D. hallucatus is also known for its pointed snout and relatively highly-set body, making it stand out from other species in this genera. The little northern native cat is a very aggressive carnivore . During the activity of searching for food with its moist and dripping snout, the native cat constantly emits audible sniffling sounds. This animal has a huge appetite and is never fully satisfied. The native cat has even been known to overpower a duck.
All native cats appear to be monoestrous, winter breeders.
The most successful reproduction of Dasyurus hallucatus occurs near creeklines due to the constant supply of water. At birth they measure only about 3 millimeters in length. Young are carried by the mother for eight to ten weeks and as many as one-third of them may be lost by September. The young are suckled in the nest until they are about five months old and they reach full maturity by 10 to 11 months. Reproductive seasonality occurs in this species.
