Elimination of cats drives trophic cascade

Published on Resilience science:

• “describes how, on Macquarie Island, an important breeding location for several species of penguin, the elimination of invasive cats in attempt to protect the penguins has triggered a trophic cascade as herbivore populations have boomed defoliating the island.
• The study’s lead author Dana Bergstrom, of the Australian Antarctic Division, estimates that nearly 40% has been modified, with 20% having moderate to severe change, and that rabbits have convert vegetation from complex communities to short, grazed lawns or bare ground.“

So that´s why cats are more than good pets, and now studies have found that cats can lower a human’s high blood pressure, boost their immune systems and recover more quickly after heart attacks. Do you need more reasons?
