Hedgehogs: senior care and slowing down

Quick answer

Hedgehogs do not have a sport or working career to retire from. What they do have is a short life and a noticeable slowing down in the last stretch of it.

Senior care for an African pygmy hedgehog is mostly about three things: keeping the animal warm, keeping it moving without hurting it, and catching the illnesses that become common with age.

• The single most important change is not a supplement. It is stable warmth.
• Do not remove the wheel because the hedgehog has slowed. Adapt it.
• Weight loss in an older hedgehog is a red flag, even when appetite looks fine.
• Weigh regularly, and write the numbers down.
• Sight and hearing fade, so approach and handling need to change.

A senior hedgehog spends more of the night settled and less of it running. The aim is to keep the running that remains comfortable and possible.

Decide in 60 seconds

Why ageing hits this species the way it does

An African pygmy hedgehog is small, tropical in origin, and metabolically fast. All three shorten the runway.

Small tropical mammals lose body heat quickly, and an older animal with less muscle and less fat regulates temperature less well. That is why room warmth becomes more critical, not less, as a hedgehog ages.

Activity is the second pressure. A hedgehog evolved to cover long distances foraging each night. When arthritis, footpad problems or simple stiffness cut that distance, calorie needs drop but the food bowl usually does not change.

Obesity then feeds back into the mobility problem. A heavier hedgehog runs less, and one that cannot ball up fully has lost its main defence and is harder to examine.

The third pressure is disease. Dental disease and tumours are both frequently seen in older hedgehogs, and both are easy to miss in an animal that hides discomfort well and is often only seen at night.

Adapting the setup

Non-slip flooring, a low-entry bed and everything reachable without climbing. Most senior adaptations are about removing height and improving grip.

Keep the wheel, change the wheel.

A solid running surface with a shallow entry lip lets a stiff hedgehog get on and off. If the wheel has become hard to turn, a stiff bearing may be the reason activity dropped, not the hedgehog.

Never remove the wheel because the hedgehog runs less. Some running is far better than none, and inactivity accelerates weight gain.

Take out the height.

Remove ramps, upper levels and anything requiring a climb. Older hedgehogs fall more, and a fall onto a hard cage base causes real injury.

Improve grip.

Fleece liners or non-slip matting give better purchase than a smooth base or loose bedding for a hedgehog with weaker legs.

Bring everything closer.

Food, water and the sleeping area should all be reachable in a short, flat walk. A senior hedgehog that has to cross the cage for water may simply drink less.

Warmth is the priority.

Keep the room warm and stable, and verify it with a thermometer rather than judging by feel. Avoid draughts and never move an older hedgehog to a cooler room.

What to check every week

Feet, nails and gait are where mobility problems show first. Overgrown nails alone can stop a hedgehog using its wheel.

Weigh on the same scale, on the same day of the week, and record it. A trend across a month tells you far more than a single reading.

Look at the nails. They keep growing, and an older hedgehog that runs less wears them down less. Overgrown nails curl, catch, and make walking painful.

Check the feet and legs for swelling, sores, or a reluctance to bear weight.

Watch the gait for a few seconds while the hedgehog walks. Note any drag, stumble, or lean to one side.

Look at the eyes for cloudiness, discharge, or an eye held closed. Eye injuries and eye disease are common and need prompt attention.

Watch it eat. Dropping food, chewing on one side, or turning away from harder items suggests mouth pain.

The senior routine

What never to do

Do not cut food back sharply because the hedgehog has gained weight. Rapid weight loss is dangerous in this species, and portion changes should be made gradually with veterinary input.

Do not add supplements, joint products or human painkillers on your own. Several human medicines are toxic to small mammals, and dosing a hedgehog by guesswork is unsafe.

Do not bathe an older hedgehog often, or leave it damp. Chilling after a bath is a real risk at this age.

Do not accept wobbling as ordinary ageing. Unsteadiness has specific causes worth investigating, and some are treatable.

Do not house a senior hedgehog with another hedgehog for company. This species is solitary at every age, and pairing causes fighting and injury.

Warm, low, dark and reachable. That combination covers most of what a senior hedgehog needs from its enclosure.

When to get help

Book an exotics or small mammal vet the same week for weight loss, a new lump, a change in how the hedgehog eats, a limp, or a clear drop in wheel use with no mechanical cause.

Go the same day for a hedgehog that is cold and sluggish, unsteady on its feet, breathing with effort, or has an eye that is closed, cloudy or weeping.

Bring the weight record, the room temperature readings, the current diet and portion, and a short video of the hedgehog walking. A video of the gait is often more useful than an examination of an animal that balls up on the table.
