This is not a quoll but it is a dasyuromorph. It is a red-tailed phascogale, a mouse-sized marsupial from the Wheatbelt region of Western Australia with a long bushy tail.

There are two kinds of phascogales, the red-tailed phascogale and the brush-tailed phascogale. Like many species of small carnivorous marsupials, when male phascogales come into season they go into a frenzy of non-stop mating which leads to their eventual death by exhaustion as their immune system shuts down. Female phascogales may survive as many as three mating seasons.
