Tom found acorns that the squirrels were hiding in a log cache. They were very upset that the food was being stolen, but they dare not mess with a raccoon.
Despite being small, raccoons are predators. They could easily gobble up a small animal, like a squirrel.

As you can see they have sharp front teeth for tearing meat and flat back teeth for grinding up plant material.
