I think the point that most people miss is that these studies mix together domestic and unowned/ feral cats. It is highly likely that our domestic cats who are fed well don't hunt as much

I find at least 5 dead birds every year. I have blink camera videos of the local cats stalking the birds.

More than anything else, it's inconsiderate to your neighbors who might not want your cats on their property. My wife and I take great joy in watching the local doves nest and raise chicks, and we will absolutely defend them from feral pests and outdoor "pets" alike.

Around me they mostly kill mice, chipmunks and baby squirrels.
