Understanding the Hedgehog's Natural Diet
Wild hedgehogs are primarily insectivores, meaning their natural diet consists mainly of invertebrates. Their foraging habits lead them to consume a wide variety of small creatures found on the ground, especially during their active nocturnal hours. This natural food source is vital for their health and survival.
The backbone of a hedgehog's diet includes beetles, caterpillars, earwigs, slugs, snails, and earthworms. They also opportunistically feed on fallen fruit and berries, and occasionally small vertebrates like frogs or mice if the opportunity arises. Identifying wildflowers in the UK can sometimes reveal habitats rich in insect life, indirectly indicating areas where hedgehogs might find ample food.
Invertebrates provide the essential proteins, fats, and nutrients that hedgehogs need. For example, beetles and their larvae are rich in protein, while slugs and snails offer calcium. The sheer variety in their natural diet helps ensure they receive a balanced intake of vitamins and minerals necessary for maintaining their prickly defence, reproductive health, and energy levels for their nightly foraging.
The population of hedgehogs in the UK has seen a significant decline, with estimations suggesting numbers are lower than previously thought. Factors such as habitat loss and a reduction in their natural food sources, particularly invertebrates due to pesticide use and changes in land management, are major contributors. Ensuring hedgerows and natural areas are preserved supports their ability to find sufficient food.
It's important to remember that hedgehogs have specific dietary needs. While their natural diet is diverse, offering certain supplementary foods needs careful consideration to avoid harming them. This is where understanding what food do hedgehogs eat extends beyond just their wild foraging habits.
Supplementary Feeding: What Garden Hedgehogs Can Eat
When supporting wild hedgehogs in your garden, providing supplementary food can be a lifeline, especially during dry spells or when natural food is scarce. However, it is crucial to offer only appropriate items. The most recommended supplementary food for hedgehogs is a good quality, plain, dry cat or dog food. Look for options that are high in protein and low in fat.
Wet cat or dog food can be offered occasionally but should not be the main source of supplementary food due to its higher water content and potential to cause digestive upset. Always ensure any food provided is free from artificial colours, flavours, and added sugars. Avoid feeding milk, as hedgehogs are lactose intolerant and it can lead to severe digestive problems and dehydration. This is a common misconception about what food do hedgehogs eat.
You might wonder, 'Can I feed hedgehogs mealworms?' While hedgehogs do eat insects, including mealworms, in the wild, feeding them exclusively or in large quantities as a supplement can be detrimental. Mealworms are high in phosphorus and low in calcium, which can lead to serious bone health issues like metabolic bone disease over time. If you choose to offer them, it should be as a very occasional treat and in small amounts, ideally combined with a calcium supplement if advised by a wildlife expert.
The Dangers of Unsuitable Foods
Feeding hedgehogs inappropriate items can cause more harm than good. Beyond milk, other common mistakes include offering bread and seeds, which offer little nutritional value and can fill their stomachs without providing necessary energy, leading to malnutrition. Nuts, including peanuts, can also pose a choking hazard or contribute to blockages, so these should also be avoided.
It's also worth noting that while some bird feeder ideas might appeal to other garden visitors, they are not suitable for hedgehogs. Items like suet blocks or seed mixes designed for birds do not align with a hedgehog's dietary requirements and can even be harmful. If you're setting up a feeding station for hedgehogs, ensure it's designed to keep other garden visitors, like cats or foxes, away from their food.
The decision to feed hedgehogs is a significant one that requires commitment to providing the right sustenance. This care can contribute to the health of local hedgehog populations, which is important given the challenges they face.
Providing safe, appropriate food is one of the most direct ways you can help support struggling wild hedgehog populations in your garden.
Hydration and Feeding Station Setup
Water is just as crucial as food for hedgehogs. Always provide a shallow dish of fresh, clean water. This is particularly important during warm, dry weather when natural water sources may disappear. Ensure the dish is stable and not too deep, so hedgehogs can drink without risk of falling in and drowning.
Placing a feeding station for hedgehogs in a quiet, sheltered spot in your garden is advisable. This helps protect them from predators and other garden animals, such as cats, which can be aggressive towards hedgehogs and steal their food. A simple DIY feeding station can be constructed from a large plastic storage box or a wooden structure with an entrance hole large enough for a hedgehog but too small for larger animals.
When and How to Feed
Hedgehogs are nocturnal, so the best time to put out food and water is in the evening, just before dusk, when they typically begin their foraging. Remove any uneaten wet food in the morning to prevent it from spoiling or attracting flies. Dry food can be left out overnight. If you are providing food regularly, aim to do so at a consistent time each evening.
When offering dry food, a small amount is usually sufficient. A typical serving might be around 2-3 tablespoons of dry cat or dog food per hedgehog. If you see multiple hedgehogs, you may need to increase the quantity. It’s often best to place food in separate, shallow dishes to avoid competition and allow all hedgehogs to feed peacefully.
Beyond food and water, creating a safe environment is paramount. This includes ensuring access to safe nesting sites. Think about how to build a home for hedgehogs by leaving areas of your garden a little wild, with log piles or leaf litter, which can provide shelter and attract insects. Considering the wider habitat can significantly benefit their well-being.
Ensure any feeding station is easily accessible for hedgehogs but difficult for larger predators like foxes or domestic cats to access.
By understanding the specific dietary needs of hedgehogs and setting up appropriate feeding arrangements, you can make a positive impact on their survival rates in urban and suburban environments. Their well-being depends on thoughtful intervention.
Identifying and Helping Sick or Injured Hedgehogs
While a healthy hedgehog is typically active and spiny, recognising signs of distress or illness is crucial for knowing when intervention is necessary. If you find a hedgehog out during the day, it might be unwell, dehydrated, or injured. Although hedgehogs do mate and have young during specific seasons, a lone hog during daylight hours warrants attention.
Common signs of a sick or injured hedgehog include lethargy, visible wounds, maggots on the body, wobbling or uncoordinated movement, flies buzzing around them, or a sunken appearance. If a hedgehog appears distressed, it is important not to disturb it unnecessarily. However, if it is in immediate danger (e.g., in the middle of a road) or clearly unwell, you may need to act.
When to Intervene
If you find a hedgehog that is underweight (less than 500g, roughly the size of a mug before hibernation, but this can vary), or appears sick or injured, the best course of action is to contact a local wildlife rescue organisation. They have the expertise and resources to provide appropriate care. Do not attempt to treat the animal yourself without professional advice.
When you do contact a rescue, they will likely ask about the hedgehog's condition, its location, and when you found it. They may also give you preliminary advice on what to do, which often includes placing the hedgehog in a secure box with a warm water bottle (covered with a towel) and a shallow dish of water, but never food initially, as this can be harmful if they are too sick to digest it.
It is vital to distinguish between a hedgehog needing help and one simply foraging. Never assume a hedgehog needs rescuing just because it is outside. Observe from a distance first. If you are concerned about the general health of hedgehogs in your area, consider creating a 'hedgehog highway' by making small gaps in fences to connect gardens, allowing them to roam and find food and mates more freely.
By learning what food do hedgehogs eat and recognising when they are in distress, you can provide effective support. This awareness helps protect these beloved garden visitors and contributes to wider conservation efforts.
