> The U.S North American Bird Conservation Initiative estimates that our pet felines kill some 2.6 billion birds annually in the U.S. alone.
The 100M pet cats in US on average kill 26 birds/yr? Doesn't seem right. When I track the source[1] of research, the estimates include both "own" and "unowned" cats and rely on some assumptions like "a correction factor to account for owned cats not returning all prey to owners", amongst others.
