You may be an extensive reader but, apparently your perceptions of the value of a natural system is flawed. Most native species have a function wether perceived or unperceived. The introduction of a non-native serves merely to destroy balance. Although the balance of natural systems have already been radically altered, they do not need any additional help from people who refuse to keep their pets under control.

Is there a place in this country where people live and where the domestic American cat is a non-native? Seems like I see cats every where I go.

1m years ago finches didn't exist on the Galapagos Islands. At some point the "non-native" species was introduced, not by man I might add. At what point does a non-native species become native?

I never said that people shouldn't keep their pets under control. I merely stated that no one -no one should be shooting a cat for doing what Cats do. I will agree that the natural balance is off in a great many ways, but killing an animal that is doing 'animal things' does not entitle anyone to kill said animal. And once upon a time neither dogs nor cats were 'domesticated' if you have a problem with this, I strongly suggest you build a time machine go backwards and beat the stuffing out of the first 'people' who domesticated them. Enough said on this subject.
