Study: Cats wiping out backyard wildlife

Cats can be cuddly, but America’s second most favorite family pet is also an accomplished killer.

Researchers at The University of Georgia have concluded domesticated cats are wiping out neighborhood wildlife.

USA Today sums it up as mundanely as possible: “That mouse carcass Kitty presents you with is just the tip of a very bloody iceberg. When researchers attached kittycams to house cats, they found a secret world of slaughter.” [Video of the carnage]

While icebergs are largely homogeneous in structure, the wildlife gnawed upon by Fluffy is quite diverse.

Mammals’ eternal foe, the reptiles (and their slimy cousins, the amphibians), take the brunt of the feline assault — lizards, snakes and frogs made up 41% of the animals killed by the 60 Athens-area cats equipped with collar cameras.

Cute creatures, such as chipmunks and voles, made up 25% of the tiny corpses; insects and worms 20%; birds 12%.

I’d have thought birds, as tasty as they are, would have been killed more often, but, from a predator’s standpoint they have the annoying ability of flight.

Nevertheless, birding enthusiasts are upset at the nation’s 74 million cats.

“Cat predation is one of the reasons why one in three American birds species are in decline,” said George Fenwick, president of American Bird Conservancy.

Cat lovers are equally upset at the UGA report, which has been called “heavy on errors, misrepresentations, and glaring omissions, and light on defensible claims.”

Here’s some more details from the complete UGA study that will make you think twice about kissing Fluffy:

  • About 30% of roaming house cats kill prey — an average of two animals per week
  • Cats brought home just under a quarter of what they killed, ate 30% and left 49% at the scene of the crime
  • Roaming cats are a lot like roaming people — males were more likely to take risks than females and older cats were more careful than younger ones.
  • Favorite risky behaviors include crossing roadways (45%), eating and drinking things they found (25%), exploring storm drains (20%) and entering crawl spaces (20%)

[...] additionally noted males were some-more approaching to rivet in “risk behavior” than womanlike cats [...]

Every week, there’s a new “cat missing” sign at the entrance to my subdivison. Two doors away, my neighbor’s cat was killed by a coyote a year ago in her driveway and one of my neighbors will not walk her dog along the river trail in my backyard as the coyotes attacked one of her dogs. Seems like if one predator gets an advantage, another comes along to get things back in check. You need some coyotes in Athens, then replace them will wolves, then prides of lions, then …..hood rats???

Spay/Neuter of feral cat colonies is a waste of effort and money. That is the conclusion drawn from long term studies. Just trap and euthanize. Sorry, but that is effective. Coyotes are also effective.
People just need to neuter their pets, and keep their pet cats indoors. That measure protects the owners and neighbors from toxoplasmosis.

Every week a cat disappears in our subdivision. We have coyotes who killed a neighbor’s cat in her driveway. Our neighbors quit walking their dogs along the river trail in my backyard as the dogs were attacked but did survive. Seems like a predator that gets an advantage soon has another predator on their case. Athens needs to import some coyotes, then they can get wolves and later bring in prides of lions. After that, the hood rats will clean house. Nature works wonders.
