Hedgehog Lifespan
Hedgehogs face many challenges. The first 4 weeks of a hedgehogs life are likely to be its last, with 1 out of 5 hedgehogs dying in this time. Their lifespan depends a lot on weather; dry or cold summers will make life much harder for hibernation. The average hedgehog will die at about 3 years old. 1 in 1,000 hedgehogs may live to be 10, but it is very doubtful that a hedgehog will live to be older than this, if only that its teeth get worn down and he starves.
Hedgehog Death
One of the largest causes of death in the hedgehog in hibernation. It is very risky: hedgehogs of defenceless against cold, floods and nest destruction. All the time they are burning up their fat reserves. Predation is not a threat to the hedgehog: they are very well protected by their spines and roll up mechanism. Gamekeepers often kill hedgehogs, because hedgehogs eat their bird's eggs. Motor cars are also a threat to the hedgehog. However, the primary cause of death to the hedgehog is simply hibernation
