The Cardassian vole is a fictional rodent species in the series Star Trek: Deep Space Nine. It was a pest aboard the space station, infesting Quark's Bar as well as Ops where it chewed through wiring. It is quite unlike the voles of Earth, most notably in that it has six legs. It is also much bigger than a terrestrial vole.
Although he has denied it, Quark hosts vole fights. Morn has been known to assist him in setting up the events by painting numbers on the voles' backs.
