Raccoon learns to knock at the door using a stone to beg for food

This could be any homeowners nightmare.

Imagine sleeping at night and you hear someone's knocking at your backyard door. And it's a raccoon. Begging you to give him food.

But since it's so cute, you obliged. You give the cute raccoon a bowl of cat food. Just wait until it comes back every night and you finally realize it's not so cute anymore.
