Birds and Outdoor Cats
No bird-enthusiast likes it when their cat kills a wild bird. But they may be unaware just how harmful cats can be on bird populations. Many bird species are reduced in number, or have even become endangered, because of outdoor cats. In fact, one study calculated that in the U.S. state of Wisconsin alone, rural cats may be killing up to 219 million songbirds each year. Another study in England followed 964 free-roaming cats for five months. The cats killed 14,000 animals, 3300 of which were wild birds.
