Common signs of illness in a rabbit include eating less, low energy, weight loss, fewer or no droppings, diarrhea, pain, unusual movement, discharge from the eyes or nose, breathing changes, and changes to the skin, coat, or urine. A single symptom cannot tell you which illness your rabbit has. Contact a rabbit-experienced veterinarian promptly when you notice a clear change; seek emergency care for severe signs such as mouth breathing, seizures, head tilt, serious injury, or suspected poisoning.
Which signs mean your rabbit needs veterinary care?
Rabbits often hide signs of illness, so a change from your rabbit’s usual eating, energy, movement, or droppings matters. House Rabbit Society recommends monitoring behavior and droppings daily. Don’t wait for several symptoms to appear before calling.
| Contact a rabbit-experienced veterinarian promptly | Seek emergency veterinary help |
|---|---|
| Not eating or eating less; lethargy; weight loss; fewer droppings or no droppings; diarrhea; drooling or a wet chin; unusual movement; eye or nasal discharge; changes to skin, coat, or urine. | Breathing through the mouth; seizures; head tilt or loss of balance; significant bleeding or injury; severe abdominal distension; suspected poisoning; noticeable or severe pain. |
Rabbit.org identifies appetite loss together with lethargy as a major emergency signal. If your rabbit stops eating, contact a veterinarian right away rather than waiting to see whether it passes. MSD Veterinary Manual also advises prompt veterinary care for stopped eating or digestive upset and treats diarrhea as a serious warning sign.
Changes in eating, energy, weight, or droppings
Appetite loss and lethargy
Refusing familiar food, eating less, or seeming unusually quiet or weak can be signs of illness. Even one missed meal can be concerning, according to Rabbit.org. These signs are not a diagnosis: appetite loss and lethargy can occur with different conditions.
#1 Best Overall
Weight loss and digestive changes
Unexplained weight loss deserves veterinary attention. So do fewer droppings than usual or no droppings. MSD Veterinary Manual says no droppings for more than 12 hours merits urgent veterinary attention. Diarrhea is also serious and needs prompt veterinary assessment.
Signs of pain or possible dental trouble
A hunched posture or tooth grinding may indicate pain. Drooling, a wet chin, dropping food, or reduced appetite can be associated with dental disease, but these signs do not establish the cause. Contact a veterinarian for an assessment rather than trying to diagnose the problem at home.

Eye, nose, and breathing changes
Eye or nasal discharge and chronic sneezing should not be dismissed. They can have more than one cause, so a veterinarian needs to assess them. Labored breathing also warrants urgent veterinary advice; breathing through the mouth is an emergency sign.
Movement, balance, skin, coat, and urine
Movement and balance
Not hopping or moving normally is a warning sign. A head tilt, loss of balance, or seizure calls for emergency veterinary care.
Skin and coat
Fur loss or red, swollen skin can signal a health problem and should be discussed with a veterinarian.
Urine
Dark red urine appears among the illness signs listed by MSD Veterinary Manual. Some foods can make rabbit urine look reddish, but actual blood may indicate urinary disease. Ask a veterinarian for advice about unexplained red urine rather than assuming its cause.
Temperature: useful context, not a reason to delay care
MSD Veterinary Manual gives a normal rabbit body temperature of 103–104°F (39.4–40°C). It identifies a temperature below 100.4°F (38°C) or above 105°F (40.6°C) as a warning sign. These reference values do not replace veterinary assessment or justify delaying a call when your rabbit has other serious signs.

- Contact a rabbit-experienced veterinarian promptly. Call for appetite loss, lethargy, diarrhea, reduced droppings, unusual movement, or another clear change from your rabbit’s normal behavior.
- Go to an emergency veterinary provider for severe signs. This includes mouth breathing, seizures, head tilt or loss of balance, significant bleeding or injury, severe abdominal distension, suspected poisoning, or noticeable pain.
- Describe what has changed. Tell the clinic what you have observed, when it began, and how eating, energy, movement, and droppings compare with your rabbit’s usual pattern.
Symptoms help a veterinarian decide what to assess, but they do not identify a particular disease by themselves. For example, appetite loss does not prove GI stasis, and discharge does not prove a respiratory infection.
