It is not only animals that are effected, as Willow has already mentioned. My niece has profound learning difficulties and reacts so badly to fireworks, screaming, crying, throwing herself about and tearing her clothes. This goes on for hours. She cannot understand any explanations and her parents have tried all kinds of things to help her manage, without avail. When Bonfire Night goes on for many days, and birthday parties include fireworks, it is difficult to plan for these unexpected/spontaneous noise fests. No One sleeps . It is torture.
