A few weeks ago I heard the claim that you have to supervise your cat while it is outdoors or else you will be responsible for extinction of certain species... That sounded a bit ridiculous to me so I read a few articles on that topic. (the first few sources of https://en.wikipedia.org/wiki/Cat_predation_on_wildlife https://en.wikipedia.org/wiki/Cat_predation_on_wildlife are a good start) While cats do kill a lot animals, including endangered species, many articles that claim your outdoor cat is irreversible destroying wildlife seem quite sensationalist. Many articles make it sound like pets are the real threat but only mention on the side that feral cats are responsible for the majority of killed animals instead. It would be far more beneficial (for wildlife, pets and feral cats) if people would support projects for controlling feral cat population than confining their pets.
