How old do hedgehogs live?

There are significant differences here. As a rule, hedgehogs live in the wild between 2 and 3 years. In some cases, very old specimens are reported. These are said to be up to 7 years old.

How old does the hedgehog live in nature?

As is the case with other animals, the living conditions affect the age of the hedgehog. If you ask yourself how old the hedgehog will become, then you should not disregard the genetic conditions. In many cases, however, luck plays a decisive role when it comes to how old a hedgehog will live in the wild.

If the hedgehog does not fall victim to a larger predator, such as the fox or the marten, it is often driven to death. Not unimportant for the age of the hedgehog is also the displacement by humans. The hedgehog finds fewer and fewer places to retreat to in gardens and parks, as everything is becoming bare and modern. Last but not least, agriculture is also significantly involved in the age of hedgehogs. The mammals have to struggle with chemical fertilizers or snail poison, which usually ends in death for them.

Basically, it borders on a miracle when a hedgehog lives to be 2 or 3 years old in nature. In many cases it is a miracle if the small mammals survive the first year of life.

The rapid maturation process of the small mammals makes up for some of the life expectancy here. Hedgehogs are able to reproduce after only a few months, so it can be said that they are adults at the age of 1 year. This is one of the reasons why the population of hedgehogs in Germany has remained stable so far.

How old does the hedgehog live in captivity?

As pets, hedgehogs have a very good chance of living a fairly long life. Food is permanently available to them and no exhausting hibernation has to be kept. Here the care decides on the duration of a hedgehog's life.

However, keeping them as pets is not an option. In nature, the hedgehog often covers many kilometers in search of food. In captivity, he is taken out of the enclosure for a cuddle and otherwise just sits in his cage. The hedgehog can become overweight so quickly and, as with humans, this reduces life expectancy. There are the rare cases here that a hedgehog lived to be 10 years old.

The enemies of the hedgehog in nature

How old a hedgehog becomes depends very much on the enemies it encounters in nature. The most dangerous are badgers and eagle owls. Further enemies are:

  • Fox
  • Lynx
  • Marten
  • Polecat
  • Dogs
  • Hawks

Surely the Hedgehog curl up in case of danger and enemies can not harm him. However, some of the enemies have specialized in hedgehog hunting. This is a very important reason, if you ask yourself the question, how old does a hedgehog.

Age of hedgehogs in human years

For you it may sound very low when you are told that a hedgehog can live between 2 and 7 years. But for a hedgehog this is very long. The following table shows you clearly what the hedgehog age means in human years.

How can you determine the age of the hedgehog?

You can determine how old a hedgehog is by the following characteristics.

Garden animal - A life with nature

Welcome to my animal blog! My name is Dirk and I am happy to take you on my journey through the fascinating world of animals and gardening.

Born 54 years ago, I have had an insatiable curiosity for the animal world around me since childhood. Although I have moved professionally in other industries, my true passion has always been animals and nature. It is remarkable how a small garden has become such an important part of my life.

Many of my fondest memories are associated with the animals that share our home. Whether it's the curious squirrels that scurry across the trees in the morning, the colorful variety of birds that visit our feeders, or the busy bees and butterflies that pollinate our flowers, every moment with them is invaluable to me.

This blog is my contribution to share my experiences, discoveries and insights with like-minded people. Here I will share stories of unforgettable encounters with animals, give tips on gardening and creating wildlife-friendly habitats, and take you on my journeys through nature.

Thank you so much for being here!
