to forage for this varied, protein-packed food. This instinct drives their behaviour and ensures they receive the necessary nutrients for survival, hibernation, and reproduction. Understanding this natural dietary baseline is the first step in determining how we can best assist them when their natural food sources become scarce.

Insects: The Cornerstones of a Hedgehog's Meal
The backbone of a wild hedgehog's sustenance lies in the diverse array of invertebrates it can find. Earthworms are a particular favourite, providing essential moisture and nutrients. Slugs and snails, while sometimes carrying parasites, are also part of their natural diet. Hedgehogs have a remarkable ability to process and consume snails, often breaking them down effectively. Beetles, earwigs, and millipedes offer crunchy textures and vital protein. Caterpillars are another common find, especially during their active seasons. The variety ensures a balanced intake of fats, proteins, and minerals.
What About Other Food Sources?
While insects are preferred, hedgehogs are not strictly limited to them. They will opportunistically consume small vertebrates like frogs or slow worms if encountered. In urban or suburban environments, they might scavenge fallen fruits or berries, though these are not a primary food source and offer little nutritional value for their needs. The presence of bird feeders can sometimes lead to hedgehogs scavenging dropped seeds or other food meant for garden birds. However, this is not ideal as processed foods or excessive grains can be harmful.
Hydration: What Do Hedgehogs Drink?
Just as critical as their food is access to fresh water. What do hedgehogs drink is far simpler: water. They require a reliable source of clean, fresh water, especially during warmer months and periods of drought when natural puddles or dew might be scarce. Hedgehogs are susceptible to dehydration, and readily available water is essential for their survival and overall health. They typically drink in the early morning or late evening, often after their nocturnal foraging activities.
Access to fresh water is as vital as any food source for a healthy hedgehog population.
Natural water sources such as shallow ponds, streams, or even large, clean puddles can suffice if available and safe. However, many garden environments lack these natural features, particularly during dry spells. This is where garden owners can make a significant difference. Providing a dedicated water dish can be a lifeline for thirsty hedgehogs, as well as for other garden visitors like birds and insects. It's a simple yet profoundly effective way to support local wildlife and ensure these animals can stay hydrated.
Providing Safe Drinking Water
To offer water, a shallow, sturdy dish is ideal. A plant saucer or a purpose-made wildlife water bowl works well. It should be placed on a level surface in a safe location, away from potential predators or hazards. Importantly, the water should be cleaned and refilled daily. This prevents stagnation, the build-up of harmful bacteria, and reduces the risk of disease transmission. Ensure the dish is not too deep to prevent hedgehogs, especially young ones, from drowning. A few pebbles or a small ramp can help if the sides are steep.
Always clean water dishes thoroughly with hot water to remove any residue, and refill daily to ensure it remains fresh and appealing.
Avoiding Contaminated Water
Hedgehogs can be harmed by polluted water sources. Avoid placing water dishes near areas where pesticides or herbicides might have been used, as runoff can contaminate the water. Similarly, ensure any water sources aren't too close to busy roads or areas with high human or pet traffic, which could disturb them. Clean water is paramount; murky or stagnant water can lead to illness. The goal is to mimic a clean, natural water source as closely as possible, ensuring it is both accessible and safe for them.
What NOT to Feed Hedgehogs
When considering how to supplement a hedgehog's diet, it is crucial to understand what foods are harmful. The most common mistake people make is offering milk, whether cow's milk or even goat's milk. Hedgehogs are lactose intolerant, and milk can cause severe digestive upset, leading to diarrhoea and dehydration, which can be fatal. This is a widely held misconception that needs to be addressed. Always ensure any supplementary food or water is appropriate for wild hedgehogs and avoid anything that might cause them harm.
Commonly Mistaken Food Items
Beyond milk, other foods often mistakenly offered can be detrimental. Bread is another item that should be avoided. It offers very little nutritional value and can fill a hedgehog's stomach, leading them to consume less of their natural, protein-rich diet. In large quantities, it can also contribute to weight gain and associated health problems. Similarly, processed foods, cooked foods, nuts, and seeds are not suitable. These can be difficult to digest, lack the essential nutrients hedgehogs require, and can even pose choking hazards or internal damage.
The dangers of feeding inappropriate foods outweigh the perceived benefits.
Why Avoid Certain Foods?
The digestive systems of hedgehogs are specifically adapted for a diet of insects and other small invertebrates. Foods high in carbohydrates, sugars, or fats, like those found in human food scraps, can disrupt their delicate balance. This can lead to obesity, dental problems, and a weakened immune system, making them more susceptible to diseases. For wild animals, maintaining a healthy weight and strong immune system is critical for survival, especially during hibernation. Providing incorrect food can actively hinder their ability to thrive and reproduce.
The Dangers of Parasites from Food
Furthermore, certain food items, like raw meat or eggs not intended for wildlife, can carry pathogens or parasites that hedgehogs might not be equipped to handle. While hedgehogs naturally consume snails, which can sometimes carry lungworm, their bodies are adapted to this to some extent. However, introducing new, potentially contaminated sources of food can overwhelm their natural defences. It's always best to stick to known safe options or, ideally, encourage a garden environment that naturally supports their dietary needs.
Supplementing a Hedgehog's Diet Safely
When natural food sources are scarce, particularly during dry spells or prolonged cold weather, offering supplementary food can be a lifeline for hedgehogs. The most recommended food is a specifically formulated hedgehog food, available from pet shops or wildlife food suppliers. These products are designed to meet their nutritional requirements, offering the right balance of protein and fat. If hedgehog-specific food is unavailable, a good quality, meat-based cat or dog food (dry or wet, with no fish or added vegetables) can be a suitable alternative. Ensure it contains at least 20% protein and less than 10% fat.
A small amount of suitable food, offered occasionally, can make a significant difference.
What is the Best Food to Offer?
Hedgehog food is the ideal choice. It mimics their natural diet in terms of protein content and essential nutrients. If using cat or dog food, check the ingredients list carefully. Avoid anything containing fish, as the strong smell can be off-putting to hedgehogs and some argue it’s not ideal for their diet. High-quality, plain meat-based options are best. Always serve food in a shallow dish, and remove any uneaten food promptly the next morning to prevent it from becoming stale, attracting pests, or harbouring bacteria. Small, dry cat biscuits can also be a good option if they are meat-based and have a suitable protein content.
Place food and water dishes in a quiet, sheltered spot in your garden, such as near a hedge or under a bush, to give hedgehogs a sense of security.
Creating a Hedgehog-Friendly Garden
Beyond direct feeding, the most impactful way to help hedgehogs is to make your garden a haven for them. This involves providing habitats and encouraging their natural food sources. Planting native wildflowers and creating insect-rich habitats, such as log piles or compost heaps, will naturally attract beetles, worms, and other invertebrates. Avoid using slug pellets or pesticides, which can poison hedgehogs directly or indirectly by reducing their food supply. Leave areas of your garden a little wild, with leaf litter and undisturbed vegetation, as these provide shelter and hunting grounds.
The Importance of Hedgehog Houses
A hedgehog house can offer a safe place for hedgehogs to nest, rest during the day, or hibernate during winter. These are typically wooden boxes with a small entrance hole, often covered with leaves or bedding material. Ensure the house is placed in a quiet, sheltered location and is well-camouflaged. It’s important to check these houses periodically, but avoid disturbing any occupants. Creating a comprehensive hedgehog-friendly environment ensures they have access to both natural food and drink, as well as safe refuge, promoting their long-term well-being.
Supporting Hedgehogs Through Seasonal Changes
Hedgehogs face different challenges throughout the year, and understanding these seasonal changes can help us provide more targeted support. In spring, after emerging from hibernation, they are often thin and in need of sustenance. Providing food and water during this period is particularly beneficial. Summer is their active breeding season, requiring plenty of food to support the growth of hoglets. Autumn is a critical time as they need to build up sufficient fat reserves for hibernation. A consistent supply of food and water throughout this period is vital for ensuring they enter hibernation in good condition.
The transition into hibernation is a critical phase for a hedgehog's survival.
Autumn Preparations for Hibernation
As temperatures drop and days shorten, hedgehogs instinctively begin to prepare for hibernation, which typically occurs from November through to April. They need to consume a high-energy diet to accumulate the necessary fat stores. This is often when garden feeding can be most crucial. Ensure their food and water sources are consistently available and replenished. A well-fed hedgehog entering hibernation has a much better chance of surviving the cold months and emerging healthy in the spring. Monitor for hedgehogs that appear underweight or are active very late into the autumn, as they may require extra assistance.
Spring Emergence and Recovery
When hedgehogs emerge from hibernation in spring, they are often weak and ravenously hungry. Their natural food sources may not yet be abundant, so providing supplementary food and fresh water is highly beneficial during this recovery phase. This helps them regain strength and prepare for the breeding season. Observe their activity; if a hedgehog is active during daylight hours in spring and appears lethargic, it might be unwell or struggling to find food, warranting gentle, supplementary feeding.
The Role of Wildlife-Friendly Gardens
Ultimately, the most sustainable way to support hedgehogs is by creating a garden that caters to their natural needs year-round. This means promoting insect populations by avoiding chemical treatments and providing diverse habitats. Allowing your garden to be a little 'wild' with leaf litter, compost heaps, and uncut areas offers shelter and natural food. Ensuring continuous access to clean water, especially during dry spells, is also paramount. By fostering an environment where hedgehogs can find their own food and drink, you contribute to their long-term survival and the health of your local ecosystem.
