Rabbit Care Guide for New Owners

Rabbits (Oryctolagus cuniculus) have become increasingly popular companion animals, but their complex medical and behavioural needs are often underestimated. As a veterinary surgeon, I have seen too many rabbits presented with preventable conditions such as dental disease, gastrointestinal stasis, and pododermatitis, problems rooted in inadequate husbandry. This pillar article provides an evidence-based, clinically grounded approach to rabbit care, covering housing, hay-based diet, litter training, neutering, health, and lifespan. Where possible, we integrate peer-reviewed literature and guidelines from authoritative bodies including the American Veterinary Medical Association (AVMA), the Rabbit Welfare Association & Fund (RWAF), the House Rabbit Society, and the Merck Veterinary Manual.

Quick Q&A

Housing

Proper housing is foundational to rabbit welfare. The RWAF and House Rabbit Society both emphasise that rabbits need a space large enough to perform natural behaviours: hopping, stretching, standing upright on hind legs, digging, and hiding. A commercial rabbit hutch is often insufficient unless attached to a secure, spacious exercise run.

Minimum space recommendations: The AVMA and European guidelines (FVE, EFSA) advise that a rabbit should be able to take three consecutive hops in any direction. For a pair of medium-sized rabbits (e.g., two 2.5 kg mixed-breed rabbits), the enclosure should measure at least 3 metres (10 feet) by 1.5 metres (5 feet) with a height of at least 60 cm (24 inches) to allow rearing.

Indoor vs. outdoor: In most climates, indoor housing is safer and promotes better health. Outdoor hutches expose rabbits to temperature extremes, predators, and insect-borne diseases such as myiasis (flystrike). If kept outdoors, the hutch must be placed in a shaded, sheltered area and brought inside during extreme weather. In Australia and parts of North America, rabbits should be protected from ticks: a study by Abdel-Shafy demonstrated that the cattle tick Rhipicephalus annulatus can feed on rabbits in laboratory conditions, though with reduced reproductive success [2]. While this particular tick is not a primary pathogen of rabbits, it underscores the risk of ectoparasites when housing rabbits near livestock or in grassy outdoor runs.

Bedding and substrate: Use paper-based bedding, aspen shavings, or hay. Avoid cedar or pine shavings: they emit volatile phenols that can cause respiratory and hepatic toxicity. Provide a separate litter tray, a hide box (preferably with two exits to prevent trapping), and a solid floor area to prevent pododermatitis (sore hocks). Wire-bottom cages are unacceptable and banned in several countries under animal welfare codes.

Environmental enrichment: Rabbits are intelligent and need mental stimulation. Provide cardboard tunnels, untreated wood chew sticks, and foraging opportunities (scatter hay or pellets in a puzzle feeder). Rotate toys to prevent habituation.

Hay-Based Diet

The cornerstone of rabbit nutrition is unlimited grass hay. The House Rabbit Society and the Merck Veterinary Manual state that hay should comprise approximately 80% of the daily diet by volume. Hay provides long-strand fibre which is essential for:

• Dental health: Rabbit teeth grow continuously (approximately 10–12 cm per year). The abrasive action of chewing hay grinds down the teeth and prevents malocclusion, a painful and often fatal condition requiring repeated veterinary dental filing.
• Gastrointestinal motility: Fibre stimulates peristalsis and prevents gut stasis, the most common emergency in pet rabbits. A lack of fibre leads to a slowed gastrointestinal transit time, allowing gas and toxin accumulation.
• Caecotrophy support: The fibre content ensures normal formation of caecotrophs (night faeces) which rabbits re-ingest for vitamin B and fatty acid absorption.

Hay types: Timothy hay is the gold standard for adult rabbits; meadow, orchard, and oat grass are also suitable. Alfalfa hay (legume) is too high in calcium and protein for adult rabbits and should be reserved for growing or lactating animals. In Europe and North America, check for mould or dust before feeding.

Pellets: A small quantity of high-fibre pellets (no seeds, grains, or coloured bits) can supplement the diet. The recommended amount is 1/8 to 1/4 cup per 2.5 kg body weight per day. Overfeeding pellets leads to obesity and caecal dysbiosis.

Vegetables: Include a daily variety of leafy greens (e.g., romaine lettuce, kale, cilantro, parsley). Introduce new vegetables one at a time to monitor for diarrhoea. Avoid starchy root vegetables (carrots, potatoes) as occasional treats only, due to high sugar content.

Water: Fresh water must be available at all times. Use a heavy ceramic bowl rather than a sipper bottle, as bowls encourage more natural drinking behaviour and reduce the risk of dehydration.

Litter Training

Litter training is both a convenience for owners and a tool for monitoring rabbit health. Rabbits are naturally clean animals that choose a specific corner to urinate and defecate. Training is straightforward when approached correctly.

Setup: Place a large litter tray in the rabbit's preferred elimination corner. Fill with a layer of paper-based cat litter (unscented, low-dust) and top with a generous layer of hay. Many rabbits eat hay while sitting in the tray, reinforcing the association.

Training process: Confine the rabbit to a small area (pen) for the first few days. Place hay and food near the litter tray. Reward the rabbit with a small treat when it uses the tray. Clean accidents with a 50/50 vinegar-water solution to remove odour cues. Never punish the rabbit: it creates fear and may worsen the behaviour.

Common problems: Urine spraying is most common in unneutered males (bucks). Castration dramatically reduces this behaviour. Inadequate tray size, dirty tray, or insufficient litter depth can also cause refusal. If a previously trained rabbit starts urinating outside the tray, rule out urinary tract infection or bladder sludge with a veterinary examination.

Health monitoring: The litter tray is a valuable diagnostic window. Normal rabbit urine ranges from pale yellow to deep orange (due to plant pigments) and may appear cloudy from calcium carbonate crystals (which is normal). Be concerned by red urine (haematuria) often indicating sludge or uterine adenocarcinoma, or by absent faeces (indicating gut stasis).

Neutering

Neutering (spaying in females, castration in males) is a critical preventative health intervention for rabbits not intended for breeding. The AVMA, AAHA, and RWAF all recommend early neutering, ideally at the onset of sexual maturity.

Spaying (ovariohysterectomy): Unspayed female rabbits (does) have an exceptionally high incidence of reproductive tract neoplasia. By age 4–5 years, up to 80% of does develop uterine adenocarcinoma, a highly metastatic and fatal cancer. Spaying at 4–6 months of age nearly eliminates this risk. Additional benefits include prevention of uterine infection (pyometra) and reduction of false pregnancy-related behavioural issues.

Castration (orchidectomy): Castration prevents testicular tumours (rare in rabbits but reported) and curbs undesirable behaviours such as urine spraying, mounting, and aggression. Castrated males also make better companions for other rabbits. The procedure can be performed once the testes have descended, usually around 10–12 weeks of age.

Anaesthetic considerations: Rabbits are high-risk anaesthetic patients. The American College of Veterinary Anesthesia and Analgesia (ACVAA) and European guidelines recommend pre-anaesthetic blood work, fasting of no more than 1–2 hours (to prevent hypoglycaemia and gut stasis), and a multimodal analgesic protocol. Use of injectable anaesthetics combined with isoflurane or sevoflurane is standard. An exotic-specialist veterinarian should perform the surgery, as rabbit anatomy differs significantly from cats and dogs.

Post-operative care: Monitor for signs of pain (teeth grinding, hunched posture, anorexia). Offer hay and water immediately after recovery. Provide a clean, quiet recovery space. Check the incision daily for swelling or discharge. Elizabethan collars are rarely needed in rabbits but can be used if necessary; stress should be minimised.

Health

Rabbits are prey species that mask illness effectively. By the time an owner notices lethargy or anorexia, the rabbit is often in critical condition. Regular health checks and preventative care are essential.

Common disease categories:

• Dental disease: Continuous tooth eruption predisposes rabbits to malocclusion, sharp enamel points (spurs), and abscesses. Signs include drooling, decreased appetite, and faecal pellet changes. Treatment involves veterinary burring under anaesthesia and dietary correction. Studies have investigated bone regeneration in rabbit mandibular defects: Isleyen et al. (2026) found that locally delivered dexpanthenol enhanced bone healing in a rabbit tibial defect model, with increased VEGF expression and osteoblast counts [1]. While this study is translational (not directly about dental disease), it highlights the relevance of rabbits as models for oral surgery and bone healing. For pet rabbit owners, maintaining normal occlusion through appropriate diet is the priority.

• Gastrointestinal stasis (ileus): The most common emergency. Causes include pain, stress, dehydration, and low-fibre diet. Clinical signs: reduced or absent faeces, abdominal bloat, anorexia, and tooth grinding (bruxism). Treatment includes fluid therapy, prokinetic drugs (e.g., metoclopramide, cisapride), probiotics, syringe feeding, and analgesia.

• Flystrike (myiasis): Particularly in outdoor rabbits or those with diarrhoea. Flies (e.g., Lucilia sericata) lay eggs on soiled fur; maggots hatch and burrow into skin, causing fatal toxaemia. Prevention: daily grooming, clean environment, prompt cleaning of soiled fur, insect repellents (e.g., permethrin licensed for rabbits in some countries). In warm months, check perineum twice daily.

• Respiratory disease: Pasteurella multocida causes snuffles (rhinitis, sinusitis, pneumonia). Vaccination is not available in all regions; in the UK, a pasteurellosis vaccine exists. Treatment requires long-term antibiotics (e.g., enrofloxacin, doxycycline) and supportive care. Isolate affected rabbits from others.

• Pododermatitis (sore hocks): Caused by pressure on rough, wet surfaces. Overweight rabbits are especially susceptible. Treatment involves weight reduction, soft bedding (deep hay, vet bed), and bandaging. Severe cases require surgery.

• Ectoparasites: Ear mites (Psoroptes cuniculi), fur mites (Cheyletiella parasitovorax), and fleas. As noted earlier, rabbits can serve as hosts for certain tick species [2], though this is more relevant in research or outdoor farming contexts. For pet rabbits, routine mite prevention (e.g., topical selamectin) and flea control are recommended, using products licensed for rabbits.

Vaccination: In regions where Rabbit Viral Haemorrhagic Disease (RVHD1 and 2) and Myxomatosis are endemic (UK, Europe, Australia), annual vaccination is essential. Consult local veterinary guidelines. In North America, Myxomatosis is less common but present in wild rabbits in some areas.

Annual check-up: The House Rabbit Society and RWAF recommend annual health exams for rabbits under 6 years and semi-annual exams for seniors. A thorough examination includes: body condition score, dental check with an otoscope or speculum, abdominal palpation, lung auscultation, coat and skin exam, and faecal analysis for coccidia and worm eggs.

Lifespan

Domestic rabbits, when provided with optimal care, have a median lifespan of 8 to 12 years. This represents a long-term commitment comparable to that of a dog. Factors that positively influence lifespan include:

• Neutering: Reduces reproductive cancers and behaviour-related stress.
• Hay-based diet: Prevents the two leading causes of death: dental disease and gut stasis.
• Indoor housing: Protects from trauma, extreme temperatures, and predators.
• Social housing: Rabbits are highly social; a bonded companion rabbit can reduce stress and increase activity. The EFSA guidelines on rabbit welfare highlight that solitary housing is detrimental.
• Preventative veterinary care: Early detection of age-related conditions (osteoarthritis, renal disease, thymoma) improves quality of life.

The oldest documented rabbit lived to 18 years. Achieving a long, healthy life requires dedication from the owner and collaboration with a veterinarian experienced in rabbit medicine. As with any companion animal, prevention is far more effective than treatment. By following the evidence-based recommendations in this guide, new rabbit owners can provide their pets with the welfare they deserve and enjoy many years of companionship.

Conclusion

Rabbits are not low-maintenance pets. Their physiology demands a permanent supply of hay, ample space for exercise, appropriate housing, neutering at the correct age, and lifelong veterinary oversight. This pillar article has synthesised clinical guidelines from the AVMA, RWAF, and House Rabbit Society with peer-reviewed evidence to create a comprehensive roadmap for new owners. By prioritising a hay-based diet, correct litter training, and preventative health measures, including neutering and routine veterinary check-ups, owners can dramatically improve their rabbit's welfare and lifespan. Remember, a well-cared-for rabbit is a rewarding companion that can live well into its second decade.
