Spinal Injury / Paralysis

Spinal injury in rabbits represents one of the most devastating emergencies, potentially resulting in permanent paralysis, loss of bladder and bowel control, and severe compromise to quality of life. The rabbit's skeletal structure makes them particularly vulnerable to spinal trauma, with a lightweight skeleton comprising only 7 to 8 percent of body weight compared to 13 percent in cats. This delicate bone structure, combined with the powerful hind leg muscles that generate tremendous force during kicking, creates conditions where improper handling, falls, or sudden violent movements can result in vertebral fracture or dislocation and subsequent spinal cord damage. Understanding the fragility of the rabbit spine is essential for all rabbit owners and anyone handling these animals.

Spinal injuries in rabbits most commonly occur in the lumbar region of the lower back, where the powerful kicking motion of the hind legs generates tremendous forces against the vertebral column. The most frequent scenario involves a rabbit kicking out forcefully while being held, particularly if the hindquarters are not properly supported, causing hyperextension and fracture or luxation of lumbar vertebrae. Other causes include falls from height, being dropped, being stepped on, predator attacks, improper picking up technique, and rarely, pathological fractures through bone weakened by disease such as spondylosis or bone tumors. Spontaneous fractures can occur in rabbits with severe underlying bone disease.

The consequences of spinal cord injury vary dramatically depending on the location and severity of damage. Injuries high in the cervical spine can be immediately fatal due to disruption of breathing control. Thoracic injuries may cause paralysis of the hind limbs while preserving front limb function. Lumbar injuries, the most common type, typically cause hind limb paralysis, loss of bladder and bowel control, and loss of sensation in the hindquarters. The severity of cord damage ranges from mild bruising causing temporary weakness to complete transection causing permanent, irreversible paralysis. Initial assessment cannot always predict final outcome, as spinal cord swelling that resolves may permit recovery that initially seemed impossible.

Treatment and prognosis for spinal injury depend on injury severity, location, and whether any voluntary movement or sensation remains. Some rabbits with incomplete cord injuries recover significant function with appropriate treatment including anti-inflammatory medications, strict cage rest, and time for healing. Others have permanent paralysis that may still permit good quality of life with dedicated nursing care, including manual bladder expression, mobility assistance, and specialized housing. However, complete spinal cord transection carries a grave prognosis, and humane euthanasia is often the kindest option for rabbits with complete, irreversible paralysis. Finding a rabbit-savvy veterinarian experienced with neurological cases is essential for accurate prognosis and treatment planning.

The primary cause of spinal injury in rabbits is traumatic force applied to the vertebral column, most commonly resulting from improper handling or restraint. When a rabbit kicks forcefully while being held without adequate support of the hindquarters, the powerful muscles of the hind legs generate force against the lumbar spine that can exceed the structural capacity of the delicate vertebrae. This scenario accounts for the majority of spinal injuries in pet rabbits and is entirely preventable with proper handling technique. The rabbit's natural flight response makes restraint inherently dangerous if the animal panics and attempts to escape through violent kicking. Falls from height, even relatively modest heights, can cause spinal injury if the rabbit lands awkwardly or attempts to twist during the fall.

Beyond acute trauma, underlying conditions can predispose rabbits to spinal injury. Spondylosis, a degenerative condition affecting the spine, causes bony changes that can compress the spinal cord or weaken vertebral integrity. Vertebral bone infections from hematogenous spread or extension of abscesses can weaken the spine. Spinal tumors, whether primary bone tumors or metastatic disease, compromise vertebral strength. Metabolic bone disease from nutritional deficiencies can weaken the entire skeleton. Encephalitozoon cuniculi can cause spinal lesions contributing to neurological dysfunction. These underlying conditions may cause progressive weakness and paralysis or may predispose to pathological fractures from minor trauma that would not injure a normal spine.

Environmental factors contributing to spinal injury risk include inappropriate housing and husbandry practices. Slippery flooring that causes legs to splay increases the risk of spinal injury during normal activity. Excessive height in enclosures allows dangerous falls. Wire flooring or other inappropriate surfaces can cause feet to become trapped, leading to injury during attempts to escape. Housing that does not provide adequate space for natural movement may cause stress and increase panic responses during handling. Inadequate supervision during exercise outside the enclosure allows access to dangerous areas. Multi-level housing without appropriate ramp design allows falls.

Specific risk factors for spinal injury include improper handling by inexperienced individuals, recent adoption or rescue situations where handling responses are unknown, underlying spondylosis particularly in older rabbits, giant breeds where the spine bears more weight, dwarf breeds with proportionally more delicate skeletal structures, history of previous spinal injury, bone disease from any cause, and pregnancy where extra weight stresses the spine. Young children handling rabbits without supervision represents a significant risk factor, as children may not understand proper support techniques and may panic if the rabbit struggles, leading to dropping or improper restraint.

The mechanism of spinal cord injury involves mechanical disruption of the delicate neural tissue within the vertebral canal. Vertebral fracture or luxation causes immediate physical damage through compression, stretching, or severing of the spinal cord. Secondary injury continues over hours to days as inflammation, hemorrhage, and cellular death expand the zone of damage. The spinal cord has very limited ability to regenerate, so injury to neural tissue is largely permanent. The severity of the initial mechanical injury and the extent of secondary damage determine final neurological outcome. This is why early intervention with anti-inflammatory treatment can potentially improve outcome by limiting secondary damage even when the initial injury cannot be reversed.

Early warning signs and the onset of spinal injury symptoms are typically sudden and dramatic rather than gradual. In traumatic cases, symptoms appear immediately following the causative event such as a fall, improper handling, or accident. The rabbit may cry out or vocalize at the moment of injury, though some rabbits are silent. Immediate behavior following spinal injury includes attempts to move that appear uncoordinated or unsuccessful, dragging of the hind limbs, or complete inability to move the rear half of the body. In cases of underlying disease causing progressive cord compression, symptoms may develop more gradually, with increasing weakness and incoordination over days to weeks before frank paralysis develops.

The most common symptoms of spinal injury involve the hind limbs and hindquarters, reflecting the typical lumbar location of injuries. Hind limb paralysis presents as complete inability to move the back legs voluntarily, with the limbs appearing limp and dragging behind the rabbit. Paresis, or partial paralysis, shows as weakness with some voluntary movement preserved but insufficient for normal locomotion. The rabbit may attempt to move using only the front legs, dragging the hindquarters. Loss of sensation in the hind limbs means the rabbit does not respond to pinching or other painful stimuli in the affected areas. Incontinence typically accompanies paralysis, with urine dribbling continuously and loss of bowel control.

Behavioral changes following spinal injury reflect both the physical disability and the associated pain and distress. The rabbit may show signs of pain including teeth grinding, hunched posture of the front body, and reluctance to be touched. Depression and withdrawal from normal activities occur as the rabbit cannot perform normal behaviors. Appetite typically decreases significantly, raising the risk of secondary GI stasis. Grooming becomes impossible for the hindquarters, leading to soiling of the fur with urine and feces. Some rabbits become aggressive or defensive when approached, particularly if they associate handling with the original injury. Others become unusually quiet and withdrawn.

Physical signs observable during examination provide critical information for diagnosis and prognosis. Observation of the rabbit attempting to move reveals whether any voluntary hind limb motion is present. The position of the hind limbs, whether held normally, extended backward, or tucked abnormally, may indicate the level of injury. Swelling or abnormal contour over the spine may be visible or palpable in cases of severe vertebral displacement. The bladder is typically distended and palpable as a large, firm mass in the lower abdomen because the paralyzed rabbit cannot urinate voluntarily. Muscle tone in the hind limbs may be increased, decreased, or absent depending on the nature of the cord injury. Response to pain testing, or lack thereof, helps assess the extent of sensory loss.

Symptom progression varies considerably depending on injury severity and whether treatment is instituted. With incomplete cord injuries, swelling reduction over days may allow improvement in function, sometimes dramatic. With complete transection, no recovery of function below the injury level is possible. Without appropriate management, secondary complications develop rapidly. Urine scalding of the skin causes severe dermatitis. Fecal impaction may occur if the rabbit cannot defecate normally. Pressure sores develop over bony prominences in recumbent rabbits. GI stasis from pain and stress compounds the crisis. Muscle atrophy of the paralyzed limbs progresses over time. These secondary complications significantly affect quality of life and may become life-threatening.

Emergency symptoms following suspected spinal injury require immediate veterinary evaluation. Any rabbit that suddenly cannot move the hind legs, is dragging the back half of the body, or has fallen or been handled roughly and is now behaving abnormally needs emergency care. The rabbit should be transported with minimal handling, supported on a flat surface to prevent further spinal movement. This is a situation where waiting to see if improvement occurs is not appropriate, as early intervention with anti-inflammatory medication may improve outcome, and assessment of injury severity is necessary for treatment planning and honest discussion of prognosis.

Initial examination of a rabbit with suspected spinal injury combines careful neurological assessment with measures to prevent further injury. The rabbit should be handled minimally and supported on a flat surface to avoid additional spinal movement. The veterinarian will observe the rabbit's posture, voluntary movement attempts, and response to stimuli before any hands-on examination. Neurological evaluation assesses voluntary motor function in all four limbs, reflexes, muscle tone, and response to painful stimuli. The presence of deep pain sensation, tested by firmly pinching a toe and watching for conscious recognition of the stimulus, is a critical prognostic indicator. Palpation of the spine searches for areas of pain, swelling, instability, or abnormal alignment while minimizing manipulation.

Diagnostic imaging is essential for characterizing spinal injuries. Radiographs of the spine are typically the first imaging performed, revealing vertebral fractures, luxations, or dislocations. Multiple views including lateral and ventrodorsal projections provide comprehensive evaluation. Radiographs also identify underlying bone disease such as spondylosis, bone tumors, or metabolic bone changes that may have predisposed to injury. In some cases, radiographs appear normal despite significant cord damage if soft tissue injury occurred without bony changes. Advanced imaging with CT or MRI, when available, provides far superior detail of both bony structures and the spinal cord itself, better characterizing injury severity and guiding treatment decisions.

Differential diagnosis for paralysis in rabbits includes conditions other than acute spinal trauma that can cause similar symptoms. Encephalitozoon cuniculi can cause hind limb weakness and paralysis through spinal cord lesions, typically with more gradual onset. Spondylosis causing progressive cord compression presents with gradual weakness rather than acute paralysis. Spinal tumors cause progressive neurological decline. Stroke or other vascular events in the central nervous system can cause sudden neurological deficits. Severe arthritis or musculoskeletal pain may cause reluctance to move that mimics weakness. Metabolic conditions including severe hypoglycemia can cause profound weakness. Accurate diagnosis is essential as treatment and prognosis differ significantly among these conditions.

Diagnosis confirmation of spinal injury relies on the combination of history suggesting trauma, neurological findings localizing to the spinal cord, and imaging demonstrating vertebral injury. The level of injury is determined by correlating clinical findings with imaging, as the neurological examination reveals which spinal segments are affected. Prognosis assessment considers multiple factors including whether deep pain sensation is preserved, the extent of voluntary motor function, the degree of cord compression visible on imaging, and the stability of the vertebral injury. This information is essential for honest discussion with owners about expected outcomes and helps guide treatment decisions.

Emergency treatment for spinal injury focuses on preventing further damage and reducing secondary injury from inflammation. The rabbit should be kept quiet and confined to prevent movement that could worsen vertebral instability. Anti-inflammatory medications, typically corticosteroids such as dexamethasone or methylprednisolone in the acute phase, aim to reduce spinal cord swelling and limit secondary damage. Pain management with rabbit-safe medications including meloxicam and opioids such as buprenorphine addresses the significant pain associated with spinal trauma. Supportive care including fluid therapy, temperature regulation, and nutritional support begins immediately. The bladder must be expressed manually if the rabbit cannot urinate, as bladder overdistension causes additional damage.

Medical management forms the core of treatment for most spinal injuries in rabbits. Strict cage rest with confinement to a small, padded enclosure prevents further injury and allows healing. The duration of cage rest varies but typically extends for four to eight weeks or longer. Anti-inflammatory therapy continues beyond the acute phase, often transitioning from corticosteroids to NSAIDs like meloxicam. Pain medication continues as needed based on signs of discomfort. Physical therapy including passive range of motion exercises for the affected limbs helps prevent joint contracture and muscle atrophy. Hydrotherapy may be beneficial in some cases. Acupuncture has been used as an adjunctive therapy with variable reported results.

Surgical intervention may be considered in specific circumstances, though surgery for rabbit spinal injuries is not commonly performed and requires specialized expertise. Surgery may be indicated when imaging shows severe cord compression that could be relieved, unstable vertebral injuries that cannot be managed conservatively, or progressive neurological deterioration despite medical management. Surgical options include decompression to relieve pressure on the spinal cord, stabilization of unstable vertebrae, and removal of bone fragments or disc material compressing the cord. Surgery carries significant risks in rabbits due to their sensitivity to anesthesia and the delicate nature of spinal surgery. The decision to pursue surgery requires careful consideration of expected outcomes, available surgical expertise, and overall prognosis.

Supportive care for rabbits with spinal injury requires intensive nursing regardless of whether recovery is expected. Bladder management is critical, with manual expression typically required three to four times daily for rabbits unable to urinate voluntarily. Technique must be learned from the veterinarian to avoid causing injury. Keeping the hindquarters clean and dry prevents urine scald and fecal dermatitis through frequent cleaning, barrier creams, and appropriate bedding. Positioning and padding prevent pressure sores over bony prominences. Nutritional support ensures adequate food intake, with syringe feeding if appetite is poor. GI function must be monitored closely, with support for motility if stasis develops. Physical therapy maintains joint mobility and muscle condition.

Alternative and complementary treatments may support recovery in appropriate cases. Acupuncture has been reported to help some rabbits with neurological conditions, though evidence specifically for acute spinal trauma is limited. Laser therapy may reduce inflammation and promote healing. Massage supports circulation and comfort. Hydrotherapy provides supported exercise for rabbits with some voluntary movement. Wheelchair or cart devices can restore mobility for rabbits with permanent hind limb paralysis who retain good front limb function and otherwise good quality of life. These devices allow the rabbit to move independently while the hindquarters are supported.

Treatment decisions for spinal injury must honestly address prognosis and quality of life. Rabbits with preserved deep pain sensation, some voluntary movement, and incomplete cord injuries have the best chance of meaningful recovery with appropriate treatment. Those with complete, irreversible spinal cord transection face permanent paralysis requiring lifelong intensive nursing care. While some dedicated owners successfully manage paralyzed rabbits with good quality of life using bladder expression, cleanliness protocols, and mobility aids, this requires significant commitment. In many cases of complete paralysis with no deep pain sensation, particularly when the rabbit shows signs of suffering or when lifelong intensive care is not feasible, humane euthanasia is the most compassionate choice. This difficult decision should be made thoughtfully with veterinary guidance.

Recovery timeline for spinal injury varies tremendously based on injury severity and location. Rabbits with incomplete cord injuries and preserved deep pain sensation may show improvement beginning within days to weeks, with continued recovery potentially extending over two to three months or longer. The most rapid improvement typically occurs in the first two to four weeks, but gradual gains can continue for months. Those with more severe injuries may stabilize without significant recovery. Rabbits with complete cord transection and absent deep pain sensation are not expected to recover function below the level of injury regardless of treatment duration. Early assessment provides some prognostic guidance, but individual variation means that outcomes cannot always be predicted with certainty.

Post-treatment care during recovery from spinal injury is intensive and requires dedicated owner commitment. Cage rest continues throughout the recovery period, with gradual expansion of space only when the rabbit demonstrates improved stability and mobility. Bladder expression continues until the rabbit can urinate voluntarily, which may never occur in some cases. Physical therapy exercises performed multiple times daily help maintain joint flexibility and muscle condition. Cleanliness protocols prevent skin complications. Monitoring for complications including urinary tract infections, pressure sores, and GI stasis continues throughout recovery. Medication administration follows the prescribed schedule. Follow-up veterinary visits assess progress and adjust treatment as needed.

Prognosis factors for recovery from spinal injury include several key elements. The presence of deep pain sensation is the single most important prognostic indicator, as rabbits with preserved deep pain have significantly better outcomes than those without. The presence of any voluntary motor function suggests incomplete cord damage and potential for recovery. The radiographic appearance of the injury matters, with displaced fractures and severe cord compression carrying worse prognosis. The timing of treatment initiation affects outcome, with earlier intervention potentially limiting secondary damage. Age and overall health influence healing capacity. Underlying bone disease affecting vertebral healing changes expectations.

Long-term outlook for spinal injury survivors ranges from excellent to permanently disabled, depending on recovery. Rabbits who regain full or near-full function may return to normal lives with few or no restrictions. Those with persistent weakness or mild deficits may function well with minor accommodations. Rabbits with permanent paralysis but good front limb function and otherwise good health can potentially achieve acceptable quality of life with mobility aids and dedicated nursing care, though this requires significant owner commitment. Ongoing monitoring for complications including urinary tract infections, skin problems, and secondary issues continues indefinitely. Regular veterinary assessment helps ensure quality of life remains acceptable and guides decisions if the situation changes.

Primary prevention of spinal injury centers on proper handling techniques that support the rabbit's entire body and prevent violent kicking. The correct method involves supporting both the front of the rabbit under the chest and the hindquarters under the rump simultaneously, keeping the spine in normal alignment. Never pick up a rabbit by the ears, scruff, or legs alone. When carrying a rabbit, keep them close to your body with hindquarters supported. Never allow unsupervised handling by children. If a rabbit struggles or attempts to kick while being held, do not fight the struggle but rather place the rabbit down safely immediately. Teaching proper handling to everyone who may interact with the rabbit prevents the most common cause of spinal injury.

Environmental prevention creates safe conditions that minimize trauma risk. Housing should not have excessive height that allows dangerous falls. Multi-level enclosures need secure, appropriately designed ramps rather than steep stairs or ledges. Flooring should provide good traction to prevent slipping. Wire flooring that allows feet to become trapped should be avoided. Exercise areas should be rabbit-proofed to prevent falls from furniture, stairs, or other heights. Supervision during out-of-enclosure time prevents accidents. Other pets, particularly dogs, should never be left unsupervised with rabbits as attacks can cause devastating injuries.

Dietary and health prevention supports bone strength and overall health. Adequate calcium and phosphorus in appropriate ratios maintains bone density. Unlimited hay provides essential nutrients and fiber. Appropriate vitamin D through diet or limited supervised sun exposure supports calcium metabolism. Avoiding obesity reduces stress on the skeletal system. Regular veterinary examination detects developing bone conditions such as spondylosis before they predispose to injury. Addressing dental disease prevents pain-related behaviors that might increase injury risk. Managing conditions like E. cuniculi reduces neurological damage that could be mistaken for or complicate spinal injury.

Regular monitoring enables early detection of conditions that could predispose to spinal injury or indicate early spinal problems. Annual or bi-annual veterinary examination including spinal palpation and gait assessment catches developing issues. Radiographic screening may be recommended for breeds prone to spondylosis or for senior rabbits. Owners should observe their rabbit's movement patterns regularly, noting any changes in gait, reluctance to jump, or apparent back discomfort. Any weakness, incoordination, or gait abnormality warrants prompt veterinary evaluation. Early detection of conditions like spondylosis allows management modifications to reduce fracture risk.

Early intervention when any neurological symptoms appear can improve outcomes. Any sudden onset of weakness, incoordination, or paralysis requires immediate veterinary evaluation. Gradual onset of gait abnormalities should be assessed promptly rather than attributed to normal aging. If a fall, drop, or rough handling incident occurs, even if the rabbit appears normal initially, close monitoring for the next 24 to 48 hours is warranted, with veterinary assessment if any concerns arise. Having emergency veterinary contact information readily available ensures rapid access to care if injury occurs.

Daily management for rabbits with spinal injury or permanent paralysis requires dedicated, consistent care protocols. Bladder expression for rabbits unable to urinate voluntarily must occur three to four times daily using technique taught by the veterinarian. The hindquarters must be kept clean and dry through frequent checking and cleaning, typically multiple times daily, with barrier cream applied to protect skin from urine scalding. Bedding must be absorbent, easily cleaned, and changed as often as needed to maintain dryness. Physical therapy exercises if prescribed should be performed consistently. Medication administration follows prescribed schedules. Monitoring for complications including urinary tract infections, pressure sores, and GI changes is part of daily routine.

The home environment for a paralyzed rabbit requires specific modifications. Housing should have a single level with no climbing required. Soft, padded, absorbent bedding throughout prevents pressure sores and provides comfort. The flooring should allow some grip for the front legs while being gentle on dragging hindquarters. Food and water should be easily accessible from a recumbent position if needed. The space should be easy to clean thoroughly given the soiling that occurs. Temperature should be maintained consistently as paralyzed rabbits may have difficulty regulating body temperature. For rabbits using wheelchairs, space must accommodate the device and allow free movement.

Maintaining quality of life for paralyzed rabbits involves careful assessment and attention to enrichment within their capabilities. Rabbits with good front limb function can often enjoy interaction, grooming, appropriate treats, and mental stimulation despite hind limb paralysis. Wheelchair devices can restore remarkable mobility for appropriate candidates. Social interaction with bonded partners may continue with supervision, though some dynamics may change. Signs of good quality of life include interest in food and surroundings, willingness to interact, normal grooming behaviors for accessible areas, and absence of apparent pain or distress. Signs of poor quality of life including persistent pain, recurrent infections, skin breakdown, or depression warrant reassessment of the care plan.

Ongoing monitoring and veterinary care are essential for paralyzed rabbits. Regular veterinary visits assess for complications and monitor overall health. Urinalysis screens for urinary tract infections, which are common in rabbits requiring bladder expression. Skin checks identify early pressure sores or urine scald before they become severe. Weight monitoring ensures adequate nutrition. Mobility assessment tracks any changes in function. Quality of life discussions should occur regularly with the veterinary team, with honest evaluation of whether the rabbit remains comfortable and content. Treatment plans may need adjustment over time as conditions change.

Caregiver support is crucial when managing a paralyzed rabbit, as this represents one of the most demanding long-term care situations in rabbit ownership. The time commitment is substantial, with multiple daily sessions required for bladder expression, cleaning, and care. Emotional toll includes both the demands of caregiving and the knowledge that the rabbit has permanent disability. Financial costs for supplies, veterinary care, and potentially mobility devices add up over time. Support from rabbit communities, both online and local, provides practical advice and emotional understanding from others who have managed similar situations. Respite care options, if available, prevent caregiver burnout. Recognizing that choosing euthanasia for a paralyzed rabbit can be a compassionate and appropriate decision helps owners facing this difficult choice.

Certain rabbit breeds face elevated risk for spinal injury due to their physical characteristics or predisposition to underlying conditions. Giant breeds including Flemish Giants, Giant Chinchillas, and French Lops carry more weight on their spines, potentially increasing stress on vertebral structures. These large rabbits are also more difficult to handle properly, increasing the risk of handling-related injuries. Dwarf breeds including Netherland Dwarfs, Holland Lops, and Dwarf Hotots have proportionally more delicate skeletal structures that may be more vulnerable to injury from equivalent forces. Lop breeds in general are reported to have higher rates of spinal problems, possibly related to their altered head carriage and spinal alignment.

Beyond specific breeds, certain populations face elevated risk based on other factors. Elderly rabbits of any breed commonly develop spondylosis, a degenerative condition that can predispose to spinal cord compression or pathological fractures. Rabbits with metabolic bone disease from nutritional deficiencies or kidney disease have weakened bones throughout the body including the spine. Those with E. cuniculi may have spinal lesions that complicate their neurological status. Rabbits who have experienced previous spinal trauma or have known spinal abnormalities face elevated risk for future problems. Obese rabbits place additional stress on spinal structures.

Screening and prevention recommendations vary based on risk factors. All rabbits benefit from proper handling education for owners and anyone who will interact with the rabbit. Giant breeds and any rabbit known to be difficult to handle should be managed with extra care and potentially handled less frequently. Senior rabbits, particularly those showing any stiffness or mobility changes, may benefit from spinal radiographs to assess for spondylosis and guide management modifications. Breeds predisposed to spinal issues should receive regular veterinary assessment including gait evaluation. Maintaining healthy weight reduces spinal stress. Avoiding any handling by inexperienced individuals, particularly children, protects all rabbits but especially those in higher-risk categories.

Several conditions commonly co-occur with spinal injury or cause similar symptoms requiring differentiation. GI stasis develops almost universally in rabbits with spinal injuries due to pain, stress, and reduced mobility, requiring concurrent prevention and management. Urinary tract infections frequently develop in paralyzed rabbits requiring bladder expression, as incomplete emptying and catheterization increase infection risk. Pressure sores develop over bony prominences in recumbent or paralyzed rabbits, requiring proactive prevention through padding and repositioning. Urine scald dermatitis affects the hindquarters of incontinent rabbits and requires diligent cleanliness and skin protection. Muscle atrophy progresses in paralyzed limbs over time.

Conditions that may cause similar paralysis symptoms require differentiation for appropriate treatment. Encephalitozoon cuniculi can cause hind limb weakness and paralysis through spinal cord lesions, typically with more gradual onset and sometimes associated with head tilt or other neurological signs. Spondylosis causes progressive spinal cord compression presenting as gradual weakness rather than acute paralysis. Spinal tumors cause progressive neurological decline with possible pain and other systemic signs. Intervertebral disc disease, while less common in rabbits than dogs, can cause acute cord compression. Severe arthritis or musculoskeletal pain may cause reluctance to move that mimics neurological weakness. Stroke or other vascular events can cause acute neurological deficits.

Complications of spinal injury and paralysis affect multiple body systems. Urinary complications include infections, bladder stones from chronic retention, and kidney damage from backpressure. Skin complications include pressure sores, urine scalding, and fecal dermatitis. Musculoskeletal complications include joint contractures and severe muscle wasting. GI complications include chronic stasis and cecal impaction. Respiratory complications can develop in rabbits with high spinal lesions. Chronic pain may persist even when other aspects are managed well. These complications can significantly impact quality of life and may ultimately determine whether continued care remains appropriate and humane.
