The native species we have left are the ones that have adapted the best to the preaditors we introduced and the habitat changes we have made e.g. Paradise Ducks are doing fine. There are no weka on the east coast whereas there are heaps on the west coast. East coast is a far more modified environment with far more introduced preaditors.
A cat may catch a few mice but thats largely irrelevant as they can breed faster than they get eaten. It's like trying to shoot rabbits to reduce numbers. Go to a farm with heaps and shoot 1k rabbits (which I have done). Go back the next week and you won't be able to tell the difference because they are breeding so fast they have replaced the 1k that got shot. They are only limited by food sources. If you wanted to control them you would have to kill the last one i.e. blanket the place with 1080 repeatadly (which is the standard approach with high rabbit numbers).
