Hedgehog Cage Size Calculator
Calculate the minimum and recommended cage size for one or more pet hedgehogs based on number of animals and activity needs.
Hedgehog Housing Requirements
African pygmy hedgehogs (Atelerix albiventris) are the most common pet hedgehog species. They are active, solitary animals that need considerably more space than many people expect.
Minimum vs. Recommended Space
| Standard | Floor Area | Notes |
|---|---|---|
| Minimum (welfare baseline) | 0.7 m² (7,500 cm²) | About 2 ft × 4 ft |
| Recommended | 1.0 m² or more | 60 cm × 180 cm (2 ft × 6 ft) |
| Ideal (with wheel + enrichment) | 1.2 m²+ | Allows a running wheel, hides, and foraging space |
In imperial terms, the minimum is approximately 24 inches × 48 inches (2 ft × 4 ft).
Why Hedgehogs Need So Much Space
Hedgehogs are crepuscular to nocturnal and can run 3–8 km (2–5 miles) per night in the wild. A running wheel is essential — without it, hedgehogs become obese and develop Wobbly Hedgehog Syndrome (a degenerative neurological condition) more easily. The wheel alone requires at minimum a 30 cm (12 in) diameter solid-surface wheel, which takes up significant floor space.
What Goes in the Cage
| Item | Minimum Size |
|---|---|
| Running wheel | 28–30 cm (11–12 in) diameter, solid surface |
| Hide / sleeping house | Large enough for hedgehog to fully enter and turn around |
| Litter area | 20×20 cm (8×8 in) corner |
| Food and water dishes | Low-sided, stable base |
Cage Style
- C&C grids — Popular DIY option, inexpensive, very customizable
- Large plastic bin cages — Budget-friendly, retains heat well
- Wire-bottom cages — Avoid these; hedgehog feet and legs can get caught
Solitary Nature
Hedgehogs are solitary and should generally be housed one per cage. Two females may co-exist only if raised together, but should be monitored closely for fighting. Two males should never be housed together.
Temperature Requirements
Hedgehogs require ambient temperatures of 22–26°C (72–80°F). Below 18°C (65°F) they may attempt to hibernate, which is dangerous and potentially fatal in captivity.
