Feline Hearing - How well can your Cat hear?

By Sophie Kininmonth · 31 Dec 2025 (updated 21 Jul 2026) ·6 min read

A cat's hearing is one of the sharpest tools in the animal world, reaching well past the range humans can detect and helping cats pinpoint the faint rustle of prey long before they see it. Most owners only start paying attention to it when something changes: the cat sleeps through the tin opener, startles at a touch, or seems to ignore a familiar voice. Some of that is ordinary ageing, and a hard-of-hearing cat can live a comfortable life indoors. The catch is safety, because a cat that cannot hear a car or a dog coming is at real risk outside. This guide covers what normal feline hearing looks like, what changes with age or illness, and how to keep daily life calm and safe if your cat is losing it.

How a cat's ear works

A cat's ear does its job in three stages: the outer ear gathers sound, the middle ear passes on and amplifies the vibration, and the inner ear turns that vibration into nerve signals the brain reads as sound.

Outer ear: the pinna (ear flap) funnels sound into the ear canal.
Middle ear: the eardrum (tympanic membrane) vibrates, and tiny bones transmit and amplify those vibrations.
Inner ear: the cochlea converts vibration into electrical signals carried by the auditory nerve.

Hearing loss happens for one of two reasons. Either sound cannot reach the inner ear properly (wax, inflammation, infection), or the nerve cells responsible for hearing are damaged, which is often permanent.³

The range of feline hearing

Cats hear a broader span of frequencies than we do, especially at the high end. In controlled measurements, domestic cats detect sounds from roughly 48 Hz up to about 85 kHz at typical test levels.¹ For comparison, humans usually hear from about 20 Hz to 20 kHz. Cats overlap us at the low end but reach far higher.¹

That high-frequency reach explains why a cat can notice tiny, sharp sounds, like the squeaks of small prey, while we hear nothing at all.¹ Cats are also good at working out where a sound comes from, helped by mobile ear flaps and quick processing, which matters when something moves out of sight.²

One correction worth making: strong directional hearing does not mean a cat can find its way home when lost. Cats do sometimes return, but that is not reliably explained by hearing, and it is not something to count on for safety.

How cats use hearing when hunting

When a cat hunts, hearing usually gives the first clue that something is nearby. The cat pauses, ears swivelling, then shifts position to refine the direction before switching to vision and whisker touch at close range.

This is why some hard-of-hearing cats still chase toys effectively indoors, because the other senses compensate. The same cat can be vulnerable outdoors, where hazards arrive fast and without warning.

Common hearing problems in cats

Deafness (congenital or acquired)

Deafness may be present from birth or develop later. Congenital deafness is more common in cats with certain coat and eye-colour genetics, for example some white cats with blue eyes, though not every white, blue-eyed cat is deaf.³

Acquired hearing loss can be linked to causes such as:

Ear canal blockage (wax, debris, polyps) or chronic inflammation (otitis externa).³
Middle or inner ear infection (otitis media or interna).³
Trauma or tumours affecting the ear or related nerves.³
Ototoxic drugs (some medicines can harm hearing).³
Age-related change (hearing often fades gradually in older cats).³

Some hearing loss improves once the underlying blockage or inflammation is treated. Nerve-related (sensorineural) deafness is usually permanent.³

Tinnitus

True tinnitus, a ringing or buzzing perception, is hard to confirm in cats because we cannot ask what they hear. If your cat shows persistent ear discomfort, head shaking, sudden sensitivity, or changes in balance, treat it as a medical problem worth checking promptly rather than assuming tinnitus.

How to tell if your cat is losing hearing

Hearing loss in cats is often subtle, especially if only one ear is affected. The clues tend to show up as patterns over time:

Sleeping through noises that used to wake them (food prep, the doorbell, your voice).
Startling when touched, especially if approached from behind.
Not turning the ears or head towards sounds, or turning the wrong way.
Louder vocalising than usual, as some cats meow more strongly when they cannot hear themselves.

A vet can check for treatable causes such as wax, infection and inflammation. Specialised testing (such as BAER) may be used to confirm and characterise deafness, particularly when loss in one ear is suspected.⁴

Keeping a deaf or hard-of-hearing cat safe

The single biggest safety shift is to assume your cat cannot hear danger coming. For many cats that means an indoor-only life, or a secure outdoor enclosure.^{3, 5}

Practical safety habits that help

Containment: keep your cat indoors, or provide a fully enclosed catio or run for outdoor time.^{5, 6}
Identification: microchip your cat and keep the registry details current, and use an ID tag on a breakaway collar where appropriate.⁷
Startle prevention: approach within their line of sight, switch on a light before touching them at night, and use gentle floor vibrations (a firm foot tap) to announce yourself.^{8, 9}
Household routines: keep the furniture layout consistent so the cat can navigate confidently.

Protecting hearing: what is realistic

Everyday household noise (television, music, the vacuum) is unlikely to cause deafness in a healthy cat by itself, though sudden extreme noise can be harmful and noise stress still matters for welfare. The more practical protection is medical and environmental: keep the ears healthy, and avoid situations where hearing would be needed to detect danger.

Do not put ear muffs or ear plugs on your cat unless a vet has specifically advised it. Poorly fitted gear can trap moisture, irritate the ear canal, and make infections more likely.

Training and communication when hearing fades

Cats pay close attention to routine, body language, and small changes in the environment. When hearing is limited, move your cues to what they can reliably detect:

Hand signals for come, up, food and stop. Keep them consistent.
Light cues (a lamp flicked on and off) to get attention without startling.
Vibration cues (a gentle foot tap on the floor) to prompt them to look around.⁹

Reward calm attention with food, play, or a scratch under the chin. Keep sessions short. Cats learn best when the house is quiet and the request is clear.

When to see the vet soon

Book an appointment promptly if you notice any of the following:

Sudden hearing change over hours or days, especially with a head tilt or loss of balance.
Ear discharge, bad odour, redness, swelling, or obvious pain.
Persistent head shaking or scratching at the ears.
Hearing loss after starting a new medicine (do not stop medications without veterinary advice).³
