Dangers and help for hedgehogs The right way to help hedgehogs
With their round beady eyes and a coat of up to 8,000 spines, hedgehogs are unmistakable. These nocturnal animals also like to pay a visit to gardens. You can do something good for hedgehogs in just a few simple steps.
Hedgehogs rest during the day and like to rummage around in the leaves at dusk and at night for their next meal. These prickly animals prefer to roam in natural gardens and on the outskirts of settlements. They hibernate from the end of October. To help hedgehogs through the winter, you can already do something for them in the fall and summer.
How to feed hedgehogs correctly The wrong food can be fatal for hedgehogs.

Offer fresh water daily, but never milk or other dairy products.

Please do not give hedgehogs any fruit or vegetables. The animals cannot digest them well.

Feed high-quality canned wet cat food with at least 60% meat content (preferably without cereals, vegetables, sugar, spices, jelly & additives). You can mix in a few oat flakes & some wheat bran.

Hard-boiled eggs or unseasoned scrambled eggs are also suitable for helping hedgehogs. Please make sure that the eggs come from animal-friendly husbandry.
Making gardens hedgehog-friendly
Hedgehogs retreat to embankments, dense hedges or piles of leaves during the day. As agricultural land spreads and gardens are often too tidy and sterile, hedgehogs lack places to hide. If you want to do something good for the animals, design your garden in a natural way. Choose native plant species and sow wild herbs and flowers to attract insects. Hedgehogs like it messy, so it's best to mow less and leave dead plants, leaves and piles of garden waste lying around - they make ideal winter quarters. You can also put up a hedgehog house.1 A wooden box at least 40 centimetres wide and long and 30 centimetres high is suitable for each hedgehog. It is important that the hedgehog house is protected from rain and wind, has an insulating and dry base and is lined with leaves. To give hedgehogs more space to roam, holes in the fence to neighboring gardens are helpful. These should be at least 13 centimetres wide and high.
Deadly danger from robotic lawnmowers and leaf vacuum cleaners
Every year, robotic lawnmowers kill many hedgehogs because they do not recognize animals as an obstacle. Hedgehogs are not flight animals; instead, they curl up into a spiky ball on the spot in the event of danger. The sharp blades of the robotic lawnmower roll over the animals and seriously injure them. If the animals survive, they often drag themselves into the bushes, where they then die in agony. Leaf vacuum cleaners and blowers are also dangerous: hedgehogs can be sucked in and killed. It is therefore best if garden owners do not use such devices. If you still want to use them, you should at least only use them during the day, as hedgehogs only come out of their hiding places at dusk. Please check the lawn, hedges and bushes before use and keep an eye on the devices while they are in use.
When does a hedgehog need help? Don't just take hedgehogs home

Hedgehogs are best kept as wild animals in the wild. It is also legally forbidden to take wild animals from the wild. You should only take in a hedgehog if it is absolutely necessary and it can be released back into the wild after successful recovery.
In these cases, a hedgehog needs help:
- It is injured, e.g. has cuts or bloody spots.
- It is ill. You can recognise sick hedgehogs by the fact that they stagger, cough or rattle, behave listlessly or are heavily infested with parasites.
- It is very young: Orphaned young hedgehogs that wander around during the day without their mother need help immediately.
- It is malnourished: Adult hedgehogs should weigh at least one kilogramme before they go into hibernation, young hedgehogs must then weigh at least 550 grams. Otherwise, the animals are dependent on supplementary feeding or must be taken into care. However, consultation with experts is always necessary here.
If hedgehogs are out and about during the day, especially from late autumn onwards, this is almost always a bad sign.
In such cases, please visit a veterinary practice or contact one of the member organisations of the German Animal Welfare Association.
