Seems to be an incredibly biased article. Most people would not consider a cat killing a mouse as a damage to wildlife. While it's true to the meanings of the words, it misses the principle. People building houses and poorly storing food also causes an increase in the mouse population by increasing the abundance of food and nesting areas. And killing mice is one big reason a lot of people get a cat at all. They've also assumed that all kills are equal, e.g. a cat killing a mouse is considered the same as a wildcat killing a coyote, or opossum. I'm not doubting cats have some impact, but I'd be willing to bet it's trivial compared to the human impact. And if you're looking for ways to lessen the impact, your cat is likely one of the last things to consider.
