This menace may purr and play with balls of string, but it is still a formidable and dangerous hunter. It is Felis domesticus , the common house cat. This is a misconception because a ringing bell is not an instinctive danger signal for birds and wildlife. Cats are not natural predators of the environment and often they will not even eat what they have hunted, wasting food resources. One female and her offspring are capable of producing 420,000 cats in only 7 years.
Cats kill millions of songbirds each day.
Even larger birds such as waterfowl and raptors become prey. A cat kept indoors is much healthier than a free-roamer. Felines kept in the house are also protected from cars, the worst enemy of cats. A bout 1.5 million cats a year are killed by cars. Free-roaming cats also run a higher risk of exposure to parasites and diseases like rabies.
