Peripheral Neuropathy

Peripheral neuropathy in rabbits refers to damage or dysfunction of the peripheral nerves, which are the nerves outside the brain and spinal cord that transmit signals to and from the limbs, organs, and other parts of the body. Unlike central nervous system conditions that affect the brain or spinal cord, peripheral neuropathy specifically involves the network of nerves that extend throughout the body. This condition can affect sensory nerves that transmit sensations like touch and pain, motor nerves that control muscle movement, or autonomic nerves that regulate unconscious functions. Peripheral neuropathy is less commonly diagnosed in rabbits than in humans or dogs, partly because it is genuinely less common and partly because the subtle early signs are easily missed in prey animals that instinctively hide weakness.

The causes of peripheral neuropathy in rabbits are diverse and include metabolic disorders, toxic exposures, infectious diseases, trauma, and in some cases remain unknown or idiopathic. Metabolic causes include conditions affecting blood sugar regulation, kidney disease, and nutritional deficiencies. Toxic neuropathy can result from exposure to heavy metals, certain plants, or inappropriately administered medications. Infectious agents including certain bacteria and parasites can damage peripheral nerves. Direct trauma to nerves from injuries, compressions, or surgical complications may cause localized neuropathy. Understanding the underlying cause is essential for appropriate treatment and determining prognosis.

The impact of peripheral neuropathy on affected rabbits depends on which nerves are involved and the severity of damage. Sensory nerve involvement may cause numbness, abnormal sensations, or pain, leading to self-trauma of affected areas or failure to protect limbs from injury. Motor nerve damage results in weakness, muscle wasting, and impaired mobility. When multiple limbs are affected, the rabbit may have significant difficulty with normal locomotion. Autonomic nerve involvement, while harder to detect, can affect gut motility, bladder function, and other internal processes. Because affected rabbits may not feel their limbs normally or may be unable to move normally, they are at risk for secondary injuries, pressure sores, and may stop eating due to discomfort or difficulty accessing food, leading to the ever-dangerous GI stasis.

Treatment success varies considerably depending on the underlying cause of the neuropathy. Some causes, such as certain toxic exposures when caught early or nutritional deficiencies, may be fully reversible with appropriate intervention. Others, such as severe traumatic nerve damage or advanced metabolic disease, may cause permanent deficits. Early diagnosis and treatment offer the best chance for recovery, but this is challenging in rabbits who instinctively mask symptoms of illness and weakness. A rabbit-savvy veterinarian is essential for proper evaluation and management, as peripheral neuropathy in rabbits is relatively uncommon and requires expertise in both neurology and rabbit-specific medicine to diagnose and treat effectively.

Metabolic causes represent an important category of peripheral neuropathy in rabbits. Renal disease can lead to accumulation of uremic toxins that damage peripheral nerves over time, causing progressive weakness and sensory abnormalities. While true diabetes mellitus is rare in rabbits compared to cats and dogs, conditions affecting glucose metabolism can occur and potentially contribute to nerve damage. Hepatic disease affecting the liver's ability to process nutrients and clear toxins may indirectly impact nerve health. Electrolyte imbalances, particularly chronic hypocalcemia or disorders of phosphorus metabolism, can affect nerve function. These metabolic causes typically produce gradual onset of symptoms affecting multiple nerves, a pattern called polyneuropathy.

Nutritional deficiencies are an underrecognized cause of peripheral neuropathy in rabbits. Vitamin E deficiency causes degeneration of nerve tissues and muscle, a condition called white muscle disease or nutritional muscular dystrophy. Selenium deficiency often accompanies vitamin E deficiency and worsens the condition. B vitamin deficiencies, particularly thiamine (B1) and cobalamin (B12), can cause peripheral nerve damage. These deficiencies may occur in rabbits fed inappropriate diets lacking in fresh greens, those with malabsorptive conditions preventing nutrient uptake, or rabbits unable to properly practice cecotrophy and thus missing the B vitamins produced by gut bacteria. Fortunately, nutritional neuropathy is often reversible with appropriate supplementation and dietary correction.

Toxic exposures can cause acute or chronic peripheral neuropathy depending on the agent and exposure pattern. Lead toxicity from ingesting paint chips, old pipes, or contaminated materials causes neurological damage including peripheral nerve effects. Certain plants that rabbits might access, particularly if allowed to forage outdoors, can be neurotoxic. Inappropriately administered medications may have neurotoxic effects; for example, metronidazole at high doses or for prolonged periods can cause neurological toxicity. Some insecticides and pesticides to which rabbits might be exposed are neurotoxic. Environmental toxins including heavy metals contaminating water or soil can accumulate over time and damage nerves.

Infectious causes of peripheral neuropathy include certain pathogens that can affect nerve tissue. Encephalitozoon cuniculi, while primarily affecting the central nervous system, can potentially impact peripheral nerves as well. Bacterial infections that form abscesses near nerve pathways can cause compressive neuropathy. Borrelia burgdorferi, the bacterium causing Lyme disease, causes neuropathy in humans and other animals and theoretically could affect rabbits in endemic areas, though documentation is limited. Viral infections affecting nerves are possible but poorly documented in rabbits. Parasitic infections beyond E. cuniculi might contribute to neuropathy in some cases.

Traumatic causes produce focal or localized neuropathy affecting specific nerves. Direct injury to a nerve from fractures, crush injuries, or lacerations causes immediate dysfunction in the area served by that nerve. Surgical complications including nerve damage during orthopedic or other procedures can result in postoperative neuropathy. Compression of nerves by masses, abscesses, or spinal abnormalities like spondylosis causes gradual dysfunction as pressure accumulates. Repeated microtrauma, such as might occur with improper housing or excessive pressure on certain areas, can damage nerves over time. The mechanism of traumatic neuropathy involves physical disruption of nerve fibers, interrupting signal transmission. Depending on the severity of damage, function may recover as nerves heal or deficits may be permanent if the nerve is completely severed or severely damaged.

Early warning signs of peripheral neuropathy can be extremely subtle, particularly in rabbits who instinctively hide weakness as a survival mechanism. Owners may notice their rabbit moving somewhat differently, perhaps dragging a foot slightly, placing limbs in unusual positions, or seeming slightly uncoordinated. The rabbit might be more reluctant to exercise or play than usual. Subtle changes in posture, such as sitting with feet splayed unusually or shifting weight off certain limbs, can indicate discomfort or sensory abnormalities. Changes in grooming habits, particularly if the rabbit is neglecting certain areas, may reflect either an inability to reach those areas due to weakness or decreased sensation prompting less attention. Because these early signs are so subtle, peripheral neuropathy is often not recognized until more obvious symptoms develop.

Common symptoms of established peripheral neuropathy depend on whether sensory, motor, or both types of nerves are affected. Sensory neuropathy causes abnormal sensations or loss of sensation in affected areas. Rabbits may not respond normally to touch or may fail to withdraw from painful stimuli. They might hold affected limbs in abnormal positions because they cannot feel where the limb is in space, a deficit called proprioceptive loss. Conversely, some sensory neuropathies cause pain or abnormal unpleasant sensations, leading to overgrooming, self-mutilation, or reluctance to have affected areas touched. Motor neuropathy causes weakness in affected muscles, difficulty moving normally, and eventually muscle wasting as unused muscles atrophy.

Behavioral changes accompanying peripheral neuropathy reflect the rabbit's response to altered sensation and weakness. Activity levels typically decrease as the rabbit compensates for mobility difficulties. Appetite may decline if the rabbit has difficulty reaching food, if neuropathic pain reduces interest in eating, or if general malaise accompanies the underlying disease process. Any significant decrease in food intake puts rabbits at risk for GI stasis, a life-threatening emergency. Affected rabbits may become more withdrawn, spending more time sitting still rather than exploring. Some rabbits become irritable or bite when the affected areas are touched, particularly if neuropathic pain is present. Changes in litter box habits may occur if weakness affects the rabbit's ability to enter the box or assume appropriate posture.

Physical signs of peripheral neuropathy include observable weakness, abnormal limb positioning, and muscle wasting over time. The rabbit may knuckle over on affected feet, standing or walking on the tops of the paws rather than the soles. Dragging of limbs when moving is common. Muscle mass comparison between affected and unaffected limbs may reveal atrophy on the affected side. Skin changes in areas with sensory loss may include injuries the rabbit does not protect against, pressure sores from abnormal positioning, or lesions from self-trauma due to abnormal sensations. Reflexes may be diminished or absent on neurological examination. In cases involving autonomic nerves, signs might include gut motility changes, urinary issues, or difficulty regulating temperature.

Symptom progression in peripheral neuropathy varies based on the underlying cause. Toxic neuropathies may progress rapidly if exposure continues or may stabilize or improve once the toxin is removed. Metabolic neuropathies often progress gradually as the underlying disease advances but may improve with treatment of the primary condition. Traumatic nerve damage may recover gradually over weeks to months if the nerve was bruised but not severed, while severe injuries cause permanent deficits. Nutritional neuropathies typically improve within weeks of correcting the deficiency, though recovery may be incomplete if damage was severe. Monitoring symptom progression helps assess treatment effectiveness and adjust care plans.

Emergency symptoms related to peripheral neuropathy are less dramatic than those of central nervous system disease but still require prompt attention. Sudden loss of function in one or more limbs warrants immediate veterinary evaluation to rule out spinal cord compression or other urgent causes. Self-mutilation of affected limbs with open wounds requires intervention to prevent infection and manage pain. Signs of severe pain such as teeth grinding, hunched posture, or refusal to move should prompt urgent care. As with any condition affecting rabbits, not eating for 12 or more hours is an emergency requiring immediate attention regardless of the underlying cause. Progressive worsening despite treatment indicates the need for diagnostic reassessment.

Initial examination of a rabbit with suspected peripheral neuropathy begins with a comprehensive history and thorough physical examination by a rabbit-savvy veterinarian. The vet will ask about diet, environment, possible toxin exposures, the onset and progression of symptoms, and any concurrent health issues. A general physical examination assesses overall body condition, hydration, gut sounds, and organ systems. The neurological examination is particularly important and includes assessment of mental status, cranial nerve function, postural reactions, spinal reflexes, muscle tone, and response to stimuli. Differentiating peripheral neuropathy from central nervous system disease requires careful evaluation of the pattern of deficits. Finding a veterinarian experienced with rabbit neurology significantly improves diagnostic accuracy.

Diagnostic testing helps identify the underlying cause of peripheral neuropathy and rule out other conditions. Blood work including complete blood count and comprehensive chemistry panel evaluates for metabolic disease, organ dysfunction, and signs of infection or inflammation. Specific testing for blood glucose helps rule out diabetes-related neuropathy. Kidney function tests identify uremia that can cause neuropathy. Liver function tests assess hepatic disease. Testing for specific nutritional deficiencies may be available for certain vitamins and minerals. E. cuniculi serology is often performed to assess for this common rabbit pathogen that affects the nervous system. Radiographs may be taken to evaluate for spinal abnormalities, masses, or other structural causes.

Advanced diagnostics may be necessary when routine testing fails to reveal the cause or when characterizing the neuropathy is important for treatment planning. Electrodiagnostic studies including electromyography and nerve conduction studies can characterize the type and severity of nerve damage, though availability for rabbits is limited. CT or MRI imaging can identify masses, abscesses, or structural abnormalities compressing nerves. If toxicity is suspected, testing for specific toxins may be available. Nerve or muscle biopsy, while invasive, can provide definitive diagnosis of certain neuropathies and is occasionally performed when other diagnostics are inconclusive. Referral to a veterinary neurologist may be beneficial for complex cases.

Differential diagnosis for symptoms of peripheral neuropathy in rabbits includes conditions that may appear similar but have different causes and treatments. Spinal cord disease from spondylosis, disc disease, or trauma can cause limb weakness that might be confused with peripheral neuropathy but involves central rather than peripheral nerve dysfunction. Arthritis causes limb dysfunction from joint rather than nerve problems. Pododermatitis causes altered gait and reluctance to move but is a skin and soft tissue condition. Fractures cause localized lameness. Myopathy or muscle disease causes weakness that may mimic motor neuropathy. The neurological examination pattern helps differentiate these conditions, and additional testing confirms the diagnosis.

Treatment of peripheral neuropathy focuses primarily on addressing the underlying cause when it can be identified. For metabolic neuropathies, treating the primary condition is essential. Renal disease requires appropriate management including fluid support, dietary modification, and medications as indicated. Hepatic disease needs treatment tailored to its cause. Electrolyte imbalances require correction through appropriate supplementation. For nutritional neuropathies, supplementation with deficient nutrients and dietary correction form the cornerstone of treatment. Vitamin E and selenium supplementation addresses deficiency states. B vitamin supplementation may be beneficial. Addressing underlying GI disease that prevents nutrient absorption is important for lasting improvement.

Toxic neuropathies require identification and elimination of the toxic exposure. If lead toxicity is identified, chelation therapy may be recommended under veterinary guidance. Removing the rabbit from environments containing the toxic substance is essential. Supportive care during recovery allows time for nerves to heal once the toxic exposure stops. Drug-induced neuropathy requires discontinuation of the causative medication and substitution of alternatives if treatment for the original condition is still needed. Recovery from toxic neuropathy can take weeks to months and may not be complete depending on the extent of nerve damage.

Supportive care plays an important role regardless of the underlying cause. Pain management is essential if neuropathic pain is present; gabapentin is often used for neuropathic pain in animals and may be appropriate for rabbits under veterinary guidance. Anti-inflammatory medications like meloxicam may help reduce inflammation affecting nerves. Physical therapy including passive range of motion exercises helps maintain joint flexibility and may support nerve recovery. Preventing secondary injuries in rabbits with sensory loss requires environmental modifications. Nutritional support ensures adequate calorie and nutrient intake; syringe feeding with critical care formula may be necessary if the rabbit's eating is compromised. Gut motility support prevents GI stasis, which is a constant risk for rabbits who are eating less or experiencing stress from illness.

Specific treatments for certain causes of neuropathy may be indicated. For infectious causes, appropriate antimicrobial therapy addresses the underlying infection. If E. cuniculi is suspected, fenbendazole treatment is initiated. Bacterial infections require rabbit-safe antibiotics such as enrofloxacin or trimethoprim-sulfa; never use oral penicillin-type antibiotics, amoxicillin, clindamycin, or lincomycin as these are fatal to rabbits. For compression neuropathy from masses or abscesses, surgical intervention may be necessary if the structure can be safely removed or drained. Traumatic neuropathy may benefit from anti-inflammatory therapy during the acute phase to reduce swelling around the nerve.

Rehabilitation and physical therapy support recovery from peripheral neuropathy and help maintain function while healing occurs. Passive range of motion exercises keep joints flexible and may stimulate nerve regeneration. Massage therapy improves circulation to affected areas. Assisted standing and weight-bearing exercises maintain muscle mass and strength. Hydrotherapy, if available, provides low-impact exercise. Environmental modifications ensure the rabbit can access food, water, and litter without difficulty despite mobility impairment. Non-slip surfaces prevent falls and injuries. For rabbits with permanent deficits, adaptive devices might help maintain mobility and quality of life.

Treatment decisions should consider the likelihood of improvement, the underlying cause, the rabbit's quality of life, and practical factors including cost and owner ability to provide care. Some neuropathies respond well to treatment and resolve completely. Others stabilize with treatment but leave permanent deficits. Some progressive neuropathies may not respond to treatment and continue to worsen. Honest discussions with your veterinarian about expected outcomes help set realistic expectations. For rabbits with severe, painful, or progressive neuropathy that significantly impairs quality of life and is unlikely to improve, humane euthanasia may be the most compassionate option.

Recovery timeline for peripheral neuropathy varies enormously depending on the underlying cause and severity of nerve damage. Nutritional neuropathies may show improvement within days to weeks of starting appropriate supplementation, though complete recovery can take several weeks to months. Toxic neuropathies typically begin to improve after the toxic exposure is eliminated, with recovery occurring over weeks to months depending on the extent of damage. Metabolic neuropathies may stabilize or improve with treatment of the underlying condition, though recovery depends on how well the primary disease can be controlled. Traumatic neuropathies recover at the rate of nerve regeneration, approximately 1 to 2 millimeters per day, meaning full recovery of an injured nerve can take months.

Post-treatment care focuses on supporting recovery while managing any ongoing deficits. If the underlying cause required specific treatment such as chelation for lead toxicity or antimicrobial therapy for infection, those treatments must be completed as prescribed. Nutritional support continues to ensure adequate intake, with syringe feeding supplementation if the rabbit is not eating enough independently. Physical therapy exercises should continue throughout recovery to maintain joint flexibility and muscle mass. Protection from injury remains important for rabbits with sensory deficits who cannot feel to protect their limbs. Monitoring food intake and fecal output remains essential to catch any GI complications early.

Prognosis factors for peripheral neuropathy include the underlying cause, the severity and duration of nerve damage before treatment, and the specific nerves involved. Causes that can be fully corrected, such as nutritional deficiencies or reversible toxic exposures, carry better prognoses than causes that cannot be eliminated. Mild nerve damage typically recovers more completely than severe damage. Nerves that were compressed but not destroyed have better potential for recovery than those that were severely injured or severed. Younger rabbits may recover better than seniors. The rabbit's overall health and immune function affect healing capacity.

Long-term outlook depends on how much nerve function returns and whether the underlying cause is controllable. Some rabbits make complete recoveries with no lasting effects. Others improve but retain some degree of weakness, sensory abnormality, or other deficits. For conditions with controllable underlying causes, maintaining appropriate treatment prevents recurrence or progression. Conditions that cannot be cured may continue to cause gradual decline despite treatment. Rabbits with permanent deficits can often adapt and maintain good quality of life with appropriate environmental modifications and care. Regular veterinary monitoring helps track progress and catch any changes that require intervention.

Primary prevention of peripheral neuropathy focuses on avoiding known causes and maintaining optimal health. Proper nutrition is foundational; ensuring an appropriate diet with unlimited grass hay, limited quality pellets, and daily fresh leafy greens provides necessary vitamins and minerals. Vitamin E and selenium supplementation may be beneficial for rabbits at risk of deficiency. Allowing normal cecotrophy by ensuring the rabbit can access and consume cecotropes provides B vitamins and other nutrients essential for nerve health. Preventing access to toxic substances requires rabbit-proofing environments to eliminate lead paint, toxic plants, pesticides, and other hazardous materials.

Environmental prevention involves creating safe living conditions that protect against injury and toxic exposures. Housing should be free of sharp edges, points, or other hazards that could cause traumatic nerve injury. Proper flooring with adequate traction prevents falls. The environment should be free of toxic plants, whether houseplants within reach or outdoor plants if the rabbit has garden access. Pesticides, herbicides, and other chemicals should never be used in areas where rabbits live or exercise. Indoor housing generally provides better protection from environmental toxins than outdoor housing. Proper ventilation without drafts maintains air quality.

Dietary prevention ensures adequate nutrient intake to prevent nutritional neuropathy. Unlimited high-quality grass hay should form the majority of the diet. Fresh leafy greens provide vitamins and variety. Pellets should be high-quality and fed in appropriate amounts. Clean fresh water should always be available. Avoid feeding inappropriate foods that might interfere with nutrient absorption or gut health. If a rabbit has conditions affecting nutrient absorption, work with your veterinarian to ensure adequate nutrition through supplementation if needed. Maintain consistent feeding routines, as sudden dietary changes stress the digestive system.

Health maintenance through regular veterinary care helps identify and manage conditions that could lead to neuropathy. Annual or biannual wellness examinations with a rabbit-savvy veterinarian allow early detection of metabolic diseases, organ dysfunction, and other conditions that might eventually affect nerves. Blood work screening for organ function can identify kidney or liver disease before it advances enough to cause neurological complications. Maintaining a healthy weight and activity level supports overall health. Promptly addressing any health concerns rather than waiting prevents conditions from advancing to the point of causing complications like neuropathy.

Early intervention when any symptoms of peripheral neuropathy appear offers the best chance for recovery. Learn to recognize subtle signs of nerve dysfunction such as slightly altered gait, unusual limb positioning, or decreased sensation. Any changes in mobility or coordination warrant veterinary evaluation. If a specific cause like toxin exposure is identified, removing the rabbit from exposure immediately limits nerve damage. Addressing nutritional deficiencies promptly before severe nerve damage occurs improves outcomes. Working with your veterinarian at the first sign of problems rather than waiting to see if symptoms resolve maximizes the potential for full recovery.

Daily management of a rabbit with peripheral neuropathy requires attention to the specific deficits present and consistent monitoring. For rabbits with sensory loss, daily inspection of affected areas is essential to identify injuries the rabbit cannot feel. Check between toes, on the bottoms of feet, and on any areas that contact surfaces for pressure sores or wounds. For rabbits with motor weakness, ensure they can access food, water, and litter without difficulty. Monitor food intake carefully, weighing food bowls if needed to quantify consumption. Check litter box output daily to ensure normal fecal pellet production. Any decline in eating or fecal output warrants immediate attention given the risk of GI stasis.

Home environment modifications help rabbits with neuropathy live safely and comfortably. Provide excellent traction on all surfaces with materials like fleece, rubber mats, or textured surfaces that prevent slipping. Remove ramps, platforms, or other areas where falls could occur if the rabbit has balance or coordination deficits. Place food, water, hay, and litter at floor level in easily accessible locations. Use low-sided containers that do not require climbing or reaching. Provide soft, padded resting areas to prevent pressure sores, particularly for rabbits who cannot shift position normally. Keep the environment at comfortable temperatures since rabbits with autonomic neuropathy may have difficulty thermoregulating.

Quality of life for rabbits with peripheral neuropathy can be maintained with appropriate care, though the degree depends on the severity and type of deficits. Signs of good quality of life include maintaining appetite, producing normal fecal output, showing interest in surroundings, engaging in some normal behaviors, and appearing comfortable at rest. Rabbits with mild deficits may have near-normal quality of life with minor accommodations. Those with more significant deficits can still enjoy favorite treats, gentle interaction, and comfortable rest. Signs of poor quality of life include inability to eat or drink without assistance, persistent pain despite treatment, severe self-trauma of affected areas, obvious distress, or inability to rest comfortably. Quality of life should be assessed honestly and regularly.

Monitoring and ongoing care involves regular assessment of the rabbit's neurological status and overall health. Track whether symptoms are stable, improving, or worsening over time. Watch for signs of secondary problems such as pressure sores, muscle wasting, self-trauma, or GI issues. Weigh the rabbit weekly to monitor for weight changes that might indicate problems. Schedule regular veterinary rechecks to assess progress and adjust the care plan as needed. Keep a log of observations, including mobility, eating, fecal output, and any concerning signs, to share with your veterinarian.

Caregiver support matters because managing a rabbit with chronic neurological disease requires ongoing commitment. Connect with other rabbit owners through resources like the House Rabbit Society for practical advice and emotional support. Be realistic about the time and financial resources required for ongoing care. Ask for help from family or friends when needed, particularly for tasks like physical therapy exercises that benefit from consistency. Acknowledge the emotional challenges of caring for a pet with chronic illness. Work with a supportive veterinary team who understands both your rabbit's needs and your challenges. If quality of life cannot be maintained despite good care, know that humane euthanasia is a compassionate option that should be discussed with your veterinarian.

Peripheral neuropathy can affect rabbits of any breed, and no breed has specific documented predisposition to this condition. The condition is relatively uncommon overall in rabbits compared to some other species, and breed-specific data is extremely limited. However, certain breed characteristics may influence risk for conditions that can cause secondary neuropathy. Large and giant breeds such as Flemish Giants may be at increased risk for spondylosis and other spinal conditions that could compress nerves as they exit the spinal column. Dwarf breeds may be more prone to certain metabolic conditions. Lop breeds are predisposed to dental disease, which does not directly cause neuropathy but may affect overall health.

Risk factors for peripheral neuropathy relate more to individual circumstances than to breed. Senior rabbits of any breed are at increased risk for degenerative conditions and metabolic diseases that can cause neuropathy. Rabbits with chronic kidney or liver disease face risk from metabolic toxin accumulation. Those fed inappropriate diets lacking essential nutrients are at risk for nutritional neuropathy regardless of breed. Rabbits with access to potential toxins in their environment face exposure risk. Rabbits unable to practice cecotrophy due to obesity, arthritis, or other conditions may develop B vitamin deficiencies that affect nerves.

Screening recommendations apply broadly rather than to specific breeds given the lack of breed-specific predisposition data. All rabbits benefit from regular wellness examinations that can detect conditions potentially leading to neuropathy. Metabolic screening through blood work, particularly for senior rabbits, can identify kidney or liver issues early. Ensuring appropriate diet provides nutritional neuropathy prevention for all breeds. Rabbit-proofing environments to eliminate toxin exposure protects all rabbits. For rabbits diagnosed with conditions that could cause neuropathy, monitoring for early neurological signs allows prompt intervention.

Commonly co-occurring conditions with peripheral neuropathy often relate to the underlying causes. Kidney disease may cause neuropathy through uremic toxicity and often exists alongside other complications of renal dysfunction. Liver disease can cause or accompany neuropathy. Nutritional deficiencies causing neuropathy may also affect other organ systems. GI stasis is a dangerous secondary complication that can develop whenever a rabbit eats less than normal due to discomfort, weakness, or difficulty accessing food, making aggressive nutritional support essential for any rabbit with neuropathy. Pressure sores and skin injuries develop secondary to sensory loss and immobility if protective care is not provided.

Conditions with similar symptoms to peripheral neuropathy require differentiation for accurate diagnosis. Spinal cord disease from spondylosis, disc disease, or E. cuniculi causes limb weakness and sensory changes that may appear similar but involves central rather than peripheral nerve dysfunction. Arthritis causes limb dysfunction and reluctance to move that might be confused with weakness from neuropathy. Pododermatitis causes altered gait and discomfort that affects mobility. Myopathies or muscle diseases cause weakness that may mimic motor neuropathy. Vestibular disease causes balance problems that might be confused with weakness. The veterinarian differentiates these through careful neurological examination and appropriate diagnostic testing.

Potential complications of peripheral neuropathy include both direct consequences of nerve dysfunction and secondary problems from altered mobility and sensation. Self-trauma to areas with abnormal sensation can cause wounds and infections. Pressure sores develop over bony prominences in rabbits who cannot shift position normally or who cannot feel developing pressure damage. Muscle atrophy occurs in limbs whose motor nerves are affected, making recovery of function more difficult even if nerve function improves. Falls and injuries are more likely in rabbits with impaired coordination. Hepatic lipidosis can develop rapidly if the rabbit does not eat adequately, making nutritional support critical for preventing this life-threatening complication.
