There are cat people and there are dog people, and the two groups have been arguing since humans started domesticating animals and using the ridiculously irritating term "pet parents." Well, dog people have just charted a major win.
A new study released by the Smithsonian Conservation Biology Institute shows that domestic cats are the No. 1 threat to wildlife in the United States, killing roughly 1.4 billion to 3.7 billion birds and 6.9 billion to 20.7 billion mammals each year.
In fact, the study states that more animals are killed by cats than are killed by cars, hitting buildings or by ingesting poison.
Researchers have been well-aware of the danger cats—especially strays—pose to native wildlife species. Cats are even credited as the cause of the extinction of 33 species around the world.
According to an article published by the BBC, native birds, mice, shews, voles, squirrels and rabbits were the species most likely to be killed by cats.
Researchers stated that there is an easy way to cut down on the wildlife carnage—cat owners just need to keep their cats inside. Or, of course, they could just get dogs.
