Think you know what your cat does when you're not around?
Cameras attached to the collars of 60 outdoor house cats have revealed what researchers are calling a previously unknown double-life as America's secret killing machines.
Researchers at the University of Georgia say the footage taken from cats allowed to prowl around Athens, Georgia revealed that 30 per cent killed an average of two animals a week.
The findings are described as astonishing by the researchers, as well as environmental activists, who say they're far beyond the figures previously believed.


'The previous estimates were probably too conservative because they didn't include the animals that cats ate or left behind,' UGA researcher Kerrie Anne Loyd told USA Today.
Instead the 3 ounce cameras - designed by National Geographic to be waterproof with LED night vision and radio trackers should they fall off - found that 30 per cent of cats ate their catch while the majority at 49 per cent left the carcasses to rot.

Just 21 per cent brought their kill home to their owners.
'Most of them left their prey. They would capture their prey, maybe play with it for a minute and then leave it close to the site of capture,' Ms Loyd told WXIA.

The kinds of creatures killed were largely made up of lizards, snakes and frogs at 41 per cent while mammals such as chipmunks and voles made up 25 per cent.
Insects and worms made up 20 per cent of their kills while 12 per cent were birds.
Despite birds making up only 12 per cent, with an estimated house cat population of 74 million across the U.S., conservationists link the kills to the decline in many American birds.
'Cat predation is one of the reasons why one in three American bird species are in decline,' George Fenwick, the president of American Bird Conservancy told USA Today.
With their surprising number of kills, the report also revealed a dare-devil side to the frisky felines.
'I knew that Booker T's favourite place was down in the storm sewer,' Amy Watts who owns three cats in Athens told WXIA, 'and now I know what the storm sewer looks like.'




Ms Watts, who volunteered her cats to the researchers' use, said she watched her cat’s camera footage take her virtually down there with him - creeping along the storm sewer's tight and dark tunnels, little to her comfort.
While 20 per cent of cats were found embarking on Booker T’s same love of storm drains, the most common deemed 'risky' behaviour by the cats, at 45 per cent, was crossing roadways.
Other less ideal behaviours to pet owners included 25 per cent of the cats eating and drinking things they found, and 20 per cent entering crawl spaces they could become trapped in.
