Again, as I said in the comment I replied to a few minutes ago, those are not naturally occurring situations, those are situations created by man.
Rats didn't swim to easter island and cats were introduced in some regions by humans, too - not to mention that the latter are a species created by humans.
Look folks, it's quite simple: species don't anihilate each other just like that, because it would disrupt the whole ecosystem around them. This isn't rocket science and even farmers (no disrespect meant, it's just that farmers are not biologists, just as biologists wouldn't know how to grow corn) know what happens when some animal species gets wiped out from a region. The effects can be invisible or can be catastrophic. And Nature doesn't "let" such things happen just like that. The whole system is "built" on a very delicate balance.
Enough babling, I think I made my point.
