Okay, this an instance where I would like the downvoters to explain the downvoting. The submitter asked for "low-probability, high-impact" events. Cats destroying local ecosystems is a low-probability, high-impact event and perceived as tolerable. We've seen situations where non-native animals have messed up ecosystems, and there are a lot of cats in the world hunting lower on-the-food-chain prey. Is the word "cat" taboo on HN or something? An article on feral cats and dogs:http://www.bc.edu/schools/cas/envstudies/research/feral.html http://www.bc.edu/schools/cas/envstudies/research/feral.html Sigh Nobody will probably see this. I guess I'll just go upvote a couple of people to make up for it.
