Scientists with the Smithsonian Conservation Biology Institute and the Fish and Wildlife Service estimated that the median number of birds and mammals killed annually by cats is 2.4 billion and 12.3 billion respectively. They made this shocking assertion in a new study published in the journal Nature Communications.
Cats kills more birds and mammals the scientists said, than auto collisions, pesticides, poisons, or flying into skyscrapers, windmills or planes. These kitties kill more of these animals than any other human-related killers, wrote Peter Marra of the Smithsonian Conservation Biology Institute and Scott R. Loss, and Tom Will of the Fish and Wildlife Service.
They included cats that live in our homes and feral cats in their estimate.
