>kill billions of native birds every year. what is wrong with killing billions of ill and old birds? That is how Nature works, and the other predators do it in the non-developed areas where humans didn't push out those predators from. In the developed areas the other predators are gone, so thanks to the cats who do the necessary job of all those missing predators. >They're an invasive species in most states Do you see many native predators around humans? If anything the humans is the invasive species doing pretty much all the damage.
