ABC report on outdoor cats
This report reviews cat predation impacts on rare birds in the states of New York, New Jersey, Florida, California, and Hawaii, reviews government-authorized programs and ordinances affecting feral and free-ranging cats and their management, and makes recommendations on better ways to manage cat overpopulation problems.The review looks at species such as Piping Plover, Common Tern, Florida Scrub-Jay, California Clapper Rail, Wedge-tailed Shearwater and numerous Hawaiian endemics.
After reading the report, please consider sharing details with local trap/neuter/release programs (perhaps a veterinarian can point you to them) and with the staff at pet stores, who can encourage customers to keep their cats indoors. (Besides, indoor cats need more toys and other products to remain stimulated and happy ;)
Just to clarify: I have nothing against cats, just the humans who let them roam outdoors. Kitties should be contained in safe environments where they can't be harmed or harm other critters.
