(Insane News) "Domestic cats are destroying the planet"

from i09

Our cats may be cuddly pals and adorable internet memes, but they are also destroying the environment more efficiently than humans. They have been called one of the "worst" invasive species. And a new study published today in Nature Communications suggests that cats are responsible for killing several endangered bird species in the United States, and decimating bird populations on islands all over the world. In the US, cats kill as many as 3.7 billion native birds annually, making them a bigger threat to these creatures than buildings, towers, windows, poison, and cars. But there is a solution to the problem.

The biologists who worked on the new study pored over research culled over the past several years to estimate how many cats live in the US, and what their killing habits might be. They estimate that roughly 84 million owned cats live in the US, and that there are 30-80 million un-owned cats, which include feral cats, barn cats, and cats who are not allowed inside. The researchers "estimate that free-ranging domestic cats kill 1.4–3.7 billion birds and 6.9–20.7 billion mammals annually." They emphasize that "un-owned cats" are the culprits here. Though the numbers may be shocking, their discovery isn't particularly startling. Un-owned cats have already been implicated in 33 modern bird, mammal, and reptile extinctions, write the researchers in Nature Communications...
