Most cats do get scared of fireworks, but not all of them; many experience intense stress from the sudden, loud bangs and flashes, while a few seem barely bothered. It is safest to assume your cat will be scared and prepare accordingly, especially around holidays like New Year’s and the Fourth of July.

Why cats fear fireworks

  • Cats have very sensitive hearing, so fireworks can sound uncomfortably loud and threatening.
  • The noises are sudden and unpredictable, which naturally triggers a flight or “hide” response in many cats.
  • Bright flashes, vibrations, and strange smells (like gunpowder) add to the sense that something dangerous is happening.

Common signs your cat is scared

  • Hiding under beds, in closets, or squeezing into very small spaces.
  • Dilated pupils, pinned-back ears, low body posture, or an arched back and tense tail.
  • Changes in behavior such as pacing, excessive meowing, over‑grooming, or refusing food and interaction.

Are all cats scared?

  • Not every cat is afraid of fireworks; some will sleep through them, while others react as if it’s a major threat.
  • Fear of fireworks is considered a form of noise phobia, and sensitivity varies by individual temperament and past experiences.
  • Because you cannot predict a new cat’s reaction, it is wise to plan for a worst‑case (very anxious) response the first few times.

How to help keep them calm and safe

  • Keep your cat indoors well before fireworks start, and secure windows, doors, and cat flaps to prevent escape.
  • Create a safe hiding spot (quiet room, covered bed, cardboard box with blankets) and let your cat retreat there without forcing contact.
  • Use background sound (TV, music, white noise) and close curtains to muffle booms and block flashes.

Extra safety tips

  • Make sure your cat’s ID tag and microchip information are up to date in case they bolt and get lost.
  • For very anxious cats, talk with a veterinarian about calming supplements, pheromone diffusers, or short‑term anti‑anxiety medication.
  • Never let cats near active or spent fireworks, as they can cause burns or poisoning if chewed or eaten.

Bottom line: Yes, cats often do get scared of fireworks, so treating fireworks season as a potential stress event and preparing a calm, secure environment can make a big difference to your cat’s wellbeing.
