Final answer:
Rats steal food and provisions like grains and meat from human storage, granting them a human-like living condition.

The rats mentioned in the student's question steal food and provisions regularly from Farmer Fitzgibbon. Although the exact resources are not detailed in the given text, we can infer from historical contexts and the examples provided that grains, meat, and other staples stored by humans are often targeted by rats. This thievery would allow rats to live with a degree of comfort and stability, mimicking human-like conditions of food security.
