Quoll

Quolls (genus Dasyurus) are carnivorous marsupials native to Australia and Papua New Guinea. There are six species of quoll, four in Australia and two in New Guinea. 
The name "dasyurus" means "hairy tail". Adults are between 25 and 75 cm long, with hairy tails about 20-35 cm long (about the size of a cat). Like all marsupials, females have a pouch to carry their babies.
Quolls are threatened by eating toxic cane toads, but a University of Sydney project is teaching them not to eat them.
The family Dasyurini to which quolls belong also includes the Tasmanian devil, antechinuses, the kowari, and mulgaras.
