This may be a little late for this year as both Diwahli and November 5th have passed, but the comment is still worth making and hopefully people will keep it in mind for the future.
I have been hearing some truly upsetting tales about dogs and other pets which have been injured because of their sheer panic at the noise.
Firework displays can be great fun and are a good chance for the community to gather together, but most people are within range of an "official" display at a school, social club, village field or similar. It would be nice if people would support those events and forgo letting fireworks off at home; you can still celebrate with friends before or after the official displays without the need for fireworks in the back garden. That way, there is some predictability around when the noises will be happening and people caring for nervous animals have a chance to deal with the problem. What seems to happen now is that there are fireworks let off at random times every night for what is apparently an increasingly extended period every year, making the disturbance impossible to predict.
