Hedgehog Gestation Calculator

Hedgehogs are pregnant for approximately 35 days on average, with a normal range of 34–37 days. This is fairly consistent across common pet species like the African Pygmy hedgehog.

Add 35 days to the breeding date. Use the calculator above for an exact expected due date and the full 34–37 day normal range.

Litters typically range from 3 to 5 hoglets, though litters of 1–2 or as many as 6–7 do occur. First-time mothers often have smaller litters.

Signs include visible weight gain and a rounder body shape in the final two weeks, nest-building behavior, and increased appetite. Pregnant hedgehogs also often become more reclusive and less tolerant of handling as the due date approaches.

Hoglets are born blind, with soft white spines that harden within hours. Avoid handling the nest for at least the first week — female hedgehogs are notably prone to abandoning or cannibalizing a litter if stressed or disturbed too soon after birth. Eyes open around day 14, and weaning occurs around 4–6 weeks.

In climates or captive setups where hedgehogs experience temperature drops, an entry into torpor or hibernation-like states can suppress breeding cycles and, if it occurs during pregnancy, seriously endanger the litter. Pet hedgehogs should be kept at a stable, warm temperature (75–80°F) throughout breeding and pregnancy to prevent this.
