I’ve blogged before on the impact of free-ranging domestic cats on wildlife (https://blogs.nicholas.duke.edu/citizenscientist/songbird-its-whats-for… ). In China, a new study estimates annual bird mortality from cats at 2.7 to 5.5 billion birds each year. Recent reports document a loss of about 30% of the birds from North America since 1970, and undoubtedly cats have played a significant role. Cameras mounted on collars (Kitty cams) document the hunting behavior and predatory success of cats. Cat predation averages 3.5 prey items per month, as reported by a worldwide survey of Citizen Scientists. Cat owners have a variety of reactions to these statistics, ranging from denial (“my cat would not kill a thing”) to support (“I like my cat to live by its evolutionary instincts”) to deep concern (“I try to keep my cat indoors and bells would be a good addition to its collar”). While, for years, dog owners have tolerated lease-laws, many cat owners are opposed to generic restrictions against free-range behavior. Human sympathy for cats extends to feral cats, where at best we find policies for “catch-neuter-and release”. Declawing the animal is never discussed; the cat is returned to feed on nature. Cats are impossible to discipline, but why do we give cats a full pardon for their actions? Most cat owners do not relish the predation by their pets, and many indicate they would accept policies that would require a bell on cats’ collars. This is an easy, low cost first step to reducing a widespread human impact on nature. Next time you see a cat stalking in your yard, give a bell to its owner with instructions on how to install.
