Yes, cats are killers when humans aren't around.
And that number is just for the US alone.
Quote:Previous studies had suggested that cats kill about 500 million birds a year. Marra's group came up with something very different. "We estimate that cats kill somewhere between 1.4 and 3.7 billion birds a year," Marra says. "For mammals, it's upward of about 15 billion."
Marra says based on those new figures, cat-caused mortality far exceeds deaths from other sources, like collisions with cars or wind turbines.
And that number is just for the US alone.
