Trollnøste
Region of origin: Norway
Literally “demon-yarnball” and alternatively known as troll-balls and troll-cats, the trollnøste are witches’ familiars made from hair, wood shavings, farm scraps and blood and given life by invoking a pact with Satan. The trollnøste would sneak onto farms at night, stealing milk from cows and cream from inside the household and return them to their witch’s pails. In some versions, the witches are sympathetically linked to their troll-cats, and harming the latter will also harm the former, and burning any residual cream the creature might spill or leave behind will cause pain in the witch who owns it.
