Ear Wax Buildup / Cerumen Impaction

Ear wax buildup, also known as cerumen impaction, is a common condition in domestic rabbits where excessive earwax accumulates in the external ear canal. This buildup occurs when the natural production of cerumen, the waxy substance that protects and lubricates the ear canal, exceeds the ear's ability to naturally expel it. While all rabbits produce ear wax as part of their normal ear health maintenance, certain breeds and individuals are more prone to problematic accumulation that can lead to discomfort and secondary complications.

The condition develops when cerumen production increases or when the ear canal's self-cleaning mechanism becomes impaired. In rabbits, ear wax serves important protective functions, trapping dust, debris, and microorganisms before they can reach the delicate structures of the inner ear. However, when this wax accumulates excessively, it can create a warm, moist environment that becomes an ideal breeding ground for bacteria and yeast. Lop-eared rabbits are particularly susceptible due to their unique ear anatomy, which restricts airflow and prevents normal wax migration out of the ear canal.

Untreated ear wax buildup can significantly impact a rabbit's quality of life and overall health. Rabbits rely heavily on their acute hearing for detecting potential threats, and impaired hearing due to cerumen impaction can cause stress and anxiety. Additionally, the buildup can cause itching, discomfort, and head shaking, which may progress to more serious conditions such as ear infections or even ear canal damage from excessive scratching. As with many rabbit health issues, the discomfort from ear problems can lead to reduced appetite and secondary gastrointestinal stasis, making early detection and treatment essential.

Fortunately, ear wax buildup is highly treatable when caught early and managed appropriately. Regular ear checks should be part of every rabbit owner's health monitoring routine, with particular attention paid to breeds predisposed to ear problems. Treatment typically involves gentle cleaning by a rabbit-savvy veterinarian and addressing any underlying causes. Because rabbits hide illness and discomfort as prey animals, owners should not wait for obvious signs of distress before having ears examined. A rabbit-savvy veterinarian can demonstrate proper ear examination techniques and establish an appropriate preventive care schedule.

The primary cause of ear wax buildup in rabbits is an imbalance between cerumen production and natural elimination. Under normal circumstances, the ear canal has a self-cleaning mechanism where old wax gradually migrates outward and is shed from the ear opening. When this balance is disrupted, whether through increased production, decreased elimination, or anatomical abnormalities, wax begins to accumulate. Environmental factors such as dusty bedding, high humidity, or poor ventilation can stimulate excess wax production as the ear attempts to protect itself from irritants.

Genetic and hereditary factors play a significant role in predisposing certain rabbits to ear wax problems. Lop-eared breeds have a genetic predisposition due to their ear conformation, where the folded ear flap restricts normal airflow and prevents the natural outward migration of cerumen. This inherited ear structure creates narrow, curved ear canals that trap wax more easily than the upright ears of other rabbit breeds. Dwarf breeds with smaller ear canals may also experience proportionally greater problems with wax accumulation due to the reduced space for wax movement.

Environmental and lifestyle factors significantly contribute to ear wax accumulation in rabbits. Dusty hay or bedding can increase ear wax production as the body attempts to trap and expel irritating particles. Poor cage hygiene, inadequate ventilation, and exposure to smoke or other airborne irritants stimulate the ear's protective mechanisms. Outdoor rabbits may be exposed to more environmental debris and allergens, while indoor rabbits in dry, heated environments may experience changes in wax consistency that affect natural elimination. Stress, which affects many aspects of rabbit health, can also alter cerumen production and consistency.

Several risk factors increase a rabbit's likelihood of developing problematic ear wax buildup. Age plays a role, with older rabbits often experiencing changes in wax production and reduced effectiveness of the ear's self-cleaning mechanism. Rabbits with existing ear problems, including previous infections or ear mite infestations, may have scarring or structural changes that impair wax elimination. Obesity can contribute to increased wax production, and rabbits with limited mobility may not engage in the normal head shaking and grooming behaviors that help distribute and eliminate ear wax. Additionally, underlying allergies or skin conditions can alter the composition and quantity of cerumen produced.

The mechanism by which ear wax buildup develops involves both physical and biochemical processes. Cerumen is produced by specialized glands in the outer portion of the ear canal, and its composition includes lipids, proteins, and antimicrobial compounds. When production exceeds elimination, wax begins to accumulate and can become compacted over time. In lop-eared rabbits, the horizontal orientation of the ear canal allows gravity to work against wax migration, causing it to settle deeper in the canal. As wax ages and dries, it can become harder and more difficult to remove naturally, creating a progressive cycle of accumulation that may eventually lead to complete obstruction of the ear canal.

Early warning signs of ear wax buildup in rabbits can be subtle and easily overlooked by owners unfamiliar with normal rabbit ear health. Initial indicators may include mild head shaking, occasional ear scratching with the hind feet, or a slight odor from the ears that differs from the rabbit's normal scent. Owners may notice their rabbit tilting their head slightly when resting or showing less interest in sounds that would normally attract their attention. Because rabbits instinctively hide signs of illness and discomfort, these early symptoms require careful observation to detect. Changes in ear position or a reluctance to have ears touched during normal handling can indicate developing discomfort.

Common symptoms of established ear wax buildup become more apparent as the condition progresses. Affected rabbits often display increased frequency of head shaking and may scratch at their ears more persistently. The outer ear may appear dirty or have visible waxy deposits near the ear opening, though the majority of buildup is typically deeper in the canal. Some rabbits develop a characteristic brown or yellow discharge that can be seen around the ear canal entrance. The ears may feel warmer than normal due to mild inflammation, and there may be a distinct waxy or musty odor emanating from the affected ears.

Behavioral changes associated with ear wax buildup reflect the discomfort and potential hearing impairment caused by the condition. Rabbits may become less responsive to sounds, appearing to ignore their owners' voices or not reacting to noises that previously caught their attention. Activity levels may decrease as rabbits feel generally unwell, and some individuals become more irritable or resistant to handling, particularly around the head and ears. Appetite changes can occur as discomfort from the ears radiates to the jaw and affects eating comfort. Owners should monitor litter box habits closely, as reduced eating due to any discomfort can quickly lead to dangerous gastrointestinal stasis in rabbits. Changes in cecotrope consumption may also occur if the rabbit is feeling unwell.

Physical signs visible during examination become more pronounced as ear wax accumulates. The ear canal may appear narrowed or completely occluded when viewed with an otoscope, and the wax may range in color from light yellow to dark brown depending on age and composition. The ear flap and surrounding skin may show signs of irritation from scratching, including hair loss, redness, or small wounds. In lop-eared rabbits, the ear canal opening may be difficult to visualize due to the natural fold of the ear, making professional examination essential. Coat condition may deteriorate if the rabbit is spending more time scratching and less time grooming normally.

Symptom progression follows a predictable pattern if ear wax buildup is left untreated. What begins as mild discomfort can progress to significant pain and inflammation as the wax compacts and presses against the sensitive ear canal lining. Secondary bacterial or yeast infections often develop in the warm, moist environment created by wax accumulation, leading to purulent discharge and increased odor. The rabbit may hold the affected ear lower than normal or develop a slight head tilt if the condition becomes severe. Chronic cases can lead to permanent changes in the ear canal structure and recurrent problems.

Emergency symptoms requiring immediate veterinary attention include severe head tilting, loss of balance, rolling, rapid eye movements (nystagmus), or complete loss of appetite. While these symptoms typically indicate progression to inner ear involvement rather than simple wax buildup, they can develop from untreated cerumen impaction. A rabbit that has not eaten for twelve hours or more requires emergency care, as gastrointestinal stasis can quickly become life-threatening. Open-mouth breathing is always a dire emergency in rabbits and requires immediate veterinary attention regardless of the suspected cause. Any signs of intense pain, including loud teeth grinding, a hunched posture, or pressing the head against surfaces, warrant urgent evaluation by a rabbit-savvy veterinarian.

Initial examination for suspected ear wax buildup begins with a thorough history and physical assessment by a rabbit-savvy veterinarian. The vet will ask about the rabbit's breed, age, housing conditions, diet, and any behavioral changes the owner has noticed. Physical examination includes observing the rabbit's head carriage, response to sounds, and overall demeanor before focusing on the ears themselves. The veterinarian will carefully examine the external ear, noting any discharge, odor, or signs of self-trauma from scratching. Finding a veterinarian experienced with rabbits is crucial, as the unique anatomy of rabbit ears, particularly in lop breeds, requires specialized knowledge for proper examination and treatment.

Diagnostic testing for ear wax buildup centers on otoscopic examination, which allows the veterinarian to visualize the ear canal and tympanic membrane. Using a specialized instrument with a light and magnifying lens, the vet can assess the amount and consistency of wax present, check for signs of infection, and evaluate the health of the ear canal lining. In rabbits with significant buildup, it may be necessary to gently remove some wax before a complete examination is possible. Cytology, which involves examining a sample of ear debris under a microscope, helps identify any secondary bacterial or yeast infections that may have developed. In some cases, culture and sensitivity testing may be recommended to identify specific pathogens and guide antibiotic selection.

Differential diagnosis is important because several conditions can mimic or accompany ear wax buildup in rabbits. Ear mites produce dark, crusty debris that can be mistaken for wax but typically causes more intense itching. Bacterial or yeast infections may be primary conditions or secondary to wax accumulation and require specific treatment. Allergies can cause increased wax production and ear inflammation. Foreign bodies in the ear canal, though less common, must be ruled out. In lop breeds, the veterinarian must also assess for ear canal stenosis, where the canal has become chronically narrowed due to repeated inflammation. Accurate diagnosis matters because treatment varies significantly depending on the underlying cause.

Diagnosis confirmation involves synthesizing findings from the physical examination, otoscopic evaluation, and any laboratory tests performed. The veterinarian will assess the severity of the buildup and determine whether secondary complications such as infection are present. In cases where inner ear involvement is suspected based on neurological signs, additional imaging such as skull radiographs or CT scan may be recommended, though this level of diagnostics is typically reserved for more complex cases. Once a definitive diagnosis is made, the veterinarian can develop an appropriate treatment plan and discuss ongoing management strategies to prevent recurrence. Regular follow-up examinations are often scheduled to monitor treatment progress and adjust the care plan as needed.

Emergency and immediate treatment for ear wax buildup focuses on providing comfort and preventing complications while addressing the accumulation. If the rabbit shows signs of pain or has stopped eating due to discomfort, pain management with rabbit-safe medications such as meloxicam becomes a priority. Syringe feeding with critical care formula may be necessary if appetite is reduced, as maintaining gut motility is essential in rabbits. Hydration support through subcutaneous fluids may be provided if the rabbit is dehydrated. The veterinarian will perform an initial assessment to determine the severity of the condition and check for secondary infections that require immediate treatment.

Medical management of ear wax buildup involves the use of ceruminolytic agents, which are specialized ear drops designed to soften and dissolve accumulated wax. Only products specifically approved for use in rabbits or those prescribed by a rabbit-savvy veterinarian should be used, as many over-the-counter ear products contain ingredients that are irritating or toxic to rabbits. The softened wax is then gently removed through irrigation or manual extraction using specialized instruments. This process often requires multiple treatment sessions, particularly in cases of severe impaction. If secondary bacterial or yeast infection is present, appropriate antimicrobial ear drops will be prescribed. Oral antibiotics may be necessary for more serious infections, with rabbit-safe options including enrofloxacin or trimethoprim-sulfa, never penicillin-based antibiotics which are fatal to rabbits when given orally.

Surgical options are rarely necessary for simple ear wax buildup but may be considered in severe or chronic cases. Total ear canal ablation, a procedure that removes the entire ear canal, is a last-resort option for cases where chronic disease has caused irreversible damage and ongoing pain. This surgery is complex in rabbits and requires a highly experienced exotic animal surgeon. Rabbits require special anesthesia protocols different from those used in cats and dogs, and they must not be fasted before surgery as they cannot vomit. Any surgical procedure in rabbits carries additional risks and requires careful consideration of the potential benefits versus risks.

Supportive care during treatment is essential for successful outcomes in rabbits with ear wax buildup. Pain management should continue throughout the treatment period, as ear cleaning can be uncomfortable even with the gentlest techniques. Maintaining appetite is critical, so offering favorite foods and ensuring the rabbit continues eating their normal diet of unlimited hay, fresh greens, and appropriate pellets helps prevent secondary gastrointestinal stasis. A quiet, stress-free environment supports recovery, and the rabbit should be housed in a clean area with dust-free bedding to minimize further irritation. Gentle handling and minimizing stress during home treatments help maintain the rabbit's overall wellbeing.

Alternative and complementary treatments may support healing but should not replace conventional veterinary care. Warm compresses applied to the base of the ear may provide comfort and help soften wax for easier removal during cleaning sessions. Environmental modifications such as switching to dust-free bedding, improving ventilation, and reducing potential allergens can address contributing factors. Regular gentle grooming helps reduce overall debris that might enter the ears. Some owners find that maintaining optimal humidity levels in the rabbit's environment helps prevent wax from becoming excessively dry and impacted.

Treatment decision factors include the severity of the buildup, presence of secondary infections, the rabbit's temperament and tolerance for handling, and the owner's ability to provide home care. Cost considerations are relevant, as exotic veterinary care can be more expensive than care for cats and dogs, and multiple treatment sessions may be required for severe cases. Some rabbits tolerate ear cleaning well while others become extremely stressed, influencing whether treatments can be performed at home or must be done at the veterinary clinic. Quality of life must be considered in chronic cases, ensuring that treatment itself does not cause more distress than the condition. The goal is always to resolve the current buildup while implementing preventive measures to minimize future occurrences.

Recovery timeline for ear wax buildup varies depending on the severity of the condition and whether secondary complications were present. Mild cases may resolve within one to two weeks of treatment, while more severe impactions with secondary infections may require four to six weeks of ongoing management. During the first few days of treatment, owners should expect to see gradual improvement in comfort levels, with reduced head shaking and scratching. Appetite and fecal output should normalize quickly once pain is managed; any continued reduction in eating should be reported to the veterinarian immediately. Complete resolution of wax accumulation typically occurs over multiple cleaning sessions rather than a single treatment.

Post-treatment care focuses on maintaining ear health and preventing recurrence while monitoring for any signs of complications. Owners should follow the veterinarian's instructions for any prescribed ear medications, typically applied once or twice daily for a specified period. Unlike cats and dogs, rabbits often resist ear drops, so gentle restraint techniques demonstrated by the veterinary team help minimize stress during treatment. Activity should not be restricted, as normal movement and behavior help maintain overall health. Follow-up appointments are typically scheduled one to two weeks after initial treatment to assess progress and determine whether additional cleaning is needed.

Prognosis factors for ear wax buildup are generally favorable when the condition is caught early and treated appropriately. The best outcomes occur in rabbits whose owners implement preventive measures after treatment to reduce recurrence risk. Factors that improve prognosis include identifying and addressing underlying causes, consistent preventive care, and prompt treatment of any recurrence. More guarded prognoses apply to rabbits with anatomical abnormalities that predispose them to chronic problems, those with concurrent health issues affecting ear health, or cases where significant ear canal damage occurred before treatment. Early intervention consistently produces better outcomes than waiting until the condition becomes severe.

Long-term outlook for rabbits treated for ear wax buildup is generally excellent with appropriate ongoing management. Many rabbits require periodic ear cleaning as part of their regular health maintenance, particularly lop breeds with predisposing anatomy. Recurrence is common if underlying risk factors are not addressed, but with proper preventive care, episodes can be minimized and quickly managed when they do occur. Quality of life remains good for most rabbits, with normal hearing and comfort maintained through regular monitoring and care. Owners should establish a routine of weekly ear checks at home and schedule regular veterinary examinations to catch any accumulation before it becomes problematic.

Primary prevention of ear wax buildup begins with understanding your rabbit's individual risk factors and implementing appropriate monitoring. Owners of lop-eared breeds should be particularly vigilant, with weekly ear checks becoming part of their regular care routine. Learning what your rabbit's normal ears look like helps identify early changes that warrant veterinary attention. For breeds at higher risk, establishing a relationship with a rabbit-savvy veterinarian who can provide guidance on preventive ear care is essential. Some veterinarians recommend routine ear cleaning for predisposed breeds, while others prefer to clean only when accumulation is noted to avoid disrupting the ear's natural protective mechanisms.

Environmental prevention focuses on minimizing factors that contribute to excess wax production. Housing should have adequate ventilation without drafts, maintaining good air quality that reduces irritants reaching the ears. Bedding choice matters significantly; paper-based, hay, or other dust-free options are preferable to dusty wood shavings that can increase ear wax production. Regular cage cleaning prevents ammonia buildup from urine, which can irritate respiratory passages and ears. Indoor housing is generally recommended as it provides better environmental control and reduces exposure to outdoor allergens and debris. Temperature and humidity should be maintained at comfortable levels, as extremes can affect wax consistency.

Dietary prevention supports overall health, which influences ear wax production and the rabbit's ability to maintain ear health. Unlimited grass hay, comprising at least eighty percent of the diet, provides essential fiber for gastrointestinal health and promotes natural chewing behaviors that support overall wellbeing. A balanced diet with appropriate fresh leafy greens and limited high-quality pellets maintains optimal body condition. Obesity can contribute to various health problems including altered skin and ear conditions, so maintaining healthy weight through proper diet and exercise is important. Fresh, clean water should always be available. Consistent feeding routines prevent the stress of dietary changes, which can affect overall health.

Health maintenance through regular veterinary care is fundamental to preventing ear problems. Annual or semi-annual wellness examinations with a rabbit-savvy veterinarian should include ear assessment as part of the comprehensive physical exam. Rabbits in high-risk categories may benefit from more frequent check-ups. Parasite prevention reduces the risk of ear mites, which can cause changes in the ear canal that predispose to wax accumulation. Regular grooming, particularly for long-haired breeds, prevents loose fur from entering the ear canals. Nail trimming reduces the risk of ear trauma from scratching, and maintaining overall health through proper husbandry supports the ear's natural defense mechanisms.

Early intervention strategies help catch developing problems before they become serious. Daily observation of your rabbit's behavior can identify subtle changes such as increased head shaking or ear scratching that warrant closer examination. Learning to perform gentle home ear examinations, with proper technique demonstrated by your veterinarian, allows early detection of accumulation. Knowing your rabbit's normal behavior patterns helps identify when something is amiss, remembering that rabbits instinctively hide signs of illness. Keeping a health log can help track any patterns in ear problems. Prompt veterinary consultation at the first sign of ear abnormalities prevents minor accumulation from progressing to impaction and secondary complications.

Daily management of rabbits prone to ear wax buildup incorporates regular monitoring into the normal care routine. Each day, owners should observe their rabbit's ear position, head carriage, and any scratching or head-shaking behaviors. During regular handling and bonding time, a brief visual check of the ear openings can catch early signs of accumulation. Any prescribed or recommended ear cleaning should be performed according to the veterinarian's schedule, typically ranging from weekly to monthly depending on individual needs. Medication administration in rabbits can be challenging, so developing positive associations with handling through treats and gentle practice makes necessary ear treatments less stressful. Monitoring food and water intake daily helps detect any appetite changes that might indicate ear discomfort affecting overall wellbeing.

Home environment modifications support ear health and reduce factors that contribute to wax accumulation. The living space should be well-ventilated but draft-free, with clean air that minimizes dust and allergens. Bedding material should be changed frequently, using dust-free options such as paper-based products, hay, or fleece liners rather than wood shavings that create airborne particles. The environment should be kept at comfortable temperatures between sixty and seventy degrees Fahrenheit, as rabbits are sensitive to heat and temperature extremes can affect ear health. Humidity levels should be moderate, not excessively dry which can affect wax consistency, nor overly humid which promotes microbial growth. A quiet, low-stress location away from loud noises and household commotion supports overall health.

Quality of life for rabbits with ear wax predisposition remains excellent with proper management. These rabbits can enjoy all normal rabbit activities, including exercise, exploration, and social interaction. Mental stimulation through toys, tunnels, and environmental enrichment keeps rabbits engaged and active. Social needs remain important; bonded pairs provide companionship and mutual grooming that supports wellbeing, though grooming partners cannot clean inside each other's ear canals. Human interaction and daily bonding time are essential for domestic rabbits. Owners should watch for signs of good quality of life, including normal eating and drinking, active behavior, curiosity about surroundings, and comfortable resting postures.

Monitoring and ongoing care establish patterns that help maintain ear health long-term. Owners should know when to contact the veterinarian, including any signs of infection such as discharge, odor, or increased head shaking, as well as any changes in appetite or behavior. Regular check-up schedules should be maintained, with more frequent visits for rabbits with recurring issues. Keeping a simple log of ear cleaning dates, any noted accumulation, and changes in behavior helps identify patterns and informs veterinary discussions. Weight monitoring at home using a kitchen or postal scale helps track overall health, as weight loss can indicate developing problems. Daily checks of food intake and litter box output remain important for catching any developing gastrointestinal issues early.

Caregiver support resources help owners manage the ongoing needs of rabbits prone to ear problems. The House Rabbit Society provides extensive educational resources on rabbit care and health management. Local rabbit rescue organizations often offer advice and community support. Online communities dedicated to rabbit care can provide encouragement and practical tips from other owners managing similar conditions. Financial considerations are important to address, as ongoing veterinary care for exotic pets can be costly; pet insurance for rabbits or dedicated savings can help manage expenses. Managing a rabbit with chronic health needs can be demanding, so caregivers should acknowledge their own needs and seek support when feeling overwhelmed.

High-risk breeds for ear wax buildup are predominantly lop-eared rabbits, whose distinctive folded ears create anatomical conditions that promote wax accumulation. The Holland Lop, one of the most popular pet rabbit breeds, is frequently affected due to its compact ear canals and heavy ear leather that restricts airflow. English Lops, with their dramatically long ears that can span over twenty inches, face unique challenges as their ear canals have an extended horizontal component that impairs natural wax migration. French Lops and Mini Lops share similar predispositions. The underlying reason for increased risk in all lop breeds is the same: the folded ear structure creates a warm, humid environment with restricted air circulation where wax accumulates rather than being naturally expelled. These breeds may require routine ear cleaning throughout their lives as a preventive measure.

Moderate-risk breeds include those with smaller ear canals or other predisposing factors. Netherland Dwarfs and other dwarf breeds have proportionally smaller ear canals where even normal amounts of wax can cause relative obstruction. Polish rabbits and Britannia Petites may face similar size-related issues. Rex and Mini Rex breeds, while having upright ears, sometimes experience skin and coat variations that can affect ear health. Mixed breed rabbits with lop heritage may inherit ear conformation that increases their risk, even if they don't have fully lopped ears. As rabbits age, wax production and elimination patterns may change, putting older rabbits of any breed at increased risk.

Screening recommendations for at-risk breeds emphasize early and regular veterinary evaluation. Lop breeds should have their ears examined at every veterinary visit, with many practitioners recommending examination every six months even in apparently healthy rabbits. Owners acquiring lop-eared rabbits should discuss ear care expectations with a rabbit-savvy veterinarian early in the rabbit's life to establish baseline ear health and learn proper home monitoring techniques. When adopting rabbits with unknown histories, a thorough initial ear examination helps identify any existing conditions and establishes monitoring protocols. Breeders of lop varieties should educate new owners about ear care requirements specific to these breeds. Working with rabbit rescues that provide health assessments helps ensure adopters understand any special care needs their new companion may have.

Commonly co-occurring conditions with ear wax buildup include otitis externa, or outer ear infection, which frequently develops as a secondary complication of cerumen impaction. The warm, moist environment created by accumulated wax provides ideal conditions for bacterial and yeast overgrowth. Rabbits with chronic ear wax problems may also experience dermatitis around the ear opening from scratching and irritation. Dental disease, extremely common in rabbits, can cause changes in jaw position that affect ear canal structure and drainage. Any condition that causes reduced appetite, including ear discomfort, can lead to gastrointestinal stasis, making monitoring of eating and fecal output essential whenever ear problems are present. Stress from chronic ear discomfort can affect immune function and overall health.

Conditions with similar symptoms require careful differentiation to ensure appropriate treatment. Ear mites produce dark, crusty debris that can resemble wax but causes more intense itching and is caused by parasitic infestation requiring specific antiparasitic treatment. Bacterial ear infections may cause discharge and head shaking similar to wax buildup but require antibiotic therapy. Foreign bodies in the ear canal can cause sudden onset of head shaking and ear discomfort. Allergies affecting the ears may produce increased wax production along with inflammation. Ear canal tumors, though uncommon, can cause obstruction and discharge. Accurate diagnosis through veterinary examination is essential because treatment approaches differ significantly between these conditions.

Potential complications from untreated or chronic ear wax buildup can significantly impact rabbit health. Progression to otitis media, or middle ear infection, occurs when bacteria penetrate past the ear drum. Otitis interna, or inner ear infection, can develop and cause vestibular disease with head tilt, loss of balance, and nystagmus. Chronic inflammation can lead to ear canal stenosis, where scarring narrows the canal and creates a cycle of worsening accumulation. Hearing loss may occur from prolonged obstruction or damage to ear structures. Secondary gastrointestinal stasis can develop if ear discomfort reduces appetite, as even brief periods of not eating can trigger this life-threatening condition in rabbits. Hepatic lipidosis may develop in rabbits that stop eating, adding another layer of medical complexity. Prevention of complications relies on early recognition and appropriate treatment of ear wax buildup before secondary problems develop.
