Acting Like Animals: File Under 'F'

Yes, human, I'm presently occupying the space where your documents that start with the letter "F" usually go. "F," as in "feline" and "feed me" and "food" and "ferocious when hungry." I know you're not so good about picking up on subtlety though, so I took the liberty of leaving some "presents" in the folders for "H" as in "hungry," "N" as in "noms" and "C" as in "can opener" to help get my point across.
