Cats who kill for fun and cats who kill for food would select completely different birds. And the cats would need a predator too if you want survival of the fittest. These house cats are getting energy on the side- that's not Darwin. That's like saying "Give the cheetah steriods and see if the gazelles can out run him then!" You know what I mean? A cat who has tiny birds and mice as their sole energy source will be much slower and catch way less prey than the ones who go home and get to eat 500kcal of food.
