We live about 1/2 mile from a very big firework factory so we hear them being tested all year round and the pets have learned to ignore them, unfortunately they have a factory shop where they sell them very cheaply everybody locally gets loads of them so we will hear them going off around the house until the early hours. Totally agree with marlynaveve they should be restricted to organised displays. Last year a local boy found a yorkie that had been killed by a car and blew it up with a firework so the poor owner didn't even have a body to bury.
