# Signs Your Cat Is Going Deaf: Symptoms to Watch For Deafness in cats means partial or complete hearing loss in one or both ears. The most common signs of cat going deaf are ignoring sounds that used to get a reaction, sleeping through noise, and vocalizing more loudly. Some cats lose hearing slowly over months or years, while others go deaf within hours or days, and that sudden form can signal an emergency. This article is educational and is not a substitute for veterinary diagnosis or treatment. ## Quick Answer - A cat that no longer turns toward your voice, the doorbell, or a bag of treats may be losing hearing. - Gradual hearing loss is common in older cats and often gets mistaken for stubbornness or "just getting old" [1]. - Sudden deafness, especially with head tilt, circling, wobbling, or vomiting, needs a veterinarian right away. - White cats with blue eyes are more likely to be born deaf, but most deaf cats are not white [2][3]. - Never test hearing by making loud noises near your cat's head, and never put anything inside the ear canal. ## What Hearing Loss Looks Like in Cats Cats hide hearing loss well. A deaf cat still watches your body language, feels floor vibrations, and follows other pets. In a group, a deaf cat can copy the others and go completely unnoticed [2]. ### Early signs of deafness in cats You may notice small changes first: - Your cat stops reacting to the sound of a can opening or a treat bag. - Your cat sleeps through noises that used to wake them. - Your cat no longer comes when called, even from the same room. - Your cat startles when you touch them or walk into view. - Your cat watches your face and hands more closely than before. ### Signs that appear as hearing loss gets worse - Loud, drawn-out meowing. Cats that cannot hear themselves often turn up the volume. - A blank stare when you speak. Your cat sees your mouth move but does not turn toward the sound. - Trouble waking up. You may need to touch your cat or stomp on the floor to rouse them. - One-sided deafness. Your cat may respond only when you call from one side of the room [2]. - Changes in play or hunting. Toys with bells stop being interesting. ### What is normal It is normal for any cat to ignore you sometimes. A healthy cat with normal hearing still reacts to sudden sounds when they are not focused on something else. The pattern matters more than any single moment. If your cat responds to sound most of the time but misses it occasionally, that is different from a cat who never responds. It is also normal for senior cats to slow down. Aging does affect hearing, and age-related changes in the inner ear have been documented in cats, similar to what happens in older people and dogs [4]. That does not mean every senior cat is deaf, but hearing decline becomes more likely with age. ## Causes of Deafness in Cats Deafness can be present at birth or develop later [2]. The cause shapes how fast it happens and how urgent it is. | Cause | Typical clues | How urgent | |---|---|---| | Born deaf (congenital) | White coat, often blue eyes, no response to sound since kittenhood [2][3] | Routine visit to confirm | | Inherited inner ear condition | Young cat with deafness plus balance problems [5] | See a vet soon | | Earwax or debris blocking the canal | Head shaking, scratching, odor, visible debris | Routine to same day | | Outer ear infection | Redness, discharge, rubbing the ear | Same day to a few days | | Middle or inner ear infection | Head tilt, loss of balance, nystagmus (eyes flicking) | Same day | | Inflammatory polyps | Young cat, discharge, breathing or swallowing changes | Same day | | Trauma or head injury | Recent fall, hit, or fight | Emergency now | | Toxins or certain drugs | Known exposure or new medication | Emergency now | | Aging | Slow decline over months, no pain, no discharge [4] | Routine visit | ### Congenital deafness Some cats are born deaf. This can be inherited or caused by damage before birth from a virus or a poisonous substance [2]. White cats with blue eyes are more likely to be affected, but the link is not absolute. In one study of purebred white cats, about 17% were deaf [3]. In a study of white Devon Rex cats, about 10% were deaf, and blue eyes did not predict deafness in that group [6]. Cats with this condition are born deaf or lose hearing within the first 4 to 5 weeks of life [3]. A genetic variant affecting the inner ear has been identified in a young cat with deafness and balance problems, which shows how hearing and balance are linked [5]. ### Ear infections and blockages Many cases of acquired deafness come from something blocking or damaging the ear. Chronic outer ear infection, middle or inner ear infections, excess earwax, and damage to the tiny ear bones can all cause hearing loss [2]. Inflammatory polyps, which are growths in the ear or throat area, can also cause deafness [2]. The good news is that many of these cases improve. Removing the blockage or healing the damaged tissue often restores hearing [2]. If your cat has discharge, odor, or head shaking along with hearing changes, see these guides on [Symptoms Of Cat Ear Infection](/knowledge/veterinary-medicine/symptom-guides/symptoms-of-cat-ear-infection) and [Cat Head Shaking and Ear Problems: What to Know](/knowledge/veterinary-medicine/skin-allergy-and-ear-care/cat-head-shaking-ear-problems). ### Aging Hearing loss in older cats is common and often gradual. Research on the feline middle and inner ear found that older cats develop thickening of the basilar membrane and shrinkage of the stria vascularis, the same kinds of changes seen in aging humans and dogs [4]. These changes are not painful and cannot be reversed, but they can be managed well at home. Sensory decline in older pets is often missed or mistaken for cognitive dysfunction or normal aging [1]. If your senior cat seems "checked out," hearing loss may be part of the picture. ### Sudden deafness in cats Sudden deafness in cats is different from the slow decline of aging. It can happen with inner ear disease, a polyp, trauma, a toxin, or a drug reaction [2]. It can also come with balance problems, which points to the inner ear or the nerves connecting it to the brain [5]. If your cat was hearing fine yesterday and cannot hear today, treat it as urgent. Sudden hearing loss with balance signs is the pattern that worries veterinarians most. ## Red Flags That Make It an Emergency Call an emergency clinic now if your cat has any of these along with hearing loss: - A head tilt that started suddenly - Circling, falling, or rolling to one side - Eyes flicking back and forth - Vomiting or refusing to eat - Severe pain when you touch the head or ear - Bleeding or fluid from the ear - A recent head injury or fall - Known or suspected exposure to a toxin or a new medication These signs point to inner ear or brain involvement, not simple wax buildup. Inner ear disease can affect both hearing and balance because the same structures serve both jobs [5]. Call your veterinarian the same day if you see: - New discharge, odor, or swelling in the ear - Head shaking or scratching at one ear - A change in meowing volume or pitch - Your cat no longer waking to food or your voice ## Safe Things You Can Do at Home While you wait for your appointment, keep your cat safe and comfortable. - Approach from the front. Walk into your cat's field of view before touching them so you do not trigger a startle. - Use vibration and light. Stomp on the floor or flick the lights instead of shouting. - Keep the routine steady. Feed, play, and sleep at the same times. Deaf cats rely on routine. - Do not put anything in the ear canal. No cotton swabs, no home remedies, no ear drops unless your veterinarian prescribes them. - Keep your cat indoors. A deaf cat cannot hear traffic, dogs, or other dangers. - Tell other people in the home. Guests and children should know to approach slowly. - Watch for balance changes. If your cat starts tilting or wobbling, go to the vet right away. If your cat has a known ear infection and is being treated, follow the instructions exactly and finish the full course. Stopping early is a common reason infections come back and cause more damage. ## What Your Veterinarian Will Check Your veterinarian will start with a full history. They will ask when you first noticed the change, whether it was sudden or gradual, and whether your cat has had ear problems before. The physical exam focuses on the ears, head, and nervous system. Your vet will look into the ear canals with an otoscope to check for wax, discharge, polyps, or a ruptured eardrum. They will also check your cat's balance, eye movements, and facial nerves. ### Tests your vet may recommend - Otoscopy. A close look inside the ear canal. - Imaging. X-rays or CT can show middle ear disease, fluid, or polyps. - Brainstem auditory evoked response (BAER). This is the most reliable hearing test. It measures the brain's response to clicks delivered through small earphones. - Blood work. To look for infection, inflammation, or underlying disease. - Culture of ear discharge. To identify bacteria or yeast and pick the right treatment. Hearing testing is more reliable after kittens are 3 to 4 weeks old, when sound responses become predictable [2]. Cats deaf in only one ear are especially hard to diagnose without specialized testing [2]. ### What treatment looks like Treatment depends on the cause. Ear infections are treated with prescription medication, and your veterinarian will calculate the dose based on your cat's weight and health. Polyps are often removed. Wax and debris are cleaned out under sedation if needed. Many cats regain hearing once the blockage or infection is resolved [2]. If the deafness is permanent, your veterinarian will help you adjust your home and routine. There is no medication that restores hearing lost to aging or congenital causes. ## Preventing and Monitoring Hearing Loss You cannot prevent congenital deafness or aging changes. You can lower the risk from other causes. - Check ears weekly. Look for redness, odor, or discharge. Early treatment prevents damage. - Treat ear infections fully. Do not stop medication when your cat seems better. - Keep up with wellness visits. Senior cats should be seen at least once or twice a year. - Watch for subtle changes. Note when your cat stops responding to specific sounds. - Limit toxin exposure. Keep medications, cleaners, and plants out of reach. - Use caution with cotton swabs and home ear cleaning. Ask your vet before using any product. If your cat is deaf, they can still live a full, happy life indoors. Many deaf cats learn hand signals and adapt quickly. The main job is keeping them safe and catching any new problem early.

Only an exam and testing can do that. Individual cases need a veterinarian who can look at your cat, ask questions, and run the right tests. Contact your veterinarian the same day if your cat has new ear discharge, odor, head shaking, or a clear change in how they respond to sound. Go to an emergency clinic now if your cat has sudden hearing loss with a head tilt, circling, falling, eye flicking, vomiting, or a recent head injury. Schedule a routine visit if you have noticed a slow decline over months, especially in a cat over 10 years old. A baseline exam helps your vet track changes over time. ## Frequently Asked Questions ### Is deafness in cats common? Yes, hearing loss becomes more common with age, and sensory decline is described as nearly universal in aging cats and dogs [1]. Congenital deafness is less common overall but higher in certain white cats [3][6]. Many cases go unnoticed because cats adapt so well. ### Can a cat go deaf suddenly? Yes, sudden deafness can happen with inner ear disease, polyps, trauma, toxins, or certain drugs [2]. It often comes with balance problems because the inner ear controls both hearing and balance [5]. Sudden hearing loss should be treated as urgent. ### How can I tell if my cat is deaf or just ignoring me? Watch for a pattern. A cat with normal hearing still reacts to unexpected sounds when relaxed, while a deaf cat does not react even to loud noises nearby. A deaf cat also tends to watch your face and hands closely and may meow more loudly. If you are unsure, your veterinarian can test hearing. ### Do white cats with blue eyes always go deaf? No, the link is real but not absolute. White cats with blue eyes are more likely to be born deaf, but many hear normally [2]. In one group of white Devon Rex cats, blue eyes did not predict deafness at all [6]. ### Can hearing loss in cats be reversed? Sometimes. Hearing often returns when the cause is a blockage, wax, or an infection that can be treated [2]. Hearing lost to aging, congenital causes, or inner ear damage is usually permanent. Your veterinarian can tell you what to expect after the exam. ## Related Articles - [Symptoms Of Cat Ear Infection](/knowledge/veterinary-medicine/symptom-guides/symptoms-of-cat-ear-infection) - [Ear Infection Cats Symptoms](/knowledge/veterinary-medicine/symptom-guides/ear-infection-cats-symptoms) - [Cat Ear Infection: Signs and When to See a Vet](/knowledge/veterinary-medicine/vet-visit-decisions/cat-ear-infection-signs-when-to-see-vet) - [Cat Head Shaking and Ear Problems: What to Know](/knowledge/veterinary-medicine/skin-allergy-and-ear-care/cat-head-shaking-ear-problems) - [Ear Infections In Cats Symptoms](/knowledge/veterinary-medicine/symptom-guides/ear-infections-in-cats-symptoms) - [Symptoms Of Ear Mites In Cats](/knowledge/veterinary-medicine/parasitic-diseases/symptoms-of-ear-mites-in-cats) - [How to Tell If Your Cat Is Deaf or Hard of Hearing](/knowledge/veterinary-medicine/symptom-guides/cat-deafness-signs) - [Deafness in Older Cats: Causes and What to Expect](/knowledge/veterinary-medicine/senior-and-chronic-care/deafness-older-cats-causes) - [Congenital Deafness in Cats: Causes and Care](/knowledge/veterinary-medicine/symptom-guides/congenital-deafness-in-cats) ## References 1.
