If indeed is not do for food then I should think something should be done perhaps, although is not clear what to do. Other people know better and wrote some comments. Another comment says "cat owners should certainly be fined for allowing their cats outdoors on continents where cats are non-native"; perhaps in such continents, force to go inside if they killed too many birds (and if you don't want inside of your home, then it will be the cats jail, I suppose; or else, in the other continent, perhaps). Although, actually I don't really know, especially, since I have not observed it by myself and I have not counted.
