Hedgehog Stock Image

Hedgehogs are primarily nocturnal, though some species can also be active during the day. Hedgehogs sleep for a large portion of the day under bushes, grasses, rocks, or most commonly in dens dug in the ground, with varying habits among the species. All wild hedgehogs can hibernate, though not all do, depending on temperature, species, and abundance of food. Hedgehogs are fairly vocal and communicate through a combination of grunts, snuffles and/or squeals, depending on species.
