Understanding Hedgehog Dietary Needs
Deciding what to feed hedgehogs, particularly wild ones visiting your garden, requires understanding their natural diet. Hedgehogs are primarily insectivores, meaning their main food sources are invertebrates like beetles, caterpillars, slugs, snails, and earthworms. They will also consume small amounts of fallen fruit, fungi, and occasionally carrion. In the wild, they spend many hours foraging, consuming a varied and protein-rich diet. When considering supplementary feeding, the goal is to mimic this nutritional profile as closely as possible.
In recent years, wild hedgehog populations have seen a significant decline across the UK. Factors contributing to this include habitat loss, fragmentation, and reduced availability of their natural food sources due to pesticide use and changes in land management. Supplementary feeding can offer a vital lifeline, especially during dry spells when natural food is scarce, or in the autumn as they build up reserves for hibernation. It's important to approach feeding responsibly, ensuring the food provided is beneficial and does not cause harm.
The key principle when determining what to feed hedgehogs is to offer high-protein, low-fat options. This aligns with their natural diet and supports their energy needs without contributing to obesity, which can be detrimental to their health and ability to hibernate. Offering food can also encourage hedgehogs to visit your garden, providing an opportunity to observe these fascinating creatures and contribute to their conservation.
Natural Foraging Behaviour
Hedgehogs are nocturnal foragers, using their keen sense of smell to locate prey. Their natural diet is diverse, reflecting the variety of invertebrates available in their environment. This includes a wide range of insects, spiders, and worms, which are excellent sources of protein and essential nutrients. They are opportunistic feeders, and their diet can shift seasonally based on what is most abundant. Understanding this natural behaviour helps us make informed choices about supplementary feeding, ensuring we provide foods that are nutritionally appropriate.
Safe Foods for Feeding Hedgehogs
When you decide to offer food to hedgehogs, selecting the right items is paramount. The most recommended food is specifically formulated high-quality hedgehog food, often available from pet shops or specialist wildlife suppliers. This food is designed to meet their precise nutritional requirements, offering a balanced mix of protein and fats. If specific hedgehog food is unavailable, some alternatives can be considered, but with caution.
Cooked, unseasoned meat or chicken cat food (wet variety) is often cited as a suitable option. It provides essential protein. However, always ensure it contains a high meat content and is free from artificial colours, flavours, and added sugars. Dry cat or dog biscuits can also be offered, but they must be plain and low in fat; avoid those with added vegetable proteins or high carbohydrate content. These dry options should always be offered with a shallow dish of fresh water, as they can be dehydrating.
A small amount of fruit, such as unsweetened apple or berries, can be given occasionally as a treat, but it should not form a significant part of their diet due to its sugar content. Similarly, a few unsalted, unseasoned peanuts might be offered, but avoid peanut butter as its consistency can be a choking hazard and it's very high in fat. Always ensure all offered food is placed in a shallow dish in a quiet, safe location, away from potential predators and where cats and dogs cannot easily access it. Remove any uneaten food the following morning to prevent it from becoming stale or attracting pests.
What Not to Feed Hedgehogs
It is just as important to know what foods to avoid when feeding hedgehogs. Many common human foods can be harmful, leading to digestive upset, malnutrition, or even more serious health issues. Milk and dairy products are a common mistake; hedgehogs are lactose intolerant, and feeding them milk can cause severe diarrhoea and dehydration. Always provide fresh, clean water instead.
Bread is another food that should never be offered. It offers very little nutritional value, is high in carbohydrates, and can fill a hedgehog's stomach, leading them to forgo more nutritious food sources. It can also lead to weight gain and associated health problems. Other items to strictly avoid include: cooked meats with added salt or seasonings, processed foods, nuts and seeds in large quantities (especially salted or flavoured varieties), and any food containing artificial sweeteners or preservatives. These can all be toxic or detrimental to a hedgehog's delicate digestive system.
Never feed hedgehogs anything that is spicy, salty, or contains artificial ingredients.
If you are unsure about a specific food item, it is always best to err on the side of caution and avoid offering it altogether.
Setting Up a Hedgehog Feeding Station
Creating a safe and effective feeding station for hedgehogs is crucial to ensure they benefit from the food provided and are protected from hazards. A well-designed station will deter larger predators like foxes and domestic pets, while also keeping the food clean and dry. The location is key; choose a quiet, sheltered spot in your garden, perhaps near a hedge or under a bush, where hedgehogs feel secure.
A simple feeding station can be made from an upturned plastic storage box with an entrance hole cut into one side, large enough for a hedgehog to pass through but small enough to deter larger animals. Alternatively, a sturdy wooden structure or even just a heavy paving slab placed over a shallow dish can provide adequate shelter. Ensure there are no sharp edges on any DIY structures. The station should be cleaned regularly to prevent the build-up of bacteria, which could make hedgehogs ill. A shallow, heavy dish is ideal for the food itself, preventing it from being tipped over easily.
Always provide fresh, clean water alongside the food. A shallow, stable water dish is essential, especially during dry periods. Remember that offering food should be a supplementary measure, not a replacement for a hedgehog's natural diet. The aim is to help them, not make them reliant on human handouts, which can disrupt their natural foraging behaviours.
Frequency and Quantity of Food
When it comes to how much and how often to feed hedgehogs, consistency is more important than volume. If you choose to feed them, aim to put out a small amount of food each evening, just before dusk, which is when they become active. This provides a reliable food source for them. A typical serving might be a small handful of dry hedgehog food or cat biscuits, or a small amount of wet cat food. Avoid overfeeding, as this can lead to waste, attract unwanted pests, and contribute to obesity in the hedgehogs.
Monitor the food to gauge if it's being eaten. If food is consistently left uneaten, you may be offering too much, or the type of food may not be appealing. It's also a good idea to clean up any uneaten food the next morning to maintain hygiene. If you are only able to feed intermittently, that is still better than not feeding at all, as any supplementary food can make a difference. The presence of hedgehogs in your garden can be an indicator of a healthy local ecosystem, but if you see them struggling or appearing unwell, it may be worth contacting a local wildlife rescue organisation for advice.
The most crucial aspect of feeding is providing access to fresh water.
