same with cats - unless you don't feed them, they have no need to kill birds

look at the audubon sites where they  BEG people to keep their cats indoors so they don't kill ANY birds.  or to put a bell on the cats' collars so the birds can hear them.

Cats are destroying the bird population which is already at risk.

The Effects of Cat Predation on Wildlife

from the USFWS Migratory Bird Mangement Office

Americans keep an estimated 60 million cats as pets. Let's say each cat kills only one bird a year. That would mean that cats kill over 60 million birds (minimum) each year - more wildlife than any oil spill.

Scientific studies actually show that each year, cats kill hundreds of millions of migratory songbirds. In 1990, researchers estimated that "outdoor" house cats and feral cats were responsible for killing nearly 78 million small mammals and birds annually in the United Kingdom.

University of Wisconsin ornithologist, Dr. Santley Temple estimates that 20-150 million songbirds are killed each year by rural cats in Wisconsin alone.

Feline predation is not "natural." Cats were domesticated by the ancient Egyptians and taken throughout the world by the Romans. Cats were brought to North America in the 1800's to control rats. The "tabby" that sits curled up on your couch is not a natural predator and has never been in the natural food chain in the Western Hemisphere.
