the studies on which these claims are based are poor. but they generated sensenationalist headlines... and for the reading public that's all that counts, sensationalism. they basically took a small sample of the study and generalizzed it across the entire nation... which is absurd as populations and enviorments are radically different. cats live where people live... they don't live in yellowstone.

the more sober studies on the issue basically show that whiel the vast majority of cats kill some birds, most are not bird serial killers. a small percentage however, are.
