They are mostly snakes.
predator is the alligator and bigger birds, also the prey would have to be the field mice and smaller insects and mammals..
Predators of the tiny musky-rat kangaroo include dingoes, wild dogs and quolls. Quolls are carnivorous marsupials, sometimes incorrectly called "native cats".
