When foreign animals are introduced and there are no natural predators the balance is destroyed with severe results:-http://blogs.scientificamerican.com/extinction-countdown/feral-cats-numbat/?WT.mc_id=SA_DD_20151216-"Feral cats have scratched up another victim. Earlier this month the Western Australia (WA) government listed a rare marsupial called the numbat, also known as the banded anteater (Myrmecobius fasciatus), as endangered. The colorful squirrel-like critters—literally the emblem of Western Australia—only grow to about 45 centimeters in length and have no defense against hungry felines.-***-"Despite their risks, numbats are doing better than some other species. The same day the numbat was declared endangered four other long-lost mammals were finally identified as extinct: the desert bettong (Bettongia ogilbyi penicillata), inland burrowing bettong (Bettongia lesueur graii), south-western rufous hare-wallaby ( Lagorchestes hirsutus hirsutus) and Gould's mouse (Pseudomys gouldii). All were probably wiped out by invasive predators like foxes, cats, mice or rats. None of them have been seen for at least 50 to 100 years."-Comment: A natural balance of nature never lets this happen. The balance is very important for the ladder of predation is maintained.
