Oh shit no, we have so many cat colonies with booming feral populations as it is all over the place. Which is part of the absurdity. My cat will likely kill nothing while going outside to lay in the sun and go pee, while there’s hundreds of outdoor ferals fed daily by volunteers, because the community has decided to be humane and not mass euthanize, only mass spay and neutering when they can be rounded up. The main threat to our native birds are mosquitoes (edit:), which is mostly in the deep uninhabited valleys where people and cats don’t go anyway.
