Rabbits often hide pain and illness, so a small change from your rabbit’s normal routine can matter. This guide explains the warning signs owners can observe, the common categories of rabbit health problems, and when to contact a rabbit-savvy veterinarian. It is not a diagnosis guide: the same sign can have several causes, and some conditions that look similar require very different treatment.
Rabbit emergency signs: when to call a vet now
Contact a rabbit-savvy veterinarian or emergency clinic promptly if your rabbit has any of the following signs. Do not wait for every sign on the list to appear.
- Stopped eating, is eating much less than usual, or refuses favorite foods—especially with fewer or no droppings.
- Difficulty breathing, open-mouth breathing, blue or very pale gums, or obvious respiratory distress.
- Collapse, extreme weakness, unresponsiveness, seizures, or an inability to stand.
- A sudden head tilt, rolling, loss of balance, or uncontrolled eye movements.
- A swollen, hard, or very painful abdomen.
- Profuse watery diarrhea, marked dehydration, or a heavily soiled bottom with lethargy.
- Maggots or fly eggs on the rabbit, severe bleeding, a major wound, or significant trauma.
- Repeated straining to urinate, little or no urine, or obvious pain while urinating.
A rabbit that stops eating can deteriorate quickly. See our focused guide on what to do when a rabbit is not eating, but contact a veterinarian rather than relying on an article during an emergency.
Know your rabbit’s normal
The most useful health check is a comparison with your own rabbit’s usual behavior. Spend a minute each day checking the following:
- Appetite: Are they eating hay and approaching food with their usual interest?
- Droppings: Are the amount, size, and shape close to normal for this rabbit?
- Water and urine: Are they drinking and urinating normally, without straining?
- Movement and posture: Are they walking, resting, and interacting normally? A persistent hunched posture can be a sign of pain.
- Breathing, eyes, and nose: Is breathing quiet and easy? Are the eyes and nose free of new discharge?
- Face, mouth, coat, feet, and bottom: Look for drool, swelling, bald or sore areas, dirty fur, wounds, or parasites.
Regular weighing can reveal gradual weight loss that is easy to miss by sight. Use the same scale and method each time, record the result, and discuss a meaningful or continuing change with your veterinarian.
Common rabbit health problems and warning signs
Dental disease
Rabbit teeth grow continuously. Dental disease can involve the incisors, the cheek teeth, or the roots below the gumline. Warning signs may include eating more slowly, choosing soft foods, dropping food, reduced hay intake, drooling, a wet chin, facial swelling, eye discharge, weight loss, or smaller droppings.
A rabbit can still appear interested in food while being unable to chew comfortably. A complete dental assessment may require specialized examination and imaging, so visible front teeth alone do not rule dental disease in or out.
Reduced gut movement, GI stasis, and obstruction
Reduced appetite and reduced droppings are important warning signs, but “GI stasis” is not always the original cause. Dental pain, another illness, stress, dehydration, an unsuitable diet, or an intestinal obstruction can all affect gut movement. An obstruction and non-obstructive slowdown may look similar at home, yet they do not have the same treatment.
Seek veterinary advice promptly if appetite or droppings decrease, and urgently if the rabbit stops eating, produces no droppings, becomes weak, or develops abdominal swelling or pain. Fur found in the stomach is not automatically the primary problem; rabbits swallow fur while grooming, and poor gut movement can allow it to accumulate.
Respiratory, eye, and nasal problems
Repeated sneezing, nasal discharge, noisy breathing, watery or sticky eyes, matted front paws, low energy, or reduced appetite deserve veterinary assessment. Dental disease and blocked tear ducts can also contribute to eye or nasal signs, so symptoms should not automatically be labeled “snuffles.”
Labored breathing and open-mouth breathing are emergencies. Keep handling and transport as calm as possible while arranging immediate care.
Head tilt and other neurological signs
A head tilt, circling, rolling, tremors, weakness, seizures, or loss of balance can be caused by inner-ear disease, neurological disease, trauma, toxins, or other conditions. These signs do not confirm E. cuniculi by themselves. Prompt examination is important both to identify the likely cause and to provide supportive care.
Skin, coat, parasites, and flystrike
Hair loss, dandruff, intense itching, crusts, wounds, redness, or a dirty bottom may be associated with mites, fleas, fungal or bacterial disease, urine scald, dental or mobility problems, or another underlying illness. A rabbit that cannot keep its bottom clean needs more than cosmetic cleaning: the cause also needs attention.
For persistent scratching, our rabbit itching and scratching guide explains signs to report to your vet and treatments to avoid.
Flystrike occurs when flies lay eggs on a rabbit and maggots hatch on the body. It is a life-threatening emergency. If you see eggs or maggots, contact an emergency veterinarian immediately.
Urinary and reproductive problems
Rabbit urine can naturally vary from pale yellow to orange or reddish-brown because of pigments. Visible blood, repeated straining, urine dribbling, a persistently wet underside, thick sludge, reduced urine output, or signs of pain require veterinary assessment. A urine test may be needed to distinguish pigment from blood.
Unspayed female rabbits have a significant risk of uterine disease as they age. Discuss the individual benefits, timing, and anesthetic considerations of spaying or neutering with a rabbit-experienced veterinarian.
Sore hocks and mobility problems
Redness, thinning fur, swelling, sores on the feet, reluctance to move, or difficulty entering the litter box can reflect pododermatitis, arthritis, injury, excess weight, unsuitable flooring, or another condition. Provide dry, supportive flooring and seek veterinary advice before a small sore becomes a deeper infection.
What to do while arranging veterinary care
- Keep your rabbit in a quiet, secure carrier or area at a comfortable temperature.
- Note when they last ate, passed droppings, and urinated; record any sudden changes.
- Take photos of unusual droppings, urine, discharge, wounds, or the litter box if this can be done without delaying care.
- Offer the rabbit’s usual hay, plain water, and familiar leafy greens while you call the clinic, unless a veterinarian gives different instructions.
- Bring a list of medications, recent diet changes, possible toxin exposure, and relevant medical history.
What not to do
- Do not give human painkillers, leftover antibiotics, or another animal’s medication.
- Do not use dog or cat flea products unless a rabbit-experienced veterinarian has approved the exact product. Fipronil is contraindicated in rabbits.
- Do not force-feed a rabbit until a veterinarian has considered and ruled out a dangerous obstruction, or has specifically instructed you to assist-feed.
- Do not use fruit juice, oils, laxatives, or other home remedies as a substitute for diagnosis and treatment.
- Do not delay veterinary care because a rabbit is still alert or accepts a small treat. Rabbits can mask serious illness.
Preventive care that lowers risk
No routine can prevent every illness, but good daily care makes problems less likely and helps you notice them earlier.
- Provide a hay-based diet suited to your rabbit, fresh water, appropriate leafy greens, and measured pellets as advised for their age and health.
- Arrange regular wellness and dental examinations with a rabbit-savvy veterinarian.
- Ask which vaccines are recommended and available where you live; rabbit vaccination schedules vary by country and disease risk.
- Discuss spaying or neutering, particularly the health benefits for female rabbits.
- Provide daily movement, traction, supportive flooring, clean litter areas, and a dry, well-ventilated living space.
- Groom as needed, check the feet and underside, and increase bottom checks during warm weather or if the rabbit has mobility or toileting problems.
- Know the location and hours of a rabbit-capable emergency clinic before you need one.
Frequently asked questions
How can I tell whether my rabbit is sick?
Look for a change from normal in appetite, droppings, movement, posture, breathing, grooming, social behavior, or body weight. One subtle change may be the first clue. If you are unsure, call a rabbit-savvy veterinarian and describe exactly what changed and when.
Can an indoor rabbit still become seriously ill?
Yes. Indoor rabbits can develop dental disease, digestive problems, urinary disease, respiratory illness, parasites, reproductive disease, injury, and other conditions. Indoor housing reduces some risks but does not replace preventive care or vaccination where recommended.
Why is my rabbit losing weight?
Weight loss can result from dental disease, inadequate intake, digestive disease, parasites, kidney or liver disease, cancer, pain, or other problems. Because the cause cannot be identified from weight loss alone, arrange a veterinary examination rather than simply increasing treats or pellets.
Should I treat a sick rabbit at home?
Home observation and supportive steps can help while you contact a clinic, but they should not replace an examination. Medication, assisted feeding, fluid therapy, and temperature support should follow a plan from a veterinarian who knows the rabbit’s condition.
