The Jarvey is found in Britain, Ireland and North America. It resembles an overgrown ferret in the most respects, expect for the fact that it can talk. True conversation, however, is beyond the wit of the Jarvey, which tends to confine itself to short (and often rude ) phrases in an almost constant stream. Jarveys live mostly below ground, where they pursue gnomes, though they will also eat moles, rats and voles .
