A vole is a small rodent resembling a mouse but with a stouter body and a shorter, hairier tail and a slightly rounder head. The Owlery floor is covered in regurgitated skeletons of these creatures, indicating that they are a favourite food of owls. An old lady near Knockturn Alley warned Harry Potter in 1992 not to go from Diagon Alley to Knockturn Alley, and threatened him with turning him into a vole. Jarveys are known to eat these.
