I don't know the specific numbers, and I've only just seen one or two studies (would appreciate an alternative numbers) - but if a three 3 billion bird reduction is almost a third of the total population in birds in North America since 1970s, and cats are killing at least 1.3 billion per year... I guess that's "fine for the most part"? https://www.science.org/doi/10.1126/science.aaw1313 https://www.science.org/doi/10.1126/science.aaw1313 The predation of cats is also unnaturally controlled as they are domesticated; people view them as pets primarily and thus prevent them from being killed (their predators are also heavily controlled - wolves, coyotes, etc). I don't see how you could compare that niche to previously extinct, naturally local species.
