What is the Hedgehog Lifespan Estimator?
The Hedgehog Lifespan Estimator predicts expected lifespan range for hedgehogs based on breed and size. Knowing where your hedgehog sits on that curve helps you time vet checkups, adjust diet, and watch for age-related changes before they become serious.
Hedgehogs generally live 4-6 years when they are well looked after. As an insectivore, what a hedgehog needs from its diet changes across its life stages. African pygmy hedgehogs need a solid-floor enclosure kept at a steady 24-27C. Below that they may attempt hibernation, which is dangerous for them. They are solitary and must be housed alone. Health problems that show up most often in hedgehogs include wobbly hedgehog syndrome, attempted hibernation from cold, obesity, which is part of why tracking this over time pays off.

How does the Hedgehog Lifespan Estimator work?
The calculation is based on species-specific aging curves rather than a flat multiplier, most animals age fastest in their first two years and then more gradually, and larger individuals within a species tend to age faster in their senior years than smaller ones. It is a starting point, not a verdict. Somebody who has actually examined your hedgehog will always know more than a formula does.
What changes the answer
- Size or breed variant: since larger animals within the same species often age faster later in life
- Overall health and any chronic conditions, which can accelerate the effective aging rate
- Genetics and lineage: which set the baseline lifespan range
- Care quality: diet, exercise and preventive vet care all influence how a hedgehog ages
How do you use the Hedgehog Lifespan Estimator?
- Answer "How is the animal kept?"
- Pick your body condition (Underweight, Ideal weight, Overweight, ...)
- Pick your preventive veterinary care (Routine annual checks, Only when unwell, Rarely or never)
- Answer "Neutered or spayed?"
- Pick your breeding background (Mixed or unknown, Pedigree from health-tested lines, Pedigree, no health testing)
- Press Calculate, then read the result alongside the sources listed below
If two people care for your hedgehog, agree on one method and stick to it. Half of all confusing results come from measuring differently each time.

Before you rely on this
Averages hide a lot of variation. The figure here reflects what is typical for hedgehogs, but your hedgehog may sit well outside it for perfectly ordinary reasons. Use the result to spot changes over time in your own animal rather than to compare it against other people's pets.
