The use of the phrase "mad as a sack of ferrets" emphasizes the character's vivid and somewhat amusing take on the situation, suggesting that the person is behaving in an erratic and unpredictable manner. It's a playful exaggeration that injects a sense of levity into the observation of someone else's fury.
