I'm sure you'd prefer I didn't reply, because I can and will soundly refute your claims.  And you don't ignore hate, just reality.

Current population of resident bird species is estimated at 10 billion, with a yearly doubling of that number during peak migration seasons (US F&W).  Free-roaming cats ALONE take down 1/3 of the resident bird population (and anybody's guess as to how many migrants) on an annual basis.  This is unsustainable.

And here are the sources for the numbers you failed to successfully dispute:
