Also, safety plans should cover the animals outside as well as the one beside you on the sofa. Keep cats indoors before dark, and bring rabbits, guinea pigs, and other small pets into a sheltered, quiet area before fireworks are likely to start. Check that doors, hutches, runs, and garden gates are secure, since a frightened animal may try to hide or escape.
Avoid leaving pets alone where possible, especially during the noisiest part of the evening. If you need to go out, ask a trusted adult to stay with them, leave their safe space ready, and keep your contact details available. A calm person nearby can notice distress early and prevent risky behaviour such as chewing, scratching, or bolting.
That said, a little fear is different from severe or repeated anxiety. Contact a veterinary professional if your pet repeatedly panics, hurts itself, cannot settle for hours, stops eating, or reacts strongly to loud sounds long after the fireworks have ended.
If you do one thing, record what you notice: the time the noise began, your pet's behaviour, how long it lasted, and what helped. This gives the veterinary professional useful detail and can help you make a clearer plan for the next firework night.
