While I must admire a man such as yourself, I still won't back down. Yes, I was factually incorrect on some parts, still cats pose are a huge ecological catastrophe. Nor was I incorrect on the part of violent nature of cats.
Especially free-range cats are a huge problem and contribute to many unnecessary harms to small mammals, birds, lizards etc. Over just a couple hundred years the rabid outbreak of cat populations have made animals extinct. In some cases only one cat was enough, which speaks volume on how dangerous things cats are. Keeping a outdoor cat is basically the same as you throwing your cars waste oil to a nearby stream.
They are rabid breeders and humans voluntarily helping the populations will just help these populations to grow. We should immediately take control of this problem, maybe even outlaw cat ownership all together. My words may seem weird now, but eventually we will meet some unforeseen breaking point, where the cat populations start causing huge cascade effects. If nothing else we need to limit the cat population to reasonable levels but I don't really know if that is possible.
Pic related, it's the bird species that only one cat was able to extinguish.
