They are only a meaningful problem where no native feline species are present. Asia, Africa and Europe (excluding islands) have native wild cats. House cats are a direct descendant of the African wild cat and have been domesticated and spread since ancient times. They can be a danger to the "genetic distinctiveness" of wild cats in some places. But they mostly are not the same level of danger to native species like they are in America and Australia.

I am aware and the damage they can do is legit, but people seem to automatically assume everyone lives in such place and i have been burned before.

As far as i am aware the concept of the family cat being a wild/stray that decides to just live at your house is an ancient dynamic here.

I once found a cat in need and took it to a vet where they found it had a chip. Returned it to the official owner, they already considered it the neighbors cat more than theirs and those neighbors hadn’t seen it for 3 months. They assumed it found some better place like rich lonely elders.

I assume you'll concede absolutely nothing to the "what about cats who roam free but come back of their own free will" point, as you don't think cats count because they're cruel invasive bird massacring demon monsters?
