A rat that eats other rats?
The Kowari lives in the dry grasslands and deserts of Australia. They dig holes to hide in during the afternoon as they are a nocturnal animal. Although the Kowari looks similar to a squirrel or rat, it is an entirely different animal. In fact, the carnivorous Kowari feeds on rats. They use their fore legs to subdue their prey, which includes lizards, birds, and rats, and use their sharp teeth to make the final kill.

Declining numbers due to grazing by domesticated animals.
Domesticated animals put out to pasture are causing problems for the Kowari. It is not the food that is at stake, as domesticated cattle and sheep only eat grass. Rather, the problem is how the grazing changes the Kowari's habitat, which causes their number to decline. Their habitats are disappearing with the construction of roads and towns, putting the Kowari in even greater danger of extinction.
