A peer-reviewed study published in the journal Nature Communications
reports that outdoor cats are the greatest source of human-caused
mortality for birds and mammals in the U.S.
Research scientists from the
Smithsonian Conservation Biology Institute and the U.S. Fish and
Wildlife Service’s Division of Migratory Birds reviewed 90 previous
studies and found that free-ranging cats cause substantially greater
wildlife mortality than previously thought. They estimate that
free-ranging domestic cats kill 1.4-3.7 billion birds and 6.9-20.7
billion mammals annually in the U.S., with about 69% of bird mortality
from cat predation and 89% of the mammal mortality caused by un-owned
cats (rather than owned pets).
