Billions of Birds
29 January 2013
– 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).

Cats should be kept indoors.
We are asking all municipalities to make a requirement for all cats to be licensed.
