Feral cats, as well as domestic house cats, have a significant impact on wild birds and other small wildlife.  Estimates are that free-roaming cats kill hundreds of millions of birds each year.  These include common species such as Robins and Mourning Doves, but also threatened and endangered species such as Piping Plovers and those in decline, including Wood Thrushes and Black-throated Blue Warblers.

In January 2003, the Federation sent a letter to the Commissioner of the NY State Office of Parks, Recreation and Historic Preservation urging the elimination of feeding stations for feral cats in state parks.
