Why Are Cats Scared of Thunder and Fireworks?

“Scaredy cat” is a phrase coined by author Dorothy Parker from her short story, “The Waltz.” And all cats, with their senses intact, put truth to that phrase.

Many cats are sensitive to loud noises, especially sudden ones they can’t predict or escape. Thunderstorms, fireworks, construction sounds, and even loud household noises can trigger fear and stress in cats.

So why are cats so afraid of loud noises? Part of it comes down to instinct. Cats are wired to stay alert to potential danger, and unfamiliar booming sounds can feel threatening to them.

Here, our experts explain why cats react so strongly to thunderstorms and fireworks, signs your cat may be scared or anxious, and simple ways you can help them feel safer and calmer when loud noises strike.

Are Cats Afraid of Loud Noises?

Cats are often fearful of loud noises including fireworks and thunder, even in the comfort of their own homes. Their stress can amplify if they are somewhere unfamiliar, and they don’t have a place they know they can hide. Cats also have sensitive hearing, so loud noises can feel overwhelming to them in a way that might not be to humans.  

Why Are Cats Scared of Thunder and Fireworks?

Cats can sense weather changes. A cat scared of storms might act strange before bad weather happens. Like many other animals, cats can sense changes in atmospheric pressure from thunderstorms, sometimes causing a seemingly premature flight response.

Unpredictable and loud noises can trigger a flight response, which is why cats are afraid of fireworks. The same logic applies with vacuums and other loud noises. Even though we know they are harmless, loud noises can trigger them. If your cat came from a previously abusive environment, it could also exacerbate their fear of loud noises.  

Signs of a Scared Cat

Signs of fear in cats may include but are not limited to:

• Hiding
• Shaking
• Excessive grooming, when cats lick their fur so much that it causes hair loss
• Panting
• Drooling
• Increased vocalizing
• Inappropriate defecation
• Inappropriate urination
• Destructive behavior
• Increased heart rate
• Decreased appetite

These behaviors are a way to express their fear and discomfort.

How to Calm a Cat During Thunderstorms and Fireworks

Ways to calm a cat during thunderstorms and fireworks can include natural remedies, behavioral training techniques, and more.

Calming Supplements

Supplements, such as Calming Care Cat Probiotic Anxiety Supplement from Purina Pro Plan Veterinary Supplements, can help promote calm behavior in cats displaying anxious behavior.

Pheromone Products

Synthetic pheromone-based diffusers can work on some cats who find the scents calming, though they are not for every cat.  

Thunderstorm Jackets

A cat thunder jacket, or a compression vest, can ease anxiety in stressful situations.

Playing with Your Cat

Playing with your cat may help them relieve stress while keeping them stimulated. It also helps you connect with them. If you’re calm around your scared cat, they’ll feel safer.

Creating a Safe Space

Try creating a safe space where your cat can hide during loud noises like thunderstorms, such as in a bedroom or office. They enjoy being high off the ground, and it makes them feel safe. Treats can help lure them to a safe spot if they are scared.

Seeking Professional Help

If your cat continues to exhibit stress and has ongoing side effects, like alopecia, it’s a good idea to see a veterinarian. A veterinarian may refer you and your cat to a veterinary behaviorist to help tackle the side effects of stress and identify any other possible root causes.
