Darcy The Cute Hedgehog

Hedgehogs occasionally perform a ritual called anointing. When the animal encounters a new scent, it will lick and bite the source, then form a scented froth in its mouth and paste it on its spines with its tongue. It is unknown what the specific purpose of this ritual is, but some experts believe anointing camouflages the hedgehog with the new scent of the area and provides a possible poison or source of infection to predators poked by their spines. Anointing is sometimes also called anting because of a similar behavior in birds.
Similar to opossums, mice, and moles, hedgehogs have some natural immunity against snake venom due to the protein erinacin in the animal's muscular system.
In captivity, hedgehogs tend to get along with dogs, cats and other pets. On the rare occasions when they do feel threatened by these animals, the hedgehog will roll into a ball until the threatening animal disappears. Still, care should be taken to protect hedgehogs from particularly large, aggressive, or mischievous pets.
