Hedgehog care guide

How to help a helpless or orphaned wild hedgehog properly – when it needs help, how to stabilise it, what it eats, how to hand-feed hoglets, plus hygiene and Finnish law. Read this before you take a hedgehog into care.

01

When does a hedgehog need help?

The hedgehog is nocturnal. One out in daylight usually has something wrong – but a healthy adult active at night is left alone. Finnish law allows taking a wild animal into possession only if it is injured, sick or otherwise helpless.

Needs help

  • Moving or lying out in the middle of the day
  • Lying still or "sunbathing" in the open – hedgehogs don't sunbathe; it signals serious illness
  • Wobbling, staggering or walking in circles (circling = eye or ear injury)
  • Fly eggs (tiny rice-like grains) or maggots – an emergency; larvae eat living tissue within a day
  • Visible wound, blood, or caught in netting
  • A nest of hoglets with no mother, or several hoglets together with no mother
  • Active in winter (nest destroyed or soaked)
  • An autumn juvenile clearly too small to hibernate

Leave alone

  • A healthy, brisk adult moving at night
  • A mother purposefully gathering food or nest material, out only briefly by day
  • A single, healthy weaned juvenile foraging alone
  • An intact nest – the mother returns; do not disturb
  • A hedgehog found at night that hisses and curls into a tight ball is likely vigorous – but daytime activity always overrides this
02

First aid & stabilising

Two things save a hedgehog before it reaches care: warmth and calm. Warm it first – never feed or give water to a chilled hedgehog.

Warmth + a dark, quiet box + fast to care. That is the golden rule.
03

Handling & daily care

🧤

Wear gloves

Always handle with gloves (a hedgehog can carry salmonella and ringworm). Lift with two cupped hands from underneath – don't grab from above.

⚖️

Weigh daily

Record the weight every day. The weight trend is the most important sign of whether recovery is on track.

🤫

Handle little

A hedgehog is a solitary, timid prey animal. Unnecessary handling stresses it and slows recovery.

🚪

Quarantine

Keep a new arrival separate for ~48 hours and treat it as potentially infectious.

🫧

Foaming is normal

Self-anointing (twisting to spread frothy saliva over the spines after tasting a new smell) is completely normal – not rabies. Finland is rabies-free.

💊

Deworming = the vet

Lung- and gut-worms are diagnosed from a faecal sample. The wrong or too-fast deworming can worsen things – the decision belongs to the vet.

Enclosure & hygiene

05

Feeding (weaned hedgehog)

The hedgehog is an insectivore. In the wild at least 60–80 % of the diet is insects. In care the staple is meaty (not fish-based) wet cat or dog food plus cat or hedgehog biscuits; cat food is better for its higher protein. For a weak animal start with a soft wet-food-and-water mix (but only once it is warm and rehydrated). A practical starting portion is ~20 g. Fresh water always in a shallow, non-tip dish – water is the only drink, no drinking bottles.

Never give

  • Cow's milk or any lactose – hedgehogs are lactose-intolerant; milk causes fatal diarrhoea. (The old "bread and milk" advice is wrong.)
  • Bread, grain or baked goods – no nutritional value, hard to digest.
  • Mealworms as a staple – the calcium-to-phosphorus ratio is badly skewed (~1:7–1:20) and causes Metabolic Bone Disease (MBD). The same goes for peanuts, sunflower hearts and other nuts/seeds.
  • Raw fish, salt, spices, processed meat or organs.
  • Insects caught in the wild (parasite risk).
  • Fruit or vegetables as the main diet – a hedgehog needs protein and minerals, not plants.

For extra protein use cooked, unsalted, unseasoned lean meat (chicken, turkey, minced beef) or cooked (not raw) fish.

The most important part

Hand-rearing orphaned hoglets

Feeding interval by age

AgeWeight (indicative)Feeding interval
0–3 days8–25 g~every 2 hours, night too
3 days–2 wkgrowing →~every 3 hours
2–4 wk~80–130 g~every 3–4 hours
~4 wk →solids begintapers as solids come in
07

Hygiene & your own health

The risk is manageable with simple steps – no cause for fear, but good hygiene is a must. The single most important protection is washing hands with soap immediately after handling, food dishes, or cleaning the enclosure.

08

The law in Finland

In short: helping a helpless wild hedgehog and briefly getting it to care is everyone's right and even duty – with no permit and no fee. Keeping one permanently is not allowed, and long-term or systematic rehab activity is separately regulated. When unsure, always check with the authority or a vet experienced with wildlife.
