Quolls, the size of a small cat, are carnivorous marsupials native to Australia and New Guinea.
They are mainly nocturnal and mainly solitary.
All (6 species) are threatened by imported foxes and cats, which compete for food as well as prey on quolls,
and by habitat loss. Some, mainly the Tiger Quoll in Queensland, are also at risk of poisoning by imported, toxic marine toads.
The Eastern Quoll can be brown or black, both with white spots. It has been exterminated from the wild in mainland Australia,
mainly by predation and habitat loss, but remains in Tasmania.
Like other Quoll species, they are solitary and remain in burrows in the day, meeting at night to mate
or to use the communal quoll latrines some distance from their burrows.
