Give them a 'safe place' to hide - it should be quiet and accessible to them at all times.
Keep your cat or dog indoors when fireworks are being let off and bonfires are lit.
Use a litter tray at this time of year to keep your cat safely indoors.
Block flashing lights
Close your windows and pull the curtains to stop flashing lights startling your pet.
Don't fuss your pet if it's showing signs of fear - the RSPCA advises against this as it will make things worse in the long run, and your pet needs to get used to loud noises.
Keep them occupied
In a bid to distract your pets, there's nothing wrong with giving them a new toy or tasty treat to keep them occupied.
Pets that live outside?
Partially cover the cage and put down extra bedding for them to burrow in.
Make sure they're secure - you don't want them running away after a sudden noise.
