Key Takeaways
Can cats wear ear defenders? Technically a small cup can sit on a cat’s head, but no cat ear defenders are designed or tested for cats, most cats will not tolerate them, and holding a frightened cat still to fit one does more harm than good. We say this as people who make ear muffs for dogs.
At BOLLSEN we are a family-owned hearing protection company, founded in 2016 and trusted by 1,000,000+ people, and dog hearing protection is part of what we make. We make no product for cats. Our dog muff page often appears when people search for cat ear defenders, so here is our honest answer and what helps a cat instead.
Can cats wear ear defenders?
Cats can’t wear ear defenders in any reliable or recommended way, because no product is designed or tested for a cat’s head and ears, most cats claw at anything on their head, and fitting one means restraining an animal that copes by hiding.
Some marketplace listings sell small pet muffs as “for dogs and cats”, without any fit or tolerance evidence for cats that we have seen. When a pilot on an aviation forum asked how to protect his cat’s hearing on light-aircraft flights, the most practical reply was not a muff at all. It was a blanket the cat could crawl under when it got too loud.
Why are cats harder to fit than dogs?
A cat’s pinnae (ear flaps) move independently to locate sound and to signal mood, its head is far smaller than most dogs’, and its coping style is to hide rather than settle under handling, so a cup over the ears blocks the very tool the cat relies on.
The Merck Veterinary Manual notes that a cat’s left and right pinna can move independently to help locate sounds, and that the ear canal is deeper than a human’s. Flattened ears are also how a cat shows fear, and a cup hides that signal. The LSU School of Veterinary Medicine lists a cat’s hearing range as 45 Hz to 64,000 Hz, wider at the top than a dog’s 67 Hz to 45,000 Hz.
A dog can learn to accept a headband with food rewards, and its larger head gives a cup something to seal against. Our guide asking can dogs wear earplugs explains the canine ear canal and why over-ear muffs suit dogs instead.
What about earplugs or cotton wool for cats?
Never put earplugs, cotton wool or anything else into a cat’s ear canal, because the canal is narrow and deep, a cat will shake and paw at it, and an object pushed inwards can lodge where only a vet can safely remove it.
“Earplugs for cats” is a real search, and we understand the instinct. Human headphones slide straight off a cat’s head too. If your cat keeps shaking or tilting its head, book a vet appointment rather than reaching for tweezers.
Do cats hate fireworks?
Many cats are frightened by fireworks, and they tend to show it by hiding and cowering rather than pacing or barking, so a cat that vanishes under the bed on Bonfire Night is usually telling you it is scared.
A New Zealand survey by Dale and colleagues (2010) covered 3,527 dogs and cats in 1,007 households and found that 46% showed fear of fireworks their owners could recognise. Cats were more likely than dogs to hide and cower. The study also linked comforting a fearful pet with owners reporting the fear worsening over time, an association rather than a rule.
What actually helps a cat through fireworks and thunder?
What helps a cat is a hiding place set up days ahead, ideally high and enclosed, plus keeping it indoors after dark with a litter tray, curtains drawn and steady background sound to muffle the bangs, so the cat can choose where to ride out the noise.
Battersea suggests a blanket-lined box with the opening slightly covered, noting that cats feel safer the higher up they can go. It also advises against picking up a stressed cat, as that can provoke sudden aggression, and to block off the cat flap. Cats Protection adds fastening doors and windows, drawing the curtains and playing soothing music.
Weeks before the season, some owners play firework recordings very quietly at mealtimes and raise the volume slowly. Ask your vet before you start.
| Option | Suits cats? | Why |
|---|---|---|
| Hiding place, high and enclosed | Yes | Matches how cats cope; the cat chooses when to come out |
| Curtains drawn, steady background sound | Yes | Hides flashes and muffles bangs without touching the cat |
| Ear muffs or ear defenders | No | None designed or tested for cats; fitting means restraint |
| Earplugs or cotton wool | No | Anything in the ear canal can lodge and need a vet |
Should your cat be microchipped before fireworks night?
Yes, a microchip is your best chance of getting a cat back if it bolts during fireworks, and in England it is now a legal requirement, so check the chip is registered and your contact details are current before November.
According to GOV.UK, cat microchipping became compulsory in England on 10 June 2024 for cats, which must be chipped by the age of 20 weeks, with a fine of up to £500 for owners who do not comply. If your cat stays unsettled for days afterwards, talk to your vet.
What if you also have a dog?
If you share your home with a dog as well, an over-ear muff made for dogs is an option for the dog, and our Dog+ is designed for dogs, not cats, so please keep it on the dog and give the cat its den.
Dogs often show fear by pacing or panting, and our guide to noise anxiety in dogs covers the signs and when to bring your vet in. For a firework night plan in a house with a dog, see our guide to dogs and fireworks, from preparing months out to the morning after.
Our Dog+ earmuffs for dogs (SNR 27 dB, sizes XS to L, £69.95) are sized for dog heads only. The frequency data showing how much noise dog ear muffs reduce explains why the low thump of fireworks gets through most. For the decibel levels behind all of this, see how loud is too loud for dogs.
Your cat is rarely the only one awake on Bonfire Night. If the bangs keep you up too, our guide to earplugs for sleeping is for the humans of the house.
So, can cats wear ear defenders? Not in a way we would ever suggest, and we make no cat product. Give your cat a high, covered hiding place, keep it in after dark with the curtains drawn, and check the microchip. Then let your cat decide how close to the noise it wants to be.
