Mischief night is 4th November in Yorkshire, not 30th October.
I wonder if Mischief Night on 4th November is all that remains of the former holiday of Hallowe'en, which may have died out with the Reformation?
It has always been the night before Hallowe'en in the US, with the concept of a night of mischief and mayhem probably imported from RC areas of Europe, mainly Ireland. The city of Detroit had a major issue with arson and criminality on Devil's Night as Mischief Night is known there, well into the 1990s.
Hallowe'en itself used to feature far more mischief up to about the 1970s in the US and Ireland (where it has always been a fixture). RC Church authorities tried hard to eliminate the secular Hallowe'en celebration that was very boisterous bordering on outbreaks of criminality, in favour of the religious feasts of All Souls and All Saints. In the US the holiday was a major nuisance and was gradually transformed into the very tame candypalooza that it now is, and that spread to Ireland and apparently recently became re-established in many parts of Britain.
I have a little black indoor cat. She finds the 4th of July terrifying, but Hallowe'en isn't really a fireworks night in the US.
So sorry to hear of the attack on your poor cat, Babababababybel23.
I really would be careful about pets on Hallowe'en. You never know who they will run into. Better safe than sorry.
Thanks to the OP for posting.
