Another anecdote - my cat was 100% indoor first 6-8 month I had him. Then I started to let him outside during day and he started immediately to try to hunt. His first attempts were hilarious, like trying to hide just by laying down and flap around with his tail from excitement, birds would look funny at him and just casually jump away if he got too close. He also wore a bell all of the time, which made it even more impossible. But after half a year he started to consistently kill 1-3 animals per season, birds and mice. One time he killed a huge pigeon. And thats only the kills I know of, since he brought them back home to show off. Not saying that can account for billions, but thats just one cat who had everything against him and also was well fed at home.
