The Teakettler (Urocyon iugulebesonia) is a legendary creature from American folklore with origins in lumberjack culture, specifically the lumber camps of Minnesota and Wisconsin. It is part of a group of similar folklore creatures known collectively as Fearsome Critters. Overall, it resembles a small stubby legged dog with the ears of a cat. It gets its name from the sound it makes, which is akin to that of a boiling tea kettle. It only walks backwards (by choice) and steam issues from its mouth as it makes its whistle. Only a few lumberjacks have seen one, as they are very shy, but if a boiling kettle is heard and nowhere to be found, it is sure that a Teakettler is nearby.
An account is given by Jorge Luis Borges under "Fauna of the United States" in Book of Imaginary Beings (1957).
