Your cat is an ecological disaster

Cats kill birds. lots of birds.

From the New Yorker article

“And how many birds does a bird-killing cat kill in one year? (Perhaps three dozen.) Each of these multipliers had a range of uncertainty, so the model needed to be run repeatedly. The number it generated most often was 2.4 billion birds a year. Outdoor-cat advocates were quick to dismiss the paper as ‘junk science.’… But I, too, at first, being skeptical of models, had trouble believing that the numbers could be so vast…. The most dismal number in the Nature Communications paper was its median estimate for the birds killed annually by cats with owners: six hundred and eighty-four million. 

Because I’m a heartless bastard, I suggest a modest bounty on stray cats, say $5 a head. Might as well give our indigents and underemployed youth something constructive to do.
