Using deliberately conservative assumptions, federal researchers recently estimated that free-ranging cats killed about 2.4 billion birds annually in the Lower 48 states, a substantial bite out of the total bird population. Outdoor cats also kill about 12.3 billion small mammals a year — not just the proverbial rats and mice but also chipmunks, rabbits and squirrels — and about 650 million reptiles and amphibians. In some cases, they are pushing endangered species toward extinction.
