Cats Responsible For Driving Many Species To Extinction

Invasive predators major cause of species extinctions
Introduced rodents, such as black rats and house mice, have the most widespread impacts of invasive predators worldwide, linked to the extinction of 75 species, including 52 birds, 21 mammals, and two reptiles.
Feral cats aren’t far behind, coming a close second, contributing to 63 extinctions.
On some islands, rats do slightly more damage than cats. On large continents like North America however, where native predators like hawks, foxes and Great Horned Owls prevent invasive species of rats from spreading into wilderness areas, cats do far more damage to native songbird populations, especially because unlike rats they are sustained and protected by their human owners.
I saw a Cooper's Hawk take a Norway rat in a large local park not too long ago. Rats are just the right size to make for a good meal for a Great Horned Owl, a Cooper's or Red-tailed Hawk or a Coyote, and probably easier to catch than native rodents which have adapted to these native predators during many thousands of years of evolution.
