Never mind the bull in the china shop. For real destructive force, release a Great Horned Owl in a pet store.
Perhaps the fiercest creature with feathers, the Great Horned Owl hunts most North American animals: squirrels and jackrabbits, frogs and crayfish, even scorpions and spiders. A Great Horned Owl will kill smaller owls and hawks without hesitation, pluck crows from their roosts like hors d'oeuvres off a platter, and visit the nesting platforms of Ospreys for late-night snacks. Skunks, rabbits, rats, mice, and sometimes cats also have been known to find themselves in the clutches of the Great Horned Owl.
And if that weren't bad enough, since Great Horned Owl pairs start nesting early -- right about now, in fact -- they'll soon have more mouths to feed.
