Reminder if you have an outdoor cat that you feed in your house, you are subsidizing it killing birds. Outdoor cats who are fed at home don't usually eat the birds they catch since they have a more reliable source of food at home, so they kill almost as many birds as a feral cat with no other food source but don't eat any of them and just leave them to die once they they're not fun to chase anymore. So outdoor cats killing birds is not "nature," they're an invasive species being fed farm-raised invasive species by the most widespread invasive species of all so they can go out and kill native birds that they won't eat.
