> If Google has chipped the cats as they say in the article, then an RFID reading station in the owl territory would allow them to identify and eliminate those cats predating on the owls I expect.
That's a good idea. But still probably unacceptable to cat lovers. Maybe there are middle options. Google could build a very large cage, and release non-adopted cats there. Or if that's not feasible, it could declaw and/or defang them. And yes, I know that those are horrible things to do to cats (or anyone, for that matter). But maybe it's better than death.
