Yeah the comment you replied to is hyperbolic for sure, but even as a cat person I can see where they’re coming from. At the very least a lot of cat owners have a hard time recognizing the (iirc, scientifically proven) fact that the average outdoors cat kills a lot more small wildlife than they would ever require to survive, and by these numbers, it doesn’t take a ton of them to have a noticeable impact on an ecosystem, especially if you take into account the fact that they usually easily outnumber their natural predators since they are such a popular pet.
