| | Non-Native Species A Brief Account |
 | | The Norway Rat is the largest of the four, is rather more large-bodied than the Black Rat, which has a longer tail and is a more agile climber. |
| | Both measure about 40cm from head to tail, in contrast to the smaller House Mouse, which is only about a quarter to half the size; the Polynesian Rat is slightly larger but still is the smallest Rattus species, its native home in the humid tropical regions of South-east Asia. |
| | These venturing omnivores seldom shun potential food sources, and consume almost anything from grains, vegetables, meat, milk, confectionary, soap, milk, eggs, or less nutritious structures such as sofas and wood to grind of the tips of their ever-growing incisors, adapted originally for the consumption of plant stems and other vegetable materials. |
