I’ve seen a lot of stats about cats and it seems very likely they have important conservation implications in island ecosystems where birds did not evolve with similar predators.
But I’ve not seen evidence of conservation impacts on the mainland where we do and did have similar predators in the past. Just stating that cats eat a lot of birds doesn’t mean they’re a threat to overall populations.
Again it would depend on where those are—threatened species are disproportionately located on those islands I mentioned. Furthermore it doesn’t assign any causation to cat predation.
Maybe cats are a serious conservation threat on continental areas but I’m just saying I haven’t seen evidence of this.
Here’s a study from Oklahoma State University specifically talking about the effects of mainland cats in contrast to island cats:
“Our review shows overwhelming evidence that, beyond causing island extinctions, where there were no native predators, and massive numbers of mainland wildlife deaths, cats can exert multiple types of harmful impacts on mainland wildlife species that are reflected at the population level,”
Thanks, this seems more in line with what I was wondering. But I’ll need to see if I can get access to the full paper. The example given in Australia actually fits my hypothesis since they historically lacked felid predators. So I’d like to see the full list to see the location and severity of the effects they’re reporting.

True, but that article says that over 350 of their prey species are at risk species, and that several of those are suspected to already be extinct.
I love cats—I think most people should have them—just be responsible with your furry murderers.

Oh I’ve got the link, but it’s paywalled. I’ll find the full paper later.
