I tend to agree that domestic cats with owners are not really the problem (ours when I was a kid living a farm did kill some birds/snakes/rabbits, but not in large numbers). Although cats as pets might not be killing as much as their feral cousins, the impact of a bird being killed by a cat though is a bit worse than non-bird victims. The likelihood the offspring of the victim bird will not reach adulthood is near 100% versus only 50% (or less in animals that don't require parental rearing) with other animal victims[1]. The problem is more with feral cats that people dump and have no source of food other than what they catch. Combined with most of them not being spayed or neutered, the feral cat populations in many countries grows at an alarming rate as they tend to not have any natural predators. However, that has changed a bit here in the United States with the rise of the coyote populations recently and may help to stabilize the feral cat problem. [1] near 100% since most birds need both parents to raise their young (and will likely abandon the nest if one is killed) and the 50% coming from the chance the animal killed was a female non-avian species.
