# Hedgehog temperature & cage checker

> Enter your room temperature and cage floor area to see whether your hedgehog is safe. African pygmy hedgehogs need 70–85 °F (21–29 °C); going cold triggers a hibernation attempt that is usually fatal, and going above 90 °F (32 °C) risks heat stroke. Cage floor area should be at least 2 × 3 ft (61 × 91 cm).

## What temperature does a hedgehog need?

African pygmy hedgehogs need 70–85 °F (21–29 °C). Below 65 °F (18 °C) they attempt hibernation, which is almost always fatal; above 90 °F (32 °C) they risk heat stroke. Cage floor area should be at least 2 × 3 ft (61 × 91 cm) — bigger is better because hedgehogs run several miles a night in the wild.

## Limits at a glance

| Limit | Value | Why |
|---|---|---|
| Ideal temperature | 70–84 °F (21–29 °C) | Stable range where hedgehogs stay active and eat normally |
| Heat-stroke threshold | > 90 °F (> 32 °C) | Panting, splayed-out posture; cooling the room is urgent |
| Cage floor minimum | 2 × 3 ft (61 × 91 cm) | Larger is better — hedgehogs run several miles a night |
| Heating options | CHE, heat mat | CHE preferred — no visible light to disrupt nocturnal rhythm |

Pair the room temperature with a thermostat-controlled CHE or heat mat. A probe thermometer inside the cage is essential — ambient thermometers miss micro-climates.

## Where the limits come from

Hedgehogs cannot regulate their body temperature the way mammals from temperate climates do. When their environment drops below about 70 °F (21 °C) they start to slow down and may enter a torpor state that looks like hibernation. Pet hedgehogs are not physiologically prepared for it — most that attempt it die.

Above 85 °F (29 °C) the hedgehog pants, splays out flat, and looks for a cool surface. Above 90 °F (32 °C) the risk of heat stroke becomes serious. Use a ceramic heat emitter (CHE) on a thermostat to warm the cage in winter; in summer, keep the room at or below 85 °F (29 °C) with air conditioning or a fan — a CHE can only heat, never cool.

Floor area matters because hedgehogs run several miles a night foraging in the wild. The 2 × 3 ft (61 × 91 cm) minimum is welfare-driven; many keepers provide enclosures of 3 × 4 ft (90 × 120 cm) or larger with solid floors (no wire), bedding for digging, and a hidden nest box.

Worked example: a room at 75 °F with a 36 × 48 in cage is comfortable as is.

Cold-room warning: at 65 °F the result is too cold (hibernation attempt risk) — URGENT: 65 °F (18 °C) is below the 70 °F (21 °C) floor — hedgehogs that get too cold attempt hibernation, which is usually fatal.

Heat-stroke warning: at 90 °F the result is at heat-stroke risk.

Small-cage warning: a 20 × 24 in cage is below the minimum — the 2 × 3 ft (24 × 36 in) minimum floor area.

## Hedgehog setup questions, answered

**Q: What temperature is too cold for a hedgehog?**

Anything below 70 °F (21 °C) puts a hedgehog at risk. Below 65 °F (18 °C) the hedgehog is likely attempting hibernation, which is usually fatal — get it to a hedgehog-savvy vet immediately if you see wobbling, cold belly, or inability to uncurl.

**Q: What temperature is too hot for a hedgehog?**

Above 85 °F (29 °C) the hedgehog is heat-stressed; above 90 °F (32 °C) the risk of heat stroke becomes serious. Provide a ceramic tile for them to lie on and move the cage to the coolest room.

**Q: How big should a hedgehog cage be?**

At least 2 × 3 ft (61 × 91 cm) of floor area. Most hedgehogs do best in cages that are 3 × 4 ft (90 × 120 cm) or larger, with solid floors (no wire — wire floors injure feet) and a nest box for daytime sleeping.

**Q: Do hedgehogs need a heat lamp or heat mat?**

In most homes a ceramic heat emitter (CHE) on a thermostat is the safest option — it heats the air without producing visible light, which can disrupt their nocturnal rhythm. A heat mat under one corner also works as a backup.

**Q: Can I keep my hedgehog in an outdoor shed?**

No. Outdoor temperatures swing too much and hedgehogs need a stable 70–85 °F (21–29 °C) range year-round. They also need protection from drafts and predators.
