🦔 Life of a Hedgehog

Hedgehogs are small, insectivorous mammals found mainly in Europe, Asia, and Africa. Known for their spiny coat and cute, curious nature, they play an important role in controlling insect populations.

🐣 1. Birth and Early Life (0–4 weeks)

  • Gestation: About 35 days.

  • Litter Size: Usually 4–7 hoglets (baby hedgehogs).

  • Newborn Hoglets:

    • Born blind, deaf, and without spines (their spines harden within hours).

    • Weigh about 10–15 grams.

    • Completely dependent on the mother.

  • Development:

    • Eyes open after about 2 weeks.

    • Start to explore the nest and surroundings by 3–4 weeks.

    • Begin to eat solid food while still nursing.



🧒 2. Juvenile Stage (4–8 weeks)

  • Weaning: Hoglets are usually weaned by 4–6 weeks.

  • Learning: Begin to learn how to forage for insects and small invertebrates.

  • Growth: Grow quickly and start developing adult spines and features.

👨‍👩‍👧 3. Adolescence (8 weeks – 6 months)

  • Independence: By 6–8 weeks, young hedgehogs leave the nest to live on their own.

  • Foraging Skills: Hone their nighttime hunting skills.

  • Territory: Begin to establish and defend a home range, which can be about 10–50 acres depending on habitat.

🦔 4. Adulthood (6 months – 3–7 years)

  • Lifespan:

    • In the wild: Typically 3–7 years, though some can live longer.

    • In captivity: Up to 10 years.

  • Behavior:

    • Mostly nocturnal, active at night.

    • Solitary except during mating season.

    • Use a variety of grunts, snuffles, and hisses for communication.

  • Defense: Roll into a tight ball, raising their spines to deter predators.

  • Diet: Mainly eat insects, worms, slugs, snails, but also fruit, eggs, and small vertebrates.

❄️ 5. Hibernation

  • In colder climates, hedgehogs hibernate during winter (usually from late October to March).

  • They lower their body temperature and metabolism to survive months without food.

  • Build nests from leaves and grass to stay warm during hibernation.

🌳 Habitat and Range

  • Found in:

    • Woodlands

    • Grasslands

    • Gardens and parks

    • Farmlands

  • Prefer areas with plenty of cover, such as bushes, hedges, and leaf litter.

⚠️ Threats and Challenges

  • Habitat loss: Urban development reduces nesting and foraging sites.

  • Road accidents: Many are killed crossing roads at night.

  • Predators: Foxes, badgers, and dogs.

  • Pesticides: Reduce the number of insects and can poison hedgehogs.

  • Climate change: Alters hibernation patterns.

🧠 Fun Facts

  • Hedgehogs can have up to 7,000 spines on their back.

  • They are surprisingly good swimmers and climbers.

  • Use self-anointing behavior: when encountering new smells, they produce frothy saliva and spread it on their spines.

  • Hedgehogs have a strong sense of smell and hearing but poor eyesight.
