When she's on a mission for food, 'Rocksy' the raccoon has a rock solid way to alert a homeowner she needs to be fed.

This persistent raccoon has more at stake than her own appetite. She also has a family to feed. This smart mamma figured out if she makes an incredibly annoying knock on the door with a rock, sooner or later she'll get what she's looking for.

The homeowner, who points out the scratches on the door glass, actually seems to enjoy this animal's knocking, which apparently will continue - for hours -  until she gets fed. That's a raccoon who's living up to her name, 'Rock-sy'.
