I wouldn't consider squirrels to be a positive thing.
You ever had those tree-rat bastards trying to start up families in your attic? What about the flying sort? They're pretty cute, but when you're forced to choose between starving them out (TERRIBLE OPTION OH GOD WHAT WAS I THINKING CRITTERS ARE LOUD WHEN THEY DIE FROM MALNUTRITION), using poison, or shooting them in such an enclosed space you're likely to hear EEEEEEEEEEEEEEEEEEEEE for a week....you start to dislike squirrels.
So yeah, FUCK some squirrels, man.
