SQUIRRELS. Cute critters though they may seem when you see them scurrying about parks and trees, but their sinister side is never too far off: a pack of squirrels allegedly killed a stray dog in Russia, after a pine cone shortage drove them to extremes. And not just that, but they’ve been known to go after birds. And I need not remind you of my own close brush with Flying Squirrel Death when I encountered the Supreme Court Attack Squirrel. So now we know why White House grounds staff put out nut feeders: it keeps the murderous buggers off us and our pets!

Beware. A nearby squirrel may already have its eye on you.
