Article Correctness Is Author's Responsibility: Keeping cats indoors could blunt adverse effects to wildlife

(North Carolina State University) A new study shows that hunting by house cats can have big effects on local animal populations because they kill more prey, in a given area, than similar-sized wild predators. This effect is mostly concentrated relatively close to a pet cat's home, since most of their movement was a 100-meter radius of their homes, usually encompassing a few of their neighborhood's yards on either side.
